Abstract
A method and a system for arbitrating accesses to a memory in a data processing system having many memory access units (MAU) and an arbiter are disclosed. The arbiter initially sends a permission signal to each MAU to give each MAU a chance to reset its priority level if necessary. Then each of a first set of top priority MAUs that was not able to access to the memory for a predetermined period of time resets its priority level to a top priority value and sends a second priority value to the arbiter. Thereafter the arbiter selects a MAU among the first set of top priority MAUs and sends an acknowledgement signal to the selected MAU. If none of the first set of top priority MAUs exist, the arbiter identifies a second set of top priority MAUs by checking the predetermined starvation period of each MAU and sends an acknowledgement signal to one of the second set of top priority MAUs.
