WebPrefetching is all about reducing the latency of the memory-accesses. In a perfect scenario, where latency corresponds to X calculation-steps, we would have a oracle, which would tell us which memory we would access in X calculation-steps, the prefetching of this data would be launched and it would arrive just in-time X calculation-steps later. WebNov 23, 2024 · DDR3 SDRAM's prefetch buffer size is 8n (eight datawords per memory access), i.e. for 16-bit datword prefetch buffer size is 8*16=128 bits. From 10-bit column address of 16-bit dataword the 7 msb select 128-bit chunk for prefetch on memory access.
