Xilinx FPGA using leftover multipliers and block RAM

这个是DE2上的SDRAM 四个端口的驱动代码，相当实用！(This is a four-port SDRAM on a DE2 driver code, very useful!)

基于verilog的FIR滤波器程序设计（调试过的）-verilog

说明：  access must be conf urr arr

说明：  libero soc工程，实现通过串口接收到单字节数据后并返回发送给上位机(Libero SOC project, which realizes receiving single byte data through serial port and sending it back to host computer)

说明：  简单的单周期CPU设计，实现的指令有：算术运算指令、逻辑运算指令、移位指令、比较指令、存储器读/写指令、分支指令、跳转指令、停机指令。(Simple single-cycle CPU design,The instructions implemented are as follows:Arithmetic operation instruction, logical operation instruction, shift instruction, comparison instruction, memory read/write instruction, branch instruction, jump instruction, stop instruction.)

实现arm与fpga之间通过gpmc总线通信(the device of fpga)

一位LED显示的VHDL程序，挺简单的，买的开发板里面带的-An LED display of the VHDL program, quite simply, to buy development board inside the zone

This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM. As of this time, the DDR interface only works up to 120 MHz. At 130, DDR data can be read but not written. NOTE: the test bench cannot be simulated with DDR enabled because the Altera pads do not have the correct delay models. * How to program the flash prom with a FPGA programming file 1. Create a hex file of the programming file with Quartus. 2. Convert it to srecord and adjust the load address: objcopy --adjust-vma=0x800000 output_file.hexout -O srec fpga.srec 3. Program the flash memory using grmon: flash erase 0x800000 0xb00000 flash load fpga.srec-This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM.
