Synopsis

The Zve64x extension provides support for vector integer operations with a maximum element width (ELEN) of 64 bits. This is a base embedded vector extension that excludes floating-point vector operations.

Zve64x includes all functionality of Zve32x plus:

  • Support for 64-bit integer vector elements (SEW=64)

  • 64-bit vector load and store instructions

  • All vector integer instructions operating on 64-bit elements

Zve64x excludes all vector floating-point instructions and does not require implementation of the F or D extensions.

This extension is intended for embedded processors that need 64-bit vector integer operations but do not require floating-point support.
