A comparison of ARM vs RISC-V Vector Extensions #RISCV #ARM @ARM
Microprocessor with vector instructions is going to be the big thing for the future. Why? Because self-driving, speech recognition, image recognition are all based on machine learning and machine learning is all about matrices and vectors.
We have been banging our heads in the wall trying to eek out more performance for years ever since we semi-officially declared Moore’s laws to be over. In the golden old days of microprocessor design, we could simply double the clock frequency of the CPU each year and boom everybody was happy. That wonderful old trick is over.
All of the tricks really boil down to one central idea: Trying to find ways of doing work in parallel.
SIMD instructions such as Neon, MMX, SSE2 and AVX have worked great in multimedia applications. Doing things like video-encoding e.g. But we need to to squeeze out more performance in more areas. Vector instructions offer a lot more flexibility in taking almost any loop and turning it into vector instructions. However there are lots of different ways of going about this.
ARM and RISC-V actually follow a profoundly different strategy. See how – read more in the article here by Erik Engheim.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
