DEVICE FOR INTEGRATING CPU-PCI BRIDGE HAVING INTEGRATED MEMORY, INTEGRATED MEMORY, AND METHOD FOR OPERATING INTEGRATED MEMORY

摘要

PURPOSE: A device for integrating a CPU-PCI(Peripheral Component Interconnect) bridge having an integrated memory, the integrated memory, and a method for operating the integrated memory are provided to efficiently use the memory by supporting a CPU-PCI integrating device as storing the data for a CPU function/PCI bridge function module in the memory of the CPU-PCI integrating module. CONSTITUTION: The CPU-PCI bridge integrating module(100) has the CPU function module(110) performing a CPU function and the PCI bridge function module(120) performing a PCI bridge function. A PCI mater(200) transmits/receives data with the CPU-PCI bridge integrating module through the PCI bridge function of the CPU-PCI bridge integrating module by connecting to the CPU-PCI bridge integrating module through a PCI bus. The integrated memory(300) is connected to the CPU-PCI bridge integrating module through a local processor bus, and has a program/data area(310,320) for storing a program and the data for the CPU function module and a PCI bus shared area(330) for storing the data transmitted/received from the PCI master through the PCI bridge function module.
