Patent ID: 8630181

Claim:
A communication system for transmitting data from a first circuit over a communication channel to a second circuit, wherein said data can have a first priority and a second priority, comprising: a separation circuit configured for: a) receiving said data transmitted over said communication channel; b) detecting the priority of said data transmitted over said communication channel; c) separating said data transmitted over said communication channel according to their priority into data with said first priority and data with said second priority; and d) transmitting said data with said second priority to said second circuit; a first-in first-out (FIFO) memory configured for: a) receiving said data with said first priority from said separation circuit; b) temporarily saving said data with said first priority; and c) transmitting said data saved temporarily in said memory to said second circuit; a control circuit configured for: a) detecting the status of said memory; and b) transmitting a control signal determined according to the status of said memory to said first circuit.
