Leon processor supports Linux SMP

The Leon 3 licensible Sparc processor, developed by Gaisler Research AB, has symmetric multiprocessing (SMP) support, in the form of a port of the Linux 2.6 OS, the company said.

Linux 2.6 SMP is able to load balance applications across up to 16 Leon 3 cores automatically. It therefore enables developers to realize the performance and power consumption trade-off potential of multicore architectures while maximizing software reuse.

"We are proud to announce the Linux SMP support, which is yet another milestone for Gaisler Research. The Leon 3 and the GRLIB IP-library support up to 16 processor cores on the same AHB bus. The Linux SMP will enable straightforward software development for such advanced multicore systems," said Jiri Gaisler founder and CTO of Gaisler Research.

Gaisler developed Leon, a Sparc-compliant 32bit processor, for which the design source code was made freely available while working for the European Space Agency. He founded Gaisler Research in 2001 and continued to supply early versions of the Leon available on a royalty-free open-source license. Gaisler Research now offers the Sparc v8-compliant Leon-2 and Leon-3 cores.

The Sparc architecture is mandated for all European space projects and Leon is being deployed in a mix of aerospace, industrial and professional applications.
