An integrated circuit device and method of communication therewith

摘要

There is disclosed a single chip integrated circuit device including a message converter connected to an on-chip bus system by a first set of pins equal in number to the bit width of the bus system. The message converter has a second set of pins which are less in number than the first set. The message converter has reduced pin data receiving circuitry for receiving messages and data transmit circuitry for formulating messages from information received from the bus system. Each message has a message identifier. There is also disclosed a method of effecting memory access requests using a message converter. <IMAGE>
