基于仲裁的FPGA资源优化设计

Resource Optimization Design of FPGA Based on Arbitration

在现场可编程门阵列(FPGA)设计中,资源优化是十分必要的。复用是一种常用的优化方法,但有时简单的复用并不能满足实际的设计需求。从适当增加可复用模块的角度,提出了一种仲裁实现方案,在优化资源消耗的同时满足实际设计需求。该方法通过查询当前请求和可用资源,实现资源的使用释放循环,从而在时间上充分利用资源,提高资源使用率。

The resource optimization is necessary in field programmable gate array(FPGA)design.Multiplexing is a common optimization method,but sometimes simple multiplexing can't meet the practical design requirements.Considering adding the multiplex module appropriately,this paper proposes an arbitration realization method,which not only reduces the resource consumption,but also meets the practical requirements.By querying the current request and available resources,this method implements the resource occupation and release loop,which uses the resource sufficiently in time domain and improves the resource usage efficiency.
