摘要:
A microprocessor suitable for processing a large quantity of graphics data. Graphics processing apparatus and method using the microprocessor are also disclosed.
The microprocessor (1) independent of a CPU has two ports (102, 103), and performs an instruction fetch and a data access or a memory access simultaneously to two memories (3, 10; 3, 4, 10) coupled through separate buses.
In the graphics processing apparatus in which this microprocessor is employed, the graphics transfer between a system memory (10) and a frame memory (4) can be performed at higher speed.
