Fault tolerant processor fits space-qualified FPGA
Gaisler Research has launched the Leon3 processor as a standard component using the space qualified and radiation tolerant Actel RTAX2000S FPGA.
The dataflow is handled through DMA channels; one for transmit and one for receive.
The Ethernet interface supports MII and GMII interfaces connected to an external PHY.
The MAC core also provides access to the MII management interface which is used to configure the PHY.
Some of the supported features for the DMA channels are scatter gather I/O and TCP/UDP over IPv4 checksum offloading for both receiver and transmitter.
Software drivers are provided for VxWorks, RTEMS, eCos, uClinux and Linux 2.6.
"The Leon3/GRLIB is widely used for network applications".
"The addition of a state of the art Gigabit Ethernet core will further strengthen GRLIB for these applications", said Marko Isomaki, Design Manager at Gaisler Research.
The Gigabit Ethernet IP is available for licensing now, either as a stand alone IP or as part of the GRLIB IP library.
The IP core is delivered as a synthesisable soft IP in VHDL source code together with test bench and software drivers.
