MULTIPROCESSOR SYSTEM, LIBRARY MODULE, AND DRAWING PROCESSING METHOD

摘要

A multiprocessor system is provided in which a CPU 100 and a GPU 200 are connected via an IOIF 110. A main memory 120 is installed in the CPU 100 and a local memory 220 is installed in the GPU 200. The CPU 100 queues graphics commands that an application 300 has generated using a graphics library 300 into a command buffer 10 in the main memory 120. The GPU 200 reads the graphics commands stored in the command buffer 10 and executes them. The area of the main memory 120 is memory-mapped to an I/O address space and the GPU 200 reads the data memory-mapped to the I/O address space via the IOIF 110 and utilizes the data for graphics computation.
