1 Introduction In the design of RISC CPU, the processing of transfer instructions has a critical impact on the performance of the processor. Transfer instructions determine the execution orde...[Details]

This is a simple program written to test timer 0: the goal is to have the first and second LED lights light up in a cycle, and the third light lights up once every one second. The lighting time of th...[Details]

1.7.1 Change UART2 to a normal serial port driver The S3C2440 chip has 3 serial ports: UART0, 1, 2. The Linux-2.6.32.2 we downloaded already has a complete driver for UART0, 1, but it uses infrared...[Details]

1. Don't say "Give me a code!" as the first sentence after seeing someone else's reply. You should think about why. When you figure it out yourself and refer to other people's tips, you will know the ...[Details]
