Interfaces 2.2 PCI Express* Interface This section describes the PCI Express interface capabilities of the processor. See the PCI Express Base Specification for details of PCI Express. The number of PCI Express controllers is dependent on the platform. Refer to Chapter 1 for details. 2.2.1 PCI Express* Architecture Compatibility with the PCI addressing model is maintained to ensure that all existing applications and drivers may operate unchanged.
Interfaces Figure 2-3. Packet Flow Through the Layers Framing Sequence Number Header Data ECRC LCRC Framing Transaction Layer Data Link Layer Physical Layer 2.2.1.1 Transaction Layer The upper layer of the PCI Express architecture is the Transaction Layer. The Transaction Layer's primary responsibility is the assembly and disassembly of Transaction Layer Packets (TLPs). TLPs are used to communicate transactions, such as read and write, as well as certain types of events.
Interfaces 2.2.2 PCI Express* Configuration Mechanism The PCI Express (external graphics) link is mapped through a PCI-to-PCI bridge structure. Figure 2-4.
Interfaces 2.2.3 PCI Express* Port The PCI Express interface on the processor is a single, 16-lane (x16) port that can also be configured at narrower widths. The PCI Express port is being designed to be compliant with the PCI Express Base Specification, Revision 3.0. 2.2.3.1 PCI Express* Lanes Connection Figure 2-5 demonstrates the PCIe lanes mapping. Figure 2-5.
Interfaces 2.3 Direct Media Interface (DMI) Direct Media Interface (DMI) connects the processor and the PCH. Next generation DMI 2.0 is supported. Note: Only DMI x4 configuration is supported. 2.3.1 DMI Error Flow DMI can only generate SERR in response to errors, never SCI, SMI, MSI, PCI INT, or GPE. Any DMI related SERR activity is associated with Device 0. 2.3.2 Processor / PCH Compatibility Assumptions The processor is compatible with the Intel 7 Series Chipset PCH products. 2.3.
Interfaces 2.4 Processor Graphics Controller (GT) New Graphics Engine Architecture includes 3D compute elements, Multi-format hardware assisted decode/encode pipeline, and Mid-Level Cache (MLC) for superior high definition playback, video quality, and improved 3D performance and Media. The Display Engine handles delivering the pixels to the screen, and is the primary channel interface for display memory accesses and “PCI-like” traffic in and out. Figure 2-6.
Interfaces 2.4.1.2 3D Pipeline 2.4.1.2.1 Vertex Fetch (VF) Stage The VF stage executes 3DPRIMITIVE commands. Some enhancements have been included to better support legacy D3D APIs as well as SGI OpenGL*. 2.4.1.2.2 Vertex Shader (VS) Stage The VS stage performs shading of vertices output by the VF function. The VS unit produces an output vertex reference for every input vertex reference received from the VF unit, in the order received. 2.4.1.2.
Interfaces 2.4.1.4 2D Engine The Display Engine fetches the raw data from the memory, puts the data into a stream, converts the data into raw pixels, organizes pixels into images, blends different planes into a single image, encodes the data, and sends the data out to the display device. The Display Engine executes its functions with the help of three main functional blocks – Planes, Pipes, and Ports, except for eDP. The Planes and Pipes are in the processor while the Ports reside in the PCH.
Interfaces 2.4.2 Processor Graphics Display The Processor Graphics controller display pipe can be broken down into three components: • Display Planes • Display Pipes • DisplayPort and Intel FDI Figure 2-7. Processor Display Block Diagram VGA Memory Host Interface (Outside of Display Engine) 2.4.2.
Interfaces 2.4.2.2 Display Pipes The display pipe blends and synchronizes pixel data received from one or more display planes and adds the timing of the display output device upon which the image is displayed. The display pipes A, B, and C operate independently of each other at the rate of 1 pixel per clock. They can attach to any of the display ports. Each pipe sends display data to eDP or to the PCH over the Intel Flexible Display Interface (Intel FDI). 2.4.2.
Interfaces 2.5 Platform Environment Control Interface (PECI) The PECI is a one-wire interface that provides a communication channel between a PECI client (processor) and a PECI master. The processor implements a PECI interface to: • Allow communication of processor thermal and other information to the PECI master. • Read averaged Digital Thermal Sensor (DTS) values for fan speed control. 2.6 Interface Clocking 2.6.1 Internal Clocking Requirements Table 2-5.

