DES是一种分组密码。假定明文m是由0和1组成的长度为64位的符号串，密钥k也是64位的0、1符号串。...

To write assembly code to implement a circular First In First Out (FIFO) buffer in the data memory of PIC18F452 microcontroller, using the microcontroller’s direct addressing mode and indirect addressing mode. To expand on the FIFO assignment and implement the FIFO solution on the QWIKFLASH PIC target board and display the FIFOSTATUS as LED indicators. Recall: Flags within a file register called FIFOSTATUS: • Bit 0: FIFO_full • Bit 1: FIFO_empty • Bit 2: attempt_2_read when FIFO_empty • Bit 3: attempt_2_write when FIFO_full
