8259中断控制器，参考网上的源码，但自己已经调通，并且应用在控制卡和通信卡上。-8259 interrupt controller, online reference source, but he had transferred Qualcomm, and applications in the control card and communication card.

在quartus II环境下用Verilog实现了8255, 8253, 8259, 8250, DAC0832, ADC0809等微机接口芯片，硬件设计实验课的作品，有些芯片的功能有所简化，但最基本的功能已实现，有完整的时序仿真波形-In quartus II environment achieved with Verilog 8255, 8253, 8259, 8250, DAC0832, ADC0809 and other computer interface chip, hardware
