The LEON3FT-RT3PE processor is a SOC design based on LEON3FT core, implemented in the RT ProASIC3 radiation-tolerant FPGA. The processor is delivered as a RT ProASIC3 device, with several package and quality options. The combination of the RT ProASIC3 radiation-tolerance and the fault-tolerant capabilities of LEON3FT makes LEON3FT-RT3PE suitable for space application.
LEON3FT-RT3PE RT ProASIC3 functionality
In addition to the LEON3FT core, the LEON3FT-RT3PE includes a number of application-specific IP cores. Several pre-define configurations are available to address different application requirements. All configurations have the same basic architecture, which includes the following functions:
The configurations are differentiated according to same the table as LEON3FT-RTAX.
Performance and power
The configurations can be clocked up to 25 MHz over the full military temperature range (except LEON3FT-RT3PE-IC1 and LEON3FT-RT3PE-SC1 that are fixed to 24 MHz). This provides upto 20 DMIPS and 4 MFLOPS in configurations with an FPU. The power consumption depends on the application, and is typically 0.2 W at full processor load. In power-down mode, the processor power consumption is ~ 0.1 W.
In addition to the pre-defined configurations, it is possible to order LEON3FT-RT3PE devices with custom configurations. Such configuration can also include IP core from the GRLIB IP library which are not listed above. An NRE cost will be charged for the development of each custom configuration.
