MULTI PROCESSOR SYSTEM HAVING FLASH-LESS BOOTING FUNCTION IN MEMORY LINK ARCHITECTURE

摘要

PURPOSE: A multi processor system including a flash-less booting function in memory link architecture is provided to adopt a multi port semiconductor memory device as a common memory, thereby increasing a booting speed and simplifying a system structure. CONSTITUTION: A multiport semiconductor memory device(300) includes a shared memory area and a mailbox. The first processing device(100) is connected to the multi port semiconductor memory device and includes an internal ROM storing a default setting code for DRAM control. The second processing device(200) exchanges the first processing device and data through the multi port semiconductor memory device. A non-volatile semiconductor memory device(400) is connected to the second processing unit.
