Class KHRShaderFloat16Int8
VK_KHR_shader_float16_int8
extension allows use of 16-bit floating-point types and 8-bit integer types in shaders for arithmetic operations.
It introduces two new optional features shaderFloat16
and shaderInt8
which directly map to the Float16
and the Int8
SPIR-V capabilities. The VK_KHR_shader_float16_int8
extension also specifies precision requirements for half-precision floating-point SPIR-V operations. This extension does not enable use of 8-bit integer types or 16-bit floating-point types in any shader input and output interfaces and therefore does not supersede the VK_KHR_8bit_storage
or VK_KHR_16bit_storage
extensions.
Promotion to Vulkan 1.2
All functionality in this extension is included in core Vulkan 1.2, with the KHR suffix omitted. However, if Vulkan 1.2 is supported and this extension is not, both the shaderFloat16
and shaderInt8
capabilities are optional. The original type, enum and command names are still available as aliases of the core functionality.
