Abstract
To accomplish this, this memory access system monitors a use-memory-bandwidth which indicates a total of memory bandwidths used between a memory and a plurality of masters, and determines whether the use-memory-bandwidth is equal to or larger than the first threshold. Based on the above-described determination result, this memory access system also restricts access to the memory by a master of low priority out of the plurality of masters.
