Expand description

Clean the full L1 data cache.

ยงGenerics

  • A: log2(ASSOCIATIVITY) rounded up to the next integer if necessary. For example, a 4-way associative cache will have a value of 2 and a 8-way associative cache will have a value of 3.
  • N: log2(LINE LENGTH). For example, a 32-byte line length (4 words) will have a value of 5.
  • S: log2(NUM OF SETS). For systems with a fixed cache size, the number of sets can be calculated using CACHE SIZE / (LINE LENGTH * ASSOCIATIVITY). For example, a 4-way associative 32kB L1 cache with a 32-byte line length (4 words) will have 32768 / (32 * 4) == 256 sets and S will have a value of 8.
