BEAVERTON, Ore.—(BUSINESS WIRE)—April 3, 2007— OCP-IP today announced the availability of a white paper discussing an approach to a standardized OCP-bus compliant debug interface. The proposed debug solution is an optional OCP port, implementing a Debug Interface Socket, which can be added to all cores and IP blocks to support a more uniform method of on-chip system analysis and access to embedded information at the core , multicore, and systems levels. The debug interface socket defines several layers of extended functionality to address the diverse and increasing debug needs for software, hardware, and mixed SoC prototyping and is intended to be compatible with other industry standards efforts addressing debug and related on-chip issues.
Work on the white paper was completed by the OCP-IP Debug Working
Group led by Texas Instruments, MIPS Technologies, and Pixelworks.
The document describes an overall debugging framework as the base
of the OCP debug interface. In the same way that the OCP data
framework is a functional superset for various bus interfaces and data
structures, the OCP Debug Framework defines an OCP Debug Interface
Socket that can connect to a superset of debug solutions, including
those developed outside of OCP-IP. The paper loosely defines
requirements and a set of debug signals at the OCP Socket and fabric
levels, which will be finalized later in 2007 after more testing and
prototyping, but leaves much of the specific options for
implementation open to IP and tools venders.
Commercial and licensable instrumentation IP and tools supporting
the many of the Debug Socket Interface options are available today
from OCP-IP members.
"Complex SoC adds new requirements and challenges in terms of
increasing visibility and debug control to a system, and standardizing
integration of hardware and software instrumentation into design
flows, and supporting emerging needs for architectures incorporating
complex network on chip buses, multiple cores, multithreading,
embedded security, power management and other issues are required "
said Ian Mackintosh, president and chairman of OCP-IP. "One goal of
the white paper is to open discussion on emerging needs in SoC design
that enables companies to offer a library of proven instrumentation IP
blocks and tools that address more complex debug situations and
purposes as part of the vast and ever expanding OCP infrastructure
available to our members."

The OCP International Partnership Association, Inc. (OCP-IP),
formed in 2001, promotes and supports the Open Core Protocol (OCP) as
the complete socket standard ensuring rapid creation and integration
of interoperable virtual components. OCP-IP's Governing Steering
Committee participants include: Nokia (NYSE: NOK), Texas Instruments
