To meet the mission requirements for projects beyond year 2000, the development of a more performant (+100 MIPS) processor denoted LEON was started in 1998. This paper presents the design goals and architecture of the LEON debug support unit, which provides unique capabilities for debugging and monitoring of complex applications.

DSU - Debug Support Unit To simplify debugging on target hardware, the LEON3 processor implements a debug mode during which the pipeline is idle and the processor is controlled through a special debug interface. The LEON3 Debug Support Unit (DSU) is used to control the processor during debug …

In addition to the cores described above it is recommended to include a LEON Debug Support Unit (DSU) and a debug communication link to be able to control the processor and inspect the system via the GRMON Debug Monitor. GRLIB contains several debug communication link (DCL) cores. All

This debug cores give you access to the internal AHB bus for read an write operations. There are special bus addresses with information about available IP cores. After reading the P&P area, you can debug the LEON3 processor through the Debug Support Unit.

The paper presents a case study on implementation of the fault tolerant LEON-3 processor system on a chip for space applications. The single-event upset (SEU) tolerance is provided by design. The technique applied detects and corrects up to 4 errors in the register file and caches. The implementation details and system-on-chip features are summarized.
