Webinar: Optimizing the performance and portability of multicore DSP platforms with a scalable programming model supporting the Multicore Association’s MCAPI®

When: Tuesday June 26, 2012 at 9am PDT

The demand for increased performance and evolving multicore DSP capabilities poses challenges to developers’ realizing the potential of multicore platforms while maintaining portability and scalability. This webinar presents a solution for achieving multicore entitlement. The presenters demonstrate how to ‘instantly’ apply MCAPI® to a flexible system design, utilizing a graphical user interface to simplify and visualize the topology and inter-process communication strategy.

MTAPI® and TIWG Updates

The MTAPI® specification draft is currently being reviewed by the working group. We will soon be looking for external (non-member) reviewers to help in our final review process. Please send me an email if you are interested in becoming an MTAPI® reviewer.

The Tools Infrastructure Working Group is working on definition of a service framework and associated protocols to enable Multicore tools connectivity. This framework will allow tools to discover and connect to arbitrary services on multicore systems that may have greatly varied topologies. Initial services planned include trace control and data collection (building on our previous work on the Common Trace Format) as well as debug integrating the GDB open source debugger as an exemplary implementation.

Upcoming Events

MCA President, Markus Levy, will present at the 12th International Forum on Embedded MPSoC and Multicore. His presentation, entitled “"Extracting the Value of Multicore in Smartphones" will be given on July 11th.

At the Tracing Summit 2012, Aug. 30th, San Diego (, Mathieu Desnoyers will present "Interoperability Between Tracing Tools with the Common Trace Format (CTF)". This presentation introduces new technologies and a common format allowing tracing of Linux systems at the software (hypervisor, kernel, user-space), and hardware levels. One major building block of CTF is the Trace Stream Description Language (TSDL) which flexibility enables description of various binary trace stream layouts. It enables tracing of Linux deployed on multi-core CPUs, interacting with DSPs, where each of these components exports its own trace streams. This presentation covers work on the the Common Trace Format (CTF) specification and its reference implementations: the Babeltrace trace converter, the LTTng 2.0 kernel tracer, and the LTTng-UST 2.0 (user-space tracer). This work has been realized in collaboration with Ericsson, the Multicore Association Tool Infrastructure Workgroup and the Linux Foundation Consumer Electronics Linux Forum (CELF) Workgroup.
