最小的CPU软核设计，经典，强烈推荐！(VHDL)

kata

该设计包包括CPU的VHDL源代码、示例代码、说明文档、编译器和仿真器及其源代码。
本人采用Quartus II 4.2在CPLD EPM3064A中验证，需要36个逻辑单元。
新手发贴，请多多请教！
穷啊，不得已收费，别扔臭鸡蛋哈，觉得可以就帮我顶一下，新人需要鼓励，呵呵

压缩包中readme.txt文件如下：
ASM/
        - example programs.
        - simulator.
        - include file for smal.
        - smal.exe - see license for smal !
VHDL/
        - VHDL source of CPU.
        - VHDL testbench.
        - Memory files.
        - The testbench requires a simple sram implementation.
          I used this one: http://tech-www.informatik.uni-h ... imple/sram64kx8.vhd
          From the Hamburg VHDL archive (http://tech-www.informatik.uni-hamburg.de/vhdl/)

SMAL-source/
        - SMAL sourcode.

SIM-source/
   - WIN32 Simulator sourcecode. Porting to other platforms
     should be easy.

with it.

好东西问什么没人顶。

kata

哎，难道大家不怎么研究CPU IP核吗，这个铁没人理？！

Avalon

太贵了~~~

edwin512

处理器的东西很多啊
哈哈

beikong

好东东，受益匪浅啊！

mbit

支持一下！

mbit

先下载看看！

kata

我发的东东资料最全了，CPU核，例子代码，编译器到仿真器一应具全，还都带了源代码呐，文字说明也够详细了，版主干脆把这一贴加精吧！呵呵，
