Synopsis

The Zve64f extension adds single-precision vector floating-point support to the Zve64x base embedded vector extension. The maximum element width (ELEN) is 64 bits, supporting both 64-bit integer and 32-bit floating-point elements.

Zve64f includes all functionality of Zve64x and Zve32f plus:

  • Single-precision vector floating-point instructions with 64-bit integer support

  • Support for widening floating-point operations up to 64-bit integers

Zve64f requires the F (single-precision floating-point) extension.

This extension is intended for embedded processors that need 64-bit vector integer operations and single-precision floating-point support.
