write signal 中文意思是什麼
write signal
解釋
記錄信號-
By changing of the difference of write address and read address, a delayed signal from read port is achieved. the two methods have different idea but reach the same goal and have the properties that are pure digital delay, little error, compendious circuit and maneuverability
兩種方法異曲同工，為純數字延遲，具有抗干擾性強、誤差小、電路簡明，可操作性強等優點，既體現了設計的多樣性，又體現了fpga設計的靈活可編程特性。 -
