Can someone help me figuring out this Numerical ? , What's the term "warp-around" used for in it ? . Although i tried for AI mentor , i still seek more clarity in explaination

Quick AnswerWarp-around is a cyclic mapping of consecutive c-byte chunks onto the k banks, wrapping back to bank 0 after bank k-1. It can cause multiple iterations to fetch a block if some banks get loaded more than once within a block. Key StepsFor the given data: block = 64 bytes, c = 2, so number of chunks = 64/2 = 32. Banks = k = 24. Chunks map to banks 0..23 in the first pass; chunks 24..31 map to banks 0..7 (wraps around). This requires 2 iterations (one full pass over 24 banks, then a second pass for the remaining 8 chunks). Time per iteration = decode time (k/2) + bank access latency = 24/2 + 80 = 12 + 80 = 92 ns. Total latency = 2 × 92 ns = 184 ns. Answer: 184 ns (option d). — KG AI Mentor 🤖
