Intel® IPP Library 6.1 Fixes List

Intel® IPP Library 6.1 Fixes List

The tables below summarize specific customer issues or feature requests that have been addressed by the indicated product releases. Some items span multiple architectures and/or operating systems and some relate only to a single architecture or operating system.

NOTE: The issues, defects, bug reports, and feature requests summarized below represent specific issues with specific test cases. An item listed here does not imply that it necessarily applies to your application(s). If your situation does not match the specific test case you may not have experienced the error or problem associated with that update. It is not possible to describe the details of every issue and its specific test case in these tables.

Providing a complete description of each item in the list below is impractical. For that reason we ask that you post a message on the IPP user forum and reference this page and the "DPD" number of interest if you have further questions regarding the information in these tables. A DPD number with more information has a link.

These tables are updated regularly to correct errors and omissions.

NOTE: The bugs listed below are for both the IPP library and the IPP sample code. Always upgrade the IPP library and sample code at the same time.
