Cobham Gaisler AB provides IP cores and supporting development tools for embedded processors based on the SPARC architecture. We specialize in digital hardware design for both commercial and aerospace applications
GR-MCC-C LEON Development Board
Actel ProASIC3E / ProASIC3L / RT ProASIC3 FPGA board, especially developed for LEON3 / LEON3-FT development, with on-board SRAM, Flash PROM, ADC devices, LVDS and CAN transceivers, user I/O expansion connectors etc.
The GR-MCC-C board has been developed in a co-operation between Cobham Gaisler, ÅAC Microtec and Pender Electronic Design, to support early development and fast prototyping of LEON3 / LEON3FT based designs. The board incorporates an Actel ProASIC3E field programmable gate array, and is capable of operating stand-alone or in combination with other boards.
Cobham Gaisler provides standard LEON3-FT based components based on the Actel RT ProASIC3 technology.
