可以看出,前文所述的融合结构round robin arbiter(F- MARX- RR)和传统解耦结构(RR and MUX)相比,拥有明显的低延时优势,原文中说可以至少降低8%的delay。 好吧也许你可能对这个数字有些失望,吹了半天怎么才8%,因为Giorgos太实在了,他在对照组(RR and MUX)中采用的round robin arbiter是业界最快的那个parallel ...

7.仲裁算法仲裁算法有固定优先级的仲裁(Fixedpriority),循环式优先级仲裁(RoundRobin),或是随机性的仲裁(Random)和竞争仲裁优先级(Tournament)固定优先级算法,就是指总线中各主设备的优先级是事先确定好的,在仲裁器仲裁过程中固定不变。 而循环优先级算法则不同,各主设备的优先级在仲裁器的仲裁过程中不是一成不...

上面这个Round Robin Arbiter的设计,好处就是思路简单明了,代码行数也很短,在你理解了Fixed Priority Arbiter之后,理解这个设计就很容易。但是这个设计也有缺点,即在面积和timing上的优化不够好。相比于我们接下来要介绍的设计,在request位数大(比如64位)的时候timing和area都要差一些,所以其实老李见并没有见到公司里...
