Wednesday, December 2, 2020
RVV 1.0 includes new instructions such as vector floating-point reciprocal and reciprocal square-root estimate for math calculation.
Key Points:
- RVV 1.0 includes new instructions such as vector floating-point reciprocal and reciprocal square-root estimate for math calculation.
- The NX27V was designed from ground up to be a Cray-like full vector compute engine.
- Its Vector Registers are as wide as 512 bits each and can be extended to 4,096 bits through LMUL setting.
- It supports RVV standard data types such as integer, fixed point, and floating-point as well as Andes-enhanced data types optimized for AI representations.
