Shared memory bank size
Webb8 feb. 2009 · Shared memory is of size 16KB. It is divided into 16 banks each having 1KB. In the shared memory successive 32 bit words belong to successive banks (e.g., if we access the 18 th word it belongs to 18%16 = 2nd bank ). Each bank has a bandwidth of 32 bits per clock cycle i.e., at any clock cycle a bank can give only 32 bits i.e., a word. Webb6 mars 2024 · 共享内存bank conflicts. 为了实现内存高带宽的同时访问，shared memory被划分成了可以同时访问的等大小内存块 (banks)。. 因此，内存读写n个地址的行为则可以以b个独立的bank同时操作的方式进行，这样有效带宽就提高到了一个bank的b倍。. 然而，如果多个线程请求的 ...
