=== Description
|
|
|
|
The `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 pname:shaderFloat16 and
|
|
pname:shaderInt8 which directly map to the code:Float16 and the code: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 doesn't enable use of 8-bit integer types or 16-bit
|
|
floating-point types in any <<interfaces-iointerfaces, shader input and
|
|
output interfaces>> and therefore doesn't supersede the
|
|
`<<VK_KHR_8bit_storage>>` or `<<VK_KHR_16bit_storage>>` extensions.