Technologies 3.1.4 Intel® Virtualization Technology (Intel® VT) for Directed I/O (Intel® VT-d) Features The processor supports the following Intel VT-d features: • Memory controller and processor graphics comply with Intel® VT-d 1.
Technologies 3.2 Intel® Trusted Execution Technology (Intel® TXT) Intel Trusted Execution Technology (Intel TXT) defines platform-level enhancements that provide the building blocks for creating trusted platforms. The Intel TXT platform helps to provide the authenticity of the controlling environment such that those wishing to rely on the platform can make an appropriate trust decision.
Technologies 3.4 Intel® Turbo Boost Technology Intel® Turbo Boost Technology is a feature that allows the processor core to opportunistically and automatically run faster than its rated operating frequency/render clock if it is operating below power, temperature, and current limits. The Intel Turbo Boost Technology feature is designed to increase performance of both multi-threaded and single-threaded workloads. Maximum frequency is dependant on the SKU and number of active cores.
Technologies 3.5 Intel® Advanced Vector Extensions (Intel® AVX) Intel Advanced Vector Extensions (Intel AVX) is the latest expansion of the Intel instruction set. It extends the Intel Streaming SIMD Extensions (Intel SSE) from 128bit vectors to 256-bit vectors.

This capability will be made available to programmers through the new RDRAND instruction. The resultant random number generation capability is designed to comply with existing industry standards in this regard (ANSI X9.82 and NIST SP 800-90).
Technologies • More efficient MSR interface to access APIC registers. — To enhance inter-processor and self directed interrupt delivery as well as the ability to virtualize the local APIC, the APIC register set can be accessed only through MSR based interfaces in the x2APIC mode. The Memory Mapped IO (MMIO) interface used by xAPIC is not supported in the x2APIC mode.
Power Management 4 Power Management This chapter provides information on the following power management topics: • Advanced Configuration and Power Interface (ACPI) States • Processor Core • Integrated Memory Controller (IMC) • PCI Express* • Direct Media Interface (DMI) • Processor Graphics Controller Figure 4-1.
Power Management 4.1 Advanced Configuration and Power Interface (ACPI) States Supported The ACPI states supported by the processor are described in this section. 4.1.1 System States Table 4-1. System States State G0/S0 G1/S3-Cold Description Full On Suspend-to-RAM (STR). Context saved to memory (S3-Hot is not supported by the processor). G1/S4 Suspend-to-Disk (STD). All power lost (except wakeup on PCH). G2/S5 Soft off. All power lost (except wakeup on PCH). Total reboot. G3 Mechanical off.
Power Management 4.1.4 PCI Express* Link States Table 4-4. PCI Express* Link States State Description L0 Full on – Active transfer state. L0s First Active Power Management low power state – Low exit latency L1 Lowest Active Power Management – Longer exit latency L3 Lowest power state (power-off) – Longest exit latency 4.1.5 Direct Media Interface (DMI) States Table 4-5.
Power Management 4.2 Processor Core Power Management While executing code, Enhanced Intel SpeedStep Technology optimizes the processor’s frequency and core voltage based on workload. Each frequency and voltage operating point is defined by ACPI as a P-state. When the processor is not executing code, it is idle. A low-power idle state is defined by ACPI as a C-state. In general, lower power C-states have longer entry and exit latencies. 4.2.
Power Management Figure 4-2. Idle Power Management Breakdown of the Processor Cores Thread 0 Thread 1 Thread 0 Core 0 State Thread 1 Core 1 State Processor Package State Entry and exit of the C-States at the thread and core level are shown in Figure 4-3. Figure 4-3.
Power Management 4.2.3 Requesting Low-Power Idle States The primary software interfaces for requesting low power idle states are through the MWAIT instruction with sub-state hints and the HLT instruction (for C1 and C1E). However, software may make C-state requests using the legacy method of I/O reads from the ACPI-defined processor clock control registers, referred to as P_LVLx.
