Express Logic enhances ThreadX system

In addition to increased speed, ThreadX V5.2 includes features such as dynamic event filtering, expanded event trace, SMP enhancement and a reduction in global memory requirements.

Previously achieving a total of 6,928,383 iterations of the Thread-Metric message processing test, ThreadX V5.2 now realises 7,853,195 iterations.

With an overall ROM footprint as low as 2kbytes, ThreadX 5.2 reduces its minimal RAM requirements for global memory, bringing the minimal RAM requirement of ThreadX to 364 bytes.

This tiny footprint is ideal for SoC applications, where memory resources are limited and where ThreadX traditionally has been widely used.

All ThreadX architectures and tools now support Express Logic's TraceX graphical event analysis tool that helps developers visualise the behaviour of real-time systems.

ThreadX developers using Green Hills Multi development tools are no longer limited to Green Hills' Eventanalyzer, but can also now elect to use TraceX.

A particular set of events is often of interest to developers as they optimise an application.

Unfortunately, most event analysis programs log and display all events, including many that are irrelevant to a developer's current optimisation effort.

With ThreadX V5.2's ability to provide dynamic event filtering, each category of events can be enabled or disabled, allowing the developer to focus on a particular sub-set of events.

Event filtering reduces the clutter of unnecessary events, allowing more pertinent events to be logged and displayed, so developers are able to quickly find the most relevant information for the current investigation.

ThreadX V5.2 also introduces a generic SMP framework, making ThreadX more portable to multi-core environments.

The ThreadX/SMP version for the MIPS 34K takes advantage of this SMP foundation in ThreadX V5.2.
