• Multi-port SRAM controller manages automatically interleaved addressing of SRAM blocks

• Statistically, buffers may not be in the same memory bank

• Latency can be divided by 4

• Concurrent accesses are optimized

• Burst from DMAs are generally to consecutive addresses

• Masters can access the SRAM at each cycle
