Abstract: Embodiments herein describe integrity check techniques that are efficient and flexible by using local registers in a segment to store check values which can be used to detect errors in the local configuration data in the same segment. In addition to containing local registers storing the check values, each segment can include a mask register indicated which of the configuration registers should be checked and which can be ignored. Further, the segments can include a next segment register indicating the next segment the check engine should evaluate for errors.

Abstract: Methods and apparatus relating to transmission on physical channels, such as in networks on chips (NoCs) or between chiplets, are provided. One example apparatus generally includes a higher bandwidth client; a lower bandwidth client; a first destination; a second destination; and multiple physical channels coupled between the higher bandwidth client, the lower bandwidth client, the first destination, and the second destination, wherein the higher bandwidth client is configured to send first traffic, aggregated across the multiple physical channels, to the first destination and wherein the lower bandwidth client is configured to send second traffic, concurrently with sending the first traffic, from the lower bandwidth client, dispersed over two or more of the multiple physical channels, to the second destination.
