CVT16 instruction set
Encyclopedia
The CVT16 instruction set, announced by AMD
on May 1, 2009, is an extension to the 128-bit SSE
core instructions in the x86 and AMD64 instruction set.
CVT16 is a revision of part of the SSE5
instruction set proposal announced on August 30, 2007. This revision makes the binary coding of the proposed new instructions more compatible with Intel's AVX
instruction extensions, while the functionality of the instructions is unchanged.
The CVT16 instructions allow conversion of floating point
vectors between single precision and half precision.
The CVT16 instruction set is supplemented by the XOP
and FMA4 instruction sets, which were also included in SSE5.

Floating point
In computing, floating point describes a method of representing real numbers in a way that can support a wide range of values. Numbers are, in general, represented approximately to a fixed number of significant digits and scaled using an exponent. The base for the scaling is normally 2, 10 or 16...
