People still call ARM a “RISC” architecture despite ARMv8.3-A adding a FJCVTZS instruction, which is “Floating-point Javascript Convert to Signed fixed-point, rounding toward Zero”.
The fundamental issue that CPU architects run into is that the speed of light isn’t getting any faster. Even getting an electrical signal from one end of a CPU to the other now takes more than one cycle.
- vardump 7y agoNo idea why you've been modded down. Yeah, ARM arch is not that RISC anymore, there are a tons of instructions. Some pretty specific like that one. I don't see much of point of polarizing CISC vs RISC anymore in the first place. Both are borrowing from each other and gradually blending together.
