ABSTRACT:
A system for communicating with a processor within an integrated circuit can include a dual-bus adapter (115) coupled to the processor (105) through a first communication channel (110) and a second communication channel (120). The dual-bus adapter further can be coupled to a memory map interface (135) through which at least one peripheral device communicates with the processor. Single word operations can be exchanged between the processor and the dual-bus adapter through the first communication channel. Burst transfer operations can be performed by exchanging signaling information between the processor and the dual-bus adapter over the first communication channel and exchanging data words between the processor and the dual-bus adapter through the second communication channel.
