摘要： 介绍了现代数码产品中NANDFlashMemory控制器的基本控制和4种软硬件划分不同的控制器设计。作者用VerilogHDL语言分别实现了这4种不同的控制器的,并进行了硬件面积、DSP占用率和接口灵活性的量化比较,指出了各种方案适用的范围。通过对一个SOC项目的需要分析,设定了基准函数,从而选出了合适的软硬件划分方案。

Abstract: The article introduces the NAND flash memory controller used in modern digital products and gives four kinds different software/hardware partition solutions. These controllers are implemented in Verilog HDL and quantitatively compared in hardware area, DSP core time and interface flexibility. Through the analysis of one SOC project, the metrics are given and the property of software/hardware partition is chosen.
