用ＶＨＤＬ在CPLD/FPGA上实现与PC机的RS232通信-This UART (Universal Asynchronous Receiver Transmitter) is designed to make an interface between a RS232 line and a wishbone bus, or a microcontroller, or an IP core. It works fine connected to the serial port of a

Expandable cache proposed by Bournoutian and Orailoglu is very efficient in reducing miss rate and energy consumption with small area overhead. However, the original expandable cache with only one expansion scheme may lead to thrashing problems. In t

该项目从需要具有强大而简单的以VHDL编写的SPI接口核心开始，用于通用的FPGA到设备接口。 所产生的内核产生小而高效的电路，从非常慢的SPI时钟到超过50MHz的SPI时钟。-This project started the need to have robust yet simple SPI interface cores written in VHDL to use in generic FPGA-to-device interfacing. The resulting co
