- astrange 6y agoThis is true for graphics/video codecs where you want to move around pixels in blocks smaller than 128-bit. The MMX instructions nobody likes in x86 are actually still pretty useful here. But you can do SIMD-in-GPR tricks, or dedicated hardware, or GPGPU to replace that, so it's not a big problem if it's missing.
- Narishma 6y agoI think even the old ARM11 in the first Raspberry Pi supported some SIMD-in-GPR features, though I'm not sure if software took advantage of them.
