Abstract
A data processing system includes a multiport memory module including a plurality of first ports and a plurality of second ports. The data processing system includes a plurality of first buses and a plurality of second buses. A plurality of hardware acceleration modules configured to communicate with respective ones of the plurality of first ports via respective ones of the plurality of first buses. The data processing system includes a processor module. A random access memory (RAM) module configured to store data. The processor module and the RAM module communicate with the multiport memory module via respective ones of the plurality of second buses. A shared bus includes a first bus portion configured to communicate with the plurality of hardware acceleration modules at a first rate. A second bus portion configured to communicate with the processor module and the RAM module at a second rate that is different than the first rate. A bus bridge that communicates with the first bus portion and the second bus portion.
