Overview

Intrinsics for moving values from vector data types to accumulator data types.

Moving data from vector data types to accumulator data types (e.g. for initialization) requires adjustment in precision because the accumulator data types are wider in size. For fixed point arithmetic, an appropriate left shift operation would align the decimal point between the two representations. The shift amount is specified as a parameter (in the range -1 to 62 which will be encoded as 0..63 in the instruction).

UPS/LUPS integer intrinsic functions

There are two variants of the UPS intrinsics based on width of input and output data types:

1. ups is used to convert integer
   • 8-bit vector data into corresponding 48-bit accumulator, or
   • 16-bit vector data (short) into corresponding 48-bit accumulator, or
   • 32-bit vector data into corresponding 48-bit accumulator
2. lups is used to convert integer
   • 32-bit vector data into corresponding 80-bit accumulator, or
   • 64-bit vector data (long) into corresponding 80-bit accumulator
