Architectures with instructions tailored to speed up signal processing and other mathematical operations, e.g. polynomial evaluation, bit-reversed addressing for fast Fourier transforms, hardware circular buffer support, repeat-multiply-accumulate instructions, hardware FIR filter support, etc.
C simply doesn't know about any of these operations, so the compiler never uses the instructions. |
