A controller for a shared memory is disclosed. The controller comprises a transaction scanner configured to scan-in a plurality of transactions to access the shared memory and to divide the transactions into beat-level memory access commands. The controller also comprises a command super-arbiter comprising a plurality of command arbiters corresponding to a plurality of shared memory blocks in the shared memory. The command super-arbiter is configured to access a quality of service for each of the transactions, arbitrate the beat-level memory access commands associated with the transactions based on the quality of service for each of the plurality of transactions, and dispatch the beat-level memory access commands to the shared memory blocks based on results of arbitrating the beat-level memory access commands.
