Scratchpad memory vs cache
WebOct 29, 2011 · The main difference between shared memory and the L1 is that the contents of shared memory are managed by your code explicitly, whereas the L1 cache is automatically managed. Shared memory is also a better way to exchange data between threads in a block with predictable timing. My rule of thumb is: unpredictable reads and … WebMar 31, 2016 · A cache uses access patterns to populate data within the cache. It has extra hardware to track the backing address and may have communication with other system entities (SMP) to track when a cache line is dirty (someone else has written something to primary memory).. The 'TCM' (tightly coupled memory) is fast, probably SRAM multi …
