On-Chip Single-Access RAM (SARAM)
The SARAM is located at the CPU byte address range 01 0000h - 04FFFFh and is composed of 32 blocks
of 4K words each (see
of 4K words each (see
). Each SARAM block can perform one access per cycle (one read or one
write). SARAM can be accessed by the internal program, data, and DMA buses.
As shown in
, the DMA controllers access SARAM at an address offset 0x0008_0000 from the
CPU memory byte address space.
