Web20 de mai. de 2024 · How big is the L1 cache? The L1 cache size is 64 K. However, to preserve backward compatibility, a minimum of 16 K must be allocated to the shared memory, meaning the L1 cache is really only 48 K in size. Using a switch, shared memory and L1 cache usage can be swapped, giving 48 K of shared memory and 16 K of L1 …
