4.4.4. On-Chip RAM Functional Description

The on-chip RAM uses a 64-bit slave interface which consists of a single-ported SRAM. The boot software copies initial software (pre-Bootloader) from the boot device into the on-chip RAM and executes the initial software by jumping to a known address in the on-chip RAM. The on-chip RAM also serves as a general-purpose memory that allows the FPGA fast access.

The on-chip RAM interfaces to the following:
  • Clock manager
  • Reset manager
  • System manager
  • Cache Coherency Unit (CCU)
  • L3 interconnect
