The Leon 3 licensible Sparc processor, developed by Gaisler
Research AB (Gothenberg, Sweden) has symmetric multiprocessing (SMP)
support, in the form of a port of the Linux 2.6 operating system, 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 32-bit 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.
