ADSP-21061/ADSP-21061L Single-Cycle Fetch of Instruction and Two Operands The ADSP-21061 features an enhanced Harvard architecture in which the data memory (DM) bus transfers data and the program memory (PM) bus transfers both instructions and data (Figure 1 on Page 1). With its separate program and data memory buses and on-chip instruction cache, the processor can simultaneously fetch two operands and an instruction (from the cache), all in a single cycle.

ADSP-21061/ADSP-21061L The serial ports can operate with little-endian or big-endian transmission formats, with word lengths selectable from 3 bits to 32 bits. They offer selectable synchronization and transmit modes as well as optional μ-law or A-law companding. Serial port clocks and frame syncs can be internally or externally generated. The serial ports also include keyword and key mask features to enhance interprocessor communication.
ADSP-21061/ADSP-21061L Program Booting The internal memory of the ADSP-21061 can be booted at system power-up from either an 8-bit EPROM, or a host processor. Selection of the boot source is controlled by the BMS (boot memory select), EBOOT (EPROM boot), and LBOOT (host boot) pins. 32-bit and 16-bit host processors can be used for booting. PORTING CODE FROM THE ADSP-21060 OR ADSP-21062 The ADSP-21061 is pin compatible with the ADSP-21060/ ADSP-21061/ADSP-21062 processors.
ADSP-21061/ADSP-21061L Board Support Packages for Evaluation Hardware RELATED SIGNAL CHAINS Software support for the EZ-KIT Lite evaluation boards and EZExtender daughter cards is provided by software add-ins called Board Support Packages (BSPs). The BSPs contain the required drivers, pertinent release notes, and select example code for the given evaluation hardware. A download link for a specific BSP is located on the web page for the associated EZ-KIT or EZExtender product.
ADSP-21061/ADSP-21061L PIN FUNCTION DESCRIPTIONS ADSP-21061 pin definitions are listed below. All pins are identical on the ADSP-21061 and ADSP-21061L. Inputs identified as synchronous (S) must meet timing requirements with respect to CLKIN (or with respect to TCK for TMS, TDI). Inputs identified as asynchronous (A) can be asserted asynchronously to CLKIN (or to TCK for TRST).
ADSP-21061/ADSP-21061L Table 2. Pin Descriptions (Continued) Pin ACK Type I/O/S Function Memory Acknowledge. External devices can deassert ACK (low) to add wait states to an external memory access. ACK is used by I/O devices, memory controllers, or other peripherals to hold off completion of an external memory access. The ADSP-21061 deasserts ACK as an output to add wait states to a synchronous access of its internal memory.

When EBOOT is low, the LBOOT and BMS inputs determine booting mode. See the table in the BMS pin description below. This signal is a system configuration selection that should be hardwired.

ADSP-21061/ADSP-21061L TARGET BOARD CONNECTOR FOR EZ-ICE PROBE The ADSP-2106x EZ-ICE Emulator uses the IEEE 1149.1 JTAG test access port of the ADSP-2106x to monitor and control the target board processor during emulation. The EZ-ICE probe requires the ADSP-2106x’s CLKIN, TMS, TCK, TDI, TDO, and GND signals be made accessible on the target system via a 14-pin connector (a 2-row, 7-pin strip header) such as that shown in Figure 5.

ADSP-21061/ADSP-21061L DMA Handshake These specifications describe the three DMA handshake modes. In all three modes, DMARx is used to initiate transfers. For Handshake mode, DMAGx controls the latching or enabling of data externally. For External Handshake mode, the data transfer is controlled by the ADDR31–0, RD, WR, SW, PAGE, MS3–0, ACK, and DMAGx signals. For Paced Master mode, the data transfer is controlled by ADDR31–0, RD, WR, MS3–0, and ACK (not DMAG).

ADSP-21061/ADSP-21061L TEST CONDITIONS IOL Output Disable Time Output pins are considered to be disabled when they stop driving, go into a high impedance state, and start to decay from their output high or low voltage. The time for the voltage on the bus to decay by V is dependent on the capacitive load, CL, and the load current, IL. This decay time can be approximated by the following equation: TO OUTPUT PIN 1.
