Techniques to determine integrity of information
First Claim
Patent Images
1. A method comprising:
- receiving an instruction to generate an integrity validation value over a portion of contents of a source buffer;
utilizing a retrieve capability of a data mover to retrieve at least a portion of contents identified in the instruction; and
determining an integrity validation value over a portion of the source buffer based on the instruction, wherein the instruction further comprises an instruction to compare at least a portion of the determined integrity validation value with a comparison value.

Abstract
Techniques are described herein that may utilize capabilities of a data mover in order to determine an integrity validation value or perform an integrity checking operation. The integrity validation value determination and integrity checking operations may be controlled by descriptors or instructions. In some implementations, integrity validation value determination and the integrity checking operations may include determination of a cyclical redundancy checking (CRC) value.
