| 內(nèi)核的部分都沒有視頻教程，只有文字表達，后面的外設(shè)跟驅(qū)動什么的再看視頻教程吧，這一篇簡單說說MSA。
MSA全稱Multiply-Accumulators，看圖說話：
The two multipliers (MAC0 and MAC1) perform fixed-point multiplication and multiply and accumulate operations.
Two identical MACs
- Each can perform fixed point multiplication and multiply-and-accumulate operations on 16-bit fixed point input data and outputs 32-bit or 40-bit results depending the destination.
Functions
- Multiplication
- Multiply-and-accumulate with addition (optional rounding)
- Multiply-and-accumulate with subtraction (optional rounding)
- Dual versions of the above
Features
- Saturation of accumulator results
- Optional rounding of multiplier results
下一章是SHIFTER，全稱：BARREL-SHIFTER
