what's the difference between leon2 and leon2-ft? how can I get leon2-ft source code ?

abdelazeem201 commented 1 year ago

LEON2 processor core LEON2 has the following characteristics:

The GNU LGPL allows a high degree of freedom of intervention on the freely available source code. Configurability is a key project feature and is achieved through VHDL generics. It offers all basic functions of a pipelined in-order processor. It is a fairly sized VHDL project (about 90 files, for the complete LEON2 distribution, including peripheral IP cores)

LEON2-FT processor core

The LEON2-FT processor is the single-event upset fault tolerant (FT) version of the LEON2 processor. Flip-flops are protected by triple modular redundancy and all internal and external memories are protected by EDAC or parity bits.
