摘要
A collaborative bus arbitration multiplex architecture includes of a main memory, a bus, a plurality of BMPDs, and a BAM. Arbitration can be done according to the following steps of awaiting whether any of the BMPDs renders any request for access; B) identifying whether the access authority of the bus is being fetched by any other BMPDs; C) identifying whether the main memory to which the request for access corresponds have any record that the corresponding BMPD needs special treatment; D) identifying whether all of the BMPDs have rendered the requests for access; E) according to a generic arbitration principle, identifying whether the corresponding BMPDs indicated in the steps C) and D) win the access authority; F) yielding the access authority of the bus to the BMPDs winning the access authority as indicated in the step E); and G) accessing the main memory.
