<P>PROBLEM TO BE SOLVED: To provide a method and device for accessing shared resources. <P>SOLUTION: A memory controller comprises a bandwidth control circuit 620. The bandwidth control circuit comprises a programmable hardware register 710 and a hardware accumulator 720. The accumulator 720 is initialized to a predetermined value (e.g., 0.00000000) and, in each cycle, a number programmed in the programmable register 710 is automatically added to the accumulator 720. When the bit 8 (most significant bit) of the accumulator 720 is set, a corresponding request is arbitrated in that cycle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
