read/write allocate
Certainly! Here's an explanation of write allocate and read allocate in the context of AXI4's AWCACHE and ARCACHE signals: Write Allocate and Read Allocate in AXI4 Context Both write allocate and read allocate are bits within the 4-bit AWCACHE (write address channel) and ARCACHE (read address channel) signals. They control how the cache behaves when a write or read transaction occurs, specifically whether the cache allocates a cache line on that access. 1. Read Allocate Definition: When the read allocate bit is set, it indicates that the cache should allocate a cache line on a read miss. Behavior: If the requested data is not present in the cache (a cache miss), the cache will fetch the data from memory and allocate a new cache line to store it. This improves performance for subsequent accesses to the same data. If Read A...
