Abstract
An approach is provided in which a processor includes an adder that concurrently generates one or more intermediate results and a boundary indicator based upon instructions retrieved from a memory area. The boundary indicator indicates whether a collective result generated from the intermediate results is within a boundary precision value.
Claims25
A system comprising:
- a processor;
- one or more memories accessible by the processor, wherein the one or more memories stores one or more instructions;
- and
- an adder included in the processor that concurrently generates one or more intermediate results and a boundary indicator based upon one or more of the instructions, wherein the boundary indicator indicates whether a collective result generated from one or more of the intermediate results is within a boundary precision value.
1 more element
A computer-implemented method comprising:
- receiving one or more instructions at one or more processors;
- retrieving, by one or more of the processors, a first data value and a second data value corresponding to the received instructions;
- and
- concurrently generating, by one or more of the processors, one or more intermediate results and a boundary indicator based upon the first data value and the second data value, wherein the boundary indicator indicates whether a collective result generated from one or more of the intermediate results is within a boundary precision value.
1 more element
An information handling system comprising:
- one or more processors;
- a memory coupled to at least one of the processors;
- a set of computer program instructions stored in the memory and executed by at least one of the processors in order to perform actions of:
- receiving one or more instructions at one or more processors;
- retrieving, by one or more of the processors, a first data value and a second data value corresponding to the received instructions from the memory;
- and
- concurrently generating, by one or more of the processors, one or more intermediate results and a boundary indicator based upon the first data value and the second data value, wherein the boundary indicator indicates whether a collective result generated from one or more of the intermediate results is within a boundary precision value.
