摘  要：研討基于FPGA開(kāi)發(fā)平臺(tái)實(shí)現(xiàn)的四串口擴(kuò)展模塊設(shè)計(jì)方法。在通信過(guò)程中串口的波特率可以很方便的進(jìn)行設(shè)置。該設(shè)計(jì)方法點(diǎn)在于其具有經(jīng)濟(jì)性、易實(shí)現(xiàn)性和良好的可移植性，有著很強(qiáng)的通用性和推廣價(jià)值。 關(guān)鍵詞：接口技術(shù)   串口擴(kuò)展   FPGA   Verilog HDL Abstract: With the rapid development of electronic technology,muchattention is paid to serial communication interface which is a primary communication interface.This paper introduce A method of four serials extension whi[登陸后可查看全文]
