T8051

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.

里面含有vhdl和verilog 版本,很好用!dct变换用得很多啊!(Which contains a VHDL and Verilog versions of very good use! Dct transform with a lot ah!)

说明：  是用VHDL语言编写的乐曲演奏程序，详细的写了各个模块的子程序(VHDL language is the music playing program)

在fpga中对GPS信息采集程序。具有很好的参考性(In the fpga in the GPS information collection procedures. Has a very good reference)
