The GR-XC3S-1500 board is targeted especially to support the early development and fast prototyping of small Leon based systems, computer peripherals and as general purpose FPGA development environment.
Although suitable for general purpose Xilinx Spartan3 FPGA developments, the incorporation of on-board volatile and nonvolatile memory, together with serial, Ethernet, video DAC, USB 2.0 and PS/2 interfaces makes this board ideal for fast prototyping, evaluation or development of software for both LEON-2 and GRLIB/LEON-3 32-bit microprocessor designs.
The board incorporates a 1.5 million gate XC3S1500 FPGA device from the Xilinx Spartan3™ family, which is supported by the free Xilinx Webpack synthesis and place and route tools. The board is provided as a kit together with a power supply, JTAG programming cable, interface cables and CD Documentation including schematics and design examples.
The LEON microprocessor
The LEON processor is a synthesizable VHDL model of a 32-bit processor with an instruction set compatible with the IEEE-1754 (SPARC V8) . The Leon processor was initially developed to provide a high performance fault tolerant processor for space applications and is currently in use in European and international space programs. To enable development of system-on-a-chip (SOC) devices using the LEON core, the full VHDL source code is available both under the GNU GPL license and under commercial licensing conditions. The Leon core is available through Hitech Global.
