LOCK-FREE MEMORY CONTROLLER AND MULTIPROCESSOR SYSTEM USING THE LOCK-FREE MEMORY CONTROLLER

摘要

PURPOSE: A lock-free memory controller and a multiprocessor system using the lock-free memory controller are provided to process shared data in parallel without a need that each processor uses a locking function, thereby linearly increasing processing performance due to an increase in the number of processors. CONSTITUTION: A memory(610) stores shared data. A processor(620) manages a data block of the memory as one data area. A memory controller(630) provides specific data to the processor by a control signal of the processor. If the control signal is a write command, the memory controller reads data of a write address from the memory, stores the data in a temporary buffer, stores write data in a corresponding bit of the temporary buffer, and stores the data of the temporary buffer in the memory.
