速度与面积优化

通过资源复用和 RAM 映射实现改进

针对目标硬件，使用速度和面积优化从 MATLAB^® 函数生成满足时序和面积要求的高级综合代码。面积优化可减少设计的资源使用量。速度优化通过优化关键路径改进目标硬件上设计的时序，使设计以更高频率运行。

Map Persistent Arrays to RAM
Pipelining of for-Loops
Pipelining allows concurrent execution of multiple iterations.

Use the RAM mapping optimization in HDL Coder™ to map persistent matrix variables to block RAMs in hardware.

Generate HLS code from MATLAB code for Sobel filter.
