Abstract: A processing system and method for communicating in a processing system over a bus is disclosed. The processing system includes a receiving device, a bus having first, second and third channels, and a sending device configured to address the receiving device on the first channel, and read a payload from the receiving device on the second channel, the sending device being further configured to write a first portion of a payload to the receiving device on the first channel and a second portion of the payload to the receiving device on the third channel.

Abstract: Dynamic access control for communicating a data packet over a multiple access communication network with a forward channel and a multiple access reverse channel which maintains utilization even when the arrival rate of packets for transmission exceeds the departure rate is provided by a broadcast dynamic access control parameter which regulates access to the multiple access reverse channel. A subscriber device wishing to transmit a data packet on the reverse channel receives the broadcast dynamic access control parameter from a base station on the network, generates an access control limit value and only attempts to transmit the data packet if the access control limit value satisfies the dynamic access control parameter. The dynamic access control parameter is updated by the base station based on a determined success rate and collision rate for transmissions on the reverse channel.
