Introduce

The F20 is a 16/32-bit RISC microprocessor, which is designed to provide a cost-effective,

low-power capabilities, high performance processor for video application and general

application. The F20 is developed with ARM926-EJS core with separated 16KB instruction

and 16KB data caches. To reduce total system cost, the F20 includes the following

components.
