摘要

随着FPGA容量的增长,直接在FPGA上实现系统的内存部分和逻辑部分变得可行。我们认为这样的FPGA必须包含专门的架构支持,以便有效地实现存储器。这种体系结构支持的关键特性是,它必须足够灵活,以适应许多不同的内存形状(宽度和深度),并允许不同数量的独立寻址内存块。本文介绍了一种集中式现场可配置存储器体系结构,它由许多存储器阵列和用于组合这些阵列的专用映射块组成。我们还提供了一种比较这些体系结构的方法,并使用该方法来检查选择数组大小和映射块功能所涉及的权衡。

Architecture of Centralized Field-Configurable Memory
As the capacities of FPGAs grow, it becomes feasible to implement the memory portions of systems directly on an FPGA together with logic. We believe that such an FPGA must contain specialized architectural support in order to implement memories efficiently. The key feature of such architectural support is that it must be exible enough to accommodate many different memory shapes (widths and depths) as well as allowing different numbers of independently-addressed memory blocks. This paper describes a family of centralized Field-Configurable Memory architectures which consist of a number of memory arrays and dedicated mapping blocks to combine these arrays. We also present a method for comparing these architectures, and use this method to examine the tradeoffs involved in choosing the array size and mapping block capabilities.
