INTER-PROCESSOR COMMUNICATION DEVICE HAVING BURST TRANSFER FUNCTION, SYSTEM INCLUDING THE INTER-PROCESSOR COMMUNICATION DEVICE, AND DEVICE DRIVER FOR OPERATING THE INTER-PROCESSOR COMMUNICATION DEVICE

摘要

PURPOSE: An inter-processor communication system capable of performing burst transfer, a system including the same, and a device driver for executing the same are provided to reduce the number of memories needed for the system by offering an exclusive storage region to each processor. CONSTITUTION: A first port(431) is connected to a first processor. A second port(432) is connected to a second processor. A share storage region(412) is selectively accessed by the first or second processor through the first or second port. The share storage region stores a plurality of data packets transferred between the first processor and the second processor. Mailbox regions(422,423) store a command and data transfer information for the data packets, which are transferred between the first processor and the second processor.
