IEEE P1687: Toward Standardized Access of Embedded Instrumentation

The effort to standardize a methodology for accessing embedded instrumentation as IEEE P1687 continues to progress. This paper captures the current state of mind of the IJTAG Working Group with respect to the framework built to date and presents a discussion of other issues on which decisions are pending. The key elements of an architectural description language, a procedural language, and a hardware interface scheme are all taking shape, but still have many details to complete. Since this is a snapshot taken during the standard development process, the final form of the draft standard may differ from what is described here; any feedback to the working group is welcome.
