LONDON Gaisler Research AB claimed that its microprocessor cores, specifically developed for aerospace applications, are gaining traction within GPS receivers as it announced a license agreement with Javad Navigation Systems Inc.
Javad (San Jose, Calif.) has signed a license to use the Leon3 microprocessor core and the GRLIB IP library in a combination GPS/Glonass positioning receiver, according to Gaisler Research (Gothenburg, Sweden). Javad was founded by Javad Ashjaee and has its R&D base in Moscow.
Gaisler Research, founded in 2001 by processor design engineer Jiri Gaisler, is a silicon IP licensor. Early versions of the Leon were made available on a royalty-free open-source license. It was while working for the European Space Agency that Jiri Gaisler developed Leon, a Sparc-compliant 32-bit processor, for which the design source code was made freely available. Gaisler now offers the Sparc v8-compliant Leon-2 and Leon-3 cores.
The Leon-4, expected to be available in the second half of 2007, is said to offer an improved pipeline and wider cache memories giving a performance increase of between 25 percent and 50 percent for a typical application at the same clock frequency when compared to Leon-3.
"Javad is now the fifth GPS company who is taking benefit of the LEON and GRLIB technology, giving high performance and low power consumption," said Per Danielsson, president and CEO of Gaisler Research. The Leon processor has previously been used for GPS receivers by companies such as Nemerix, Locsense, EADS Astrium and Semtech, Gaisler said.
