动态参数模型确定SoC中异步FIFO深度的方法

针对超大规模集成电路和片上系统设计中确定异步FIFO浓度的问题,根据异步FIFO运行时的属性提出FIFO动态参数模型,该模型包括FIFO饱和度、写入端和读出端数据传输率及上溢/下溢频率。在该模型的基础之上,分析异步FIFO的深度与动态参数之间的关系,采用功能仿真方法确定片上系统中异步模块之间数据传输所需FIFO的深度。对典型实例的分析表明,采用这种方法能够在保证系统数据通信性能的前提下,获得最小的FIFO深度,优化系统资源的使用。

Aimmig at determining the depth of asynchronous first-in first-out(FIFO) in very large scale integrated(VLSI) circuits and system on chip(SoC) a model of dynamic parameters based on the running-time attribute of the asynchronous FIFO is presented in this paper.This model contains FIFO saturation,writing reading rate and overflow/underflow rat through the function simulation.On the base of this model,the depth of asynchronous FIFO in system on chip(SoC) can be determined by analyzing the relationship between...
