摘要
介绍了新一代智能存储片上系统SSC,详细讨论了SSC中NAND Flash子系统的软/硬件设计;采用基于模板的划分方法,实现NAND读写控制器的软/硬件划分。SSC已生产并通过工业测试。结果表明,采用软/硬件划分的方法,NAND控制器的面积比纯硬件的实现方法减小58%,性能仅下降16%;比单纯ARM软件实现,速度平均提高20倍,同时具有软件的高灵活性。
A new generation of smart storage SoC（SSC）was described. Hardware/software architecture of the NAND sub-system was discussed in detail. NAND Flash controller was partitioned by a template based hardware/ software co-design methodology. The SSC was manufactured and passed factory tests. Test results indicated that, by using hardware/software partitioning methodology,the area of the NAND controller was reduced by 58% ,while the performance decreased by only 16 %, compared with that of hardware implementation, and the average speed was 20 times faster, compared to that of ARM software implementation, while retaining its flexibility.
