SUMMARY OF KEY POINTS
. Graphical state machines are much easier to read and allow for automatic
speed/area optimizations.
. Of key importance is the readability of the top level of abstraction where
the design takes place. Of less importance is the readability of the autogenerated RTL.

. Some abstract design tools such as Synplify DSP allow for automatic architectural trade-offs such as pipelined versus folded implementations.

. Understanding the criteria for partitioning a design between hardware and software will be a requirement of system engineers into the foreseeable future

静态随机存储器（SRAM）静态随机存储器（SRAM）是一种广泛用于计算机系统和嵌入式设备中的高速随机访问存储器。与动态随机存储器（DRAM）不同，SRAM 不需要定期刷新，因此可以实现更快的访问时间和更低的功耗。SRAM通常用于缓存、高速缓冲器和存储器应用程序中，其中性能和可靠性至关重要。阅读详情
