Today Green Hills Software announced that it had ported velOSity to the Renesas SH726x. The port includes an impressive array of software, including:
A royalty-free RTOS
Middleware for TCP/IP stacks, file systems, graphics, and more
The MULTI IDE with optimized C/C++ compilers
Static code analysis tools
Advanced trace analysis tools
This port makes the SH726x a much stronger contender for media-processing applications. Although the SH726x is an MCU, its DSP performance is quite good. However, Rensas' tools were designed with MCU programmers in mind. As a result, the tools are missing several features critical to DSP software development, such as robust trace analysis. The velOSity port does a great job of addressing these shortcomings.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
