这几天希望能在Spartan系列新品xc6slx16csg324-2运行带有FFT的软核处理系统,基本系统早就搭建好了.需要做的就是建立一个封装有Xilinx提供的FFT IP的自定义外设.由于Xilinx提供的FFT模块直接是用AXI Stream的接口. 在XPS下,Create or Import a Peripherel,选择使用AXI Stream的接口,而非以前常用的AXI4-lite接口.然后选择使用Verilog语言,允许生成模板,允许自动建立一个ise工程,Stream的字

With multi-frequency clocks being used in today’s devices, it's necessary to switch the source of a clock while the device is running. 1 Problem The two clock frequencies can be totally unrelated to each other or they can be multiples of each other.
A method of handling processor to processor interrupt requests in a multiprocessing computer bus environment is described. This method allows a multiple-tiered, increasing priority, interrupt request scheme. This method also allows processor to proce
Given the expansive growth in the field, it's become challenging to discern what belongs in a modern computer science degree. My own faculty is engaging in this debate, so I've coalesced my thoughts as an answer to the question, "What should every co