Power Management 4.2.4.2 Core C1 / C1E State C1/C1E is a low power state entered when all threads within a core execute a HLT or MWAIT(C1/C1E) instruction. A System Management Interrupt (SMI) handler returns execution to either Normal state or the C1/C1E state. See the Intel® 64 and IA-32 Architecture Software Developer’s Manual, Volume 3A/3B: System Programmer’s Guide for more information. While a core is in C1/C1E state, it processes bus snoops and snoops from other threads.
Power Management 4.2.5 Package C-States The processor supports C0, C1/C1E, C3, and C6 power states. The following is a summary of the general rules for package C-state entry. These apply to all package Cstates unless specified otherwise: • A package C-state request is determined by the lowest numerical core C-state amongst all cores. • A package C-state is automatically resolved by the processor depending on the core idle power states and the status of the platform components.
Power Management Figure 4-4. Package C-State Entry and Exit C0 C3 C1 4.2.5.1 C6 Package C0 Package C0 is the normal operating state for the processor. The processor remains in the normal state when at least one of its cores is in the C0 or C1 state or when the platform has not granted permission to the processor to go into a low power state. Individual cores may be in lower power idle states while the package is in C0. 4.2.5.
Power Management 4.2.5.3 Package C3 State A processor enters the package C3 low power state when: • At least one core is in the C3 state • The other cores are in a C3 or lower power state, and the processor has been granted permission by the platform • The platform has not granted a request to a package C6 state but has allowed a package C6 state In package C3-state, the L3 shared cache is valid. 4.2.5.
Power Management 4.3.2 DRAM Power Management and Initialization The processor implements extensive support for power management on the SDRAM interface. There are four SDRAM operations associated with the Clock Enable (CKE) signals that the SDRAM controller supports. The processor drives four CKE pins to perform these operations. The CKE is one means of power saving. When CKE is off, the internal DDR clock is disabled and the DDR power is reduced.
Power Management It is important to understand that since the power down decision is per rank, the MC can find a lot of opportunities to power down ranks, even while running memory intensive applications; savings may be significant (up to a few Watts, depending on DDR configuration). This becomes more significant when each channel is populated with more ranks.
Power Management The target behavior is to enter self-refresh for the package C3 and C6 states as long as there are no memory requests to service. 4.3.2.3 Dynamic Power Down Operation Dynamic power down of memory is employed during normal operation. Based on idle conditions, a given memory rank may be powered down. The IMC implements aggressive CKE control to dynamically put the DRAM devices in a power down state.
Power Management 4.4 PCI Express* Power Management • Active power management support using L0s and L1 states. • All inputs and outputs disabled in L2/L3 Ready state. Note: PCIe* interface does not support Hot-Plug. Note: An increase in power consumption may be observed when PCIe Active State Power Management (ASPM) capabilities are disabled. 4.5 DMI Power Management • Active power management support using L0s/L1 state. 4.6 Graphics Power Management 4.6.
Power Management 4.6.4 Intel® Smart 2D Display Technology (Intel® S2DDT) Intel S2DDT reduces display refresh memory traffic by reducing memory reads required for display refresh. Power consumption is reduced by less accesses to the IMC. S2DDT is only enabled in single pipe mode. Intel S2DDT is most effective with: • Display images well suited to compression, such as text windows, slide shows, and so on. Poor examples are 3D games.

Electrical Specifications 7.11 Platform Environmental Control Interface (PECI) DC Specifications PECI is an Intel proprietary interface that provides a communication channel between Intel processors and chipset components to external thermal monitoring devices. The processor contains a Digital Thermal Sensor (DTS) that reports a relative die temperature as an offset from Thermal Control Circuit (TCC) activation temperature.
Electrical Specifications 7.11.2 DC Characteristics The PECI interface operates at a nominal voltage set by VCCIO. The DC electrical specifications shown in Table 7-10 are used with devices normally operating from a VCCIO interface supply. VCCIO nominal levels will vary between processor families. All PECI devices will operate at the VCCIO level determined by the processor installed in the system. For specific nominal VCCIO levels, refer to Table 7-5. Table 7-10.

DDR Data Swizzling 9 DDR Data Swizzling To achieve better memory performance and timing, Intel Design performed DDR Data pin swizzling that allows a better use of the product across different platforms. Swizzling has no effect on functional operation and is invisible to the operating system/software. However, during debug, swizzling needs to be taken into consideration. Therefore, swizzling information is presented in this chapter.
