PORTING LEON3FT/GRLIB TO 4th GENERATION FLASH-BASED DEVICES

Cobham Gaisler develops the LEON3FT SPARC V8 fault-tolerant microprocessor that is available both as IP cores part of an IP library (GRLIB) that allows users to design their own custom system-on-chip (SoC) designs, and also as part of ready-made designs and devices. Cobham Gaisler has recently added support for Microsemi IGLOO2, and experimental support for Microsemi radiation-tolerant RTG4, devices to GRLIB. The presentation will give an overview of LEON processor system-on-chip architectures that are currently supported for the latest generation Microsemi devices and will provide an overview of the steps and obstacles in porting existing IP cores to these devices.
