    摘要: A load balancing in a multiple DRAM system comprises interleaving memory data across two or more memory channels. Access to the memory channels is controlled by memory controllers. Bus masters are coupled to the memory controllers via an interconnect system and memory requests are transmitted from the bus masters to the memory controller. If congestion is detected in a memory channel, congestion signals are generated and transmitted to the bus masters. Memory requests are accordingly withdrawn or rerouted to less congested memory channels based on the congestion signals.

    摘要: A load state of a slave memory is detected and provided to a master device. The master device communicates prefetch access requests to the slave memory based, at least in part, on the detected load state. Optionally, the master device communicates prefetch requests to the slave memory according to a schedule based, at least in part, on the detected load state.
