Table 8-12 shows the EVE-level effective bus width and the resulting peak bandwidth. In general, the effective bus width is the minimum of the bus width values between a given initiator and given target. For example, the DMEM port is effectively 4 bytes wide when accessed by ARP32 and is effectively 16 bytes wide when accessed by DMA. Similarly, VCOP memories are 4 bytes, 32 bytes and 16 bytes wide when accessed by ARP32, VCOP, and TCn, respectively.
