glitch:毛刺,glitch-free clock switching circuit:无毛刺时钟切换电路,今天讨论的主题就是如何实现时钟的无毛刺切换,本文将从有毛刺的时钟切换电路、无毛刺的源同步时钟切换电路、无毛刺的异步时钟切换电路三方面展开。 有毛刺的时钟切换电路: 之前曾在降低功耗相关的一篇推送中讲到过时钟使能信号:时钟使能降低功耗,当时...
无毛刺的时钟切换英文名叫:Glitch-free clock switching circuit,不要把 Clock Domain Conversion当成了时钟切换,傻傻地设计了半天答非所问。 Clock Domain Conversion为跨时钟域传输问题,就是最常考也是经常听到的CDC问题(应该会有专门的总结)。 今天的主题是Glitch Free Clock Switching: 就像这样: clk0和clk1是无...
An apparatus for compensating for glitch occurrence in a reset signal that is applied in an integrated circuit, includes: a logic stage capable to process an incoming signal and a delayed incoming signal that is a delayed version of the incoming signal, the logic stage capable to generate an ...
一道简单的笔试题_时钟切换电路(Glitch-free clock switching circuit)由一道 某科笔试开始,如下: 解析:电路功能:两个异步时钟源切换电路; DFF1和DFF3作用:在选择路径插入一个上升沿触发器,用于缓存数据…
A circuit, including a state machine, e. g. a logic array and a set of controlled storage devices, receives conditioning signals, such as reset, power failure signals and signals fed back from the storage devices, and uses the signals to determine which of a number of clock sources is to...
无毛刺的时钟切换英文名叫:Glitch-free clock switching circuit,不要把 Clock Domain Convers... 从秋招的经验来看,Verilog设计类的题目,如:奇偶分频,状态机,序列检测,波形产生,跨时钟域处理,门控时钟,同步FIFO,格雷码与二进制码转换,异步复位同步释放,时钟切换,异步FIFO等,其中最为复杂的恐怕属于时钟切换了吧。
Variable input delay method: Raja in[1] proposed variable input delay method which involves insertion of “permanently on” series transistor at the input of logic gate for glitch free digital circuits. 解决峰值瞬态IR-Drop 最常用的方法是在芯片中撒入去耦电容 ( Decap cell ), 这些Decap 充当局部电...
A glitch free clock switching circuit includes a first enable synchronization logic that generates a first clock enable in response to a first enable from a first enable generation logic. The clock sw
FIG. 4b is a circuit diagram showing the high speed glitch-free transition detection circuit with disable control of the present invention. DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG 4a we show now a high level view of the principle components of this present invention. Logic Section...
