verilog实现: 格雷码计数可以用两种方式实现,一种是状态机,但是如果计数器的位数很大,比如6位,就得用至少64个状态,非常麻烦,另外一种方法是设计一个二进制计数器,通过它来计数,然后利用binary-gray的编码就可以得到对应的格雷码计数器。 还有一种方法,不是很常用,也很复杂,是通过组合逻辑直接产生格雷码的,而不需要...
If you’d like to brush up on implementing state machines in Verilog, you should read my article titled Creating Finite State Machines in Verilog. Encoding of States: Gray vs. Binary vs. One-Hot The three most popular encodings for FSM states are binary, Gray, and one-hot. Binary Encoding...
有限状态机编码对比 独热码(One-Hot Encoding) 很多独热码使用方法都是错的,没有起到简化译码的效果 独热码编码的最大优势在于状态比较时仅仅需要比较一个位 There are3 main pointsto making high speed state machines by one-hot encoding: Use 'parallel_case' and 'full_case' directives on a 'case ...
本文使用Verilog在DE2-70實現real time的binary image。 Introduction 使用環境:Quartus II 8.0 + DE2-70 (Cyclone II EP2C70F896C6N) + TRDB-D5M + TRDB-LTM Binary image是所有電腦視覺演算法的基礎,本文提供一個Binary module,供後續研究各種影像處理演算法使用。
