Chapter 4: System Addresses
4.2 System Bus Masters
The CPUs and AXI_ACP see the same memory map, except the CPUs have a private bus to access their
private timer, interrupt controller, and shared L2 cache / SCU registers. The AXI_HP interfaces provide
high bandwidth to the DDR DRAM and OCM memory. The other system bus masters include:
• DMA controller, see Chapter 9, DMA Controller
• Device configuration interface (DevC), see Chapter 6, Boot and Configuration
• Debug access port (DAP), see Chapter 28, System Test and Debug
• PL bus master controllers attached to AXI general purpose ports (S_AXI_GP[1:0]), see Chapter 5,
Interconnect and Chapter 21, Programmable Logic Description
• AHB bus master ports with local DMA units (Ethernet, USB, and SDIO)
4.3 SLCR Registers
The System-Level Control registers (SLCR) consist of various registers that are used to control the PS
behavior. These registers are accessible via the central interconnect using load and store instructions.
The detailed descriptions for each register can be found in Appendix B, Register Details. A summary
of the SLCR registers with their base addresses is shown in Table 4-3.
