Abstract
One embodiment sets forth a technique for dynamically mapping addresses to banks of a multi-bank memory based on a bank mode. Application programs may be configured to perform read and write a memory accessing different numbers of bits per bank, e.g., 32-bits per bank, 64-bits per bank, or 128-bits per bank. On each clock cycle an access request may be received from one of the application programs and per processing thread addresses of the access request are dynamically mapped based on the bank mode to produce a set of bank addresses. The bank addresses are then used to access the multi-bank memory. Allowing different bank mappings enables each application program to avoid bank conflicts when the memory is accesses compared with using a single bank mapping for all accesses.
