Multiprocessor System, Library Module And Rendering Processing Method

摘要

A multiprocessor system in which a CPU (100) and a GPU (200) are interconnected via an IOIF (110) is provided. A main memory (120) is installed on the CPU (100) side and a local memory (220) is installed in the GPU (200) side. The CPU (100) queues a graphics command generated with a graphics library (300) by an application (310) to a command buffer (10) in the main memory (120). The GPU (200) reads and executes the graphics command stored in the command buffer (10). The area of the main memory (120) is memory-mapped in an I/O address space. The GPU (200) reads data memory-mapped in the I/O address space via the IOIF (110) and uses it for graphics operation.
