ABSTRACT:
Requestors acquire tokens before issuing access requests to a memory controller. The access requests issued are accumulated in a command queue of the memory controller. When the amount of access requests accumulated in the command queue is smaller than or equal to a first threshold, or in level 0, tokens are generated at a rate equivalent to 200% of a bus bandwidth. If the amount of accumulation is greater than the first threshold and is smaller than or equal to a second threshold, i.e., in level 1, tokens are generated at a rate equivalent to the bus bandwidth. If the amount of accumulation exceeds the second threshold, the token generation is stopped.
