ARM’s Technical Conference called TechCon™ is running between October 29th and 31st at the Santa Clara Convention Center in California.
This year I shall be making the trip over to present three classes:
- Can Existing Embedded Applications Benefit from Multicore Technology?
- Virtual Functions in C++ on the ARM Architecture
- Developing a Generic Hard-Fault Handler for ARM Cortex-M3/Cortex-M4
For those of you who are regular readers of this blog you’ll recognise the Generic Hard-Fault Handler from a previous post.
The class “Can Existing Embedded Applications Benefit from Multicore Technology?” came about as it seemed that not a day would goe by without an announcement of a major development in multicore technology. With so much press about multicore, I started to wonder whether I should consider using multicore technology in my typical embedded applications?
From a software developer’s perspective, however, all the code examples seem to demonstrate the (same) massive performance improvements to rendering fractals or ray-tracing programs. The examples always refer to Amdahl’s Law, showing gains when using, say, 16 or 128 cores. This is all very interesting, but not what I, and hopefully most embedded developers, might consider embedded. This class discusses multicore from a more traditional embedded viewpoint.
Many Embedded-C programmers still believe that C++ leads to slow, bloated programs. Though this viewpoint may have had limited foundation over a decade ago, it is misplaced for the core aspects of C++ (classes, inheritance, and dynamic polymorphism). With a modern ARM C++ cross-compiler, it is also misplaced for the more advanced features (templates and exception handling). In the class “Virtual Functions in C++ on the ARM Architecture”, I will be focusing on the performance and memory of the C++ virtual functions, type info and look at the use of multiple inheritance in an ARM embedded environment.
If you are planning to attend TechCon this year then please look me up. I will be making the presentations available via the blog after the event.
