Embodiment Construction
[0144] figure 1 It is the general flow chart of the present invention, which mainly includes the following five steps:
[0145] 1. Divide linear assembly source program into non-storage basic block sequence SBB 1 ,SBB 2 ,...SBB N .
[0146] 2. Based on non-storage basic block sequence SBB 1 ,SBB 2 ,...SBB N , Construct the program control flow graph G (V, E).
[0147] 3. Based on the program control flow graph G (V, E), find all the loops in the program that can be compiled and optimized, and mark the non-storage basic blocks of these loops.
[0148] 4. Reinforce the program and add appropriate recalculation instructions and detection instructions for each non-storage basic block.
[0149] 5. Execute the hardened program to detect soft errors that occur at runtime.
[0150] Through the above five steps, the soft error detection of DSP linear assembler can be realized.
[0151] figure 2 Is the second step of the present invention based on the non-storage basic block sequence SBB 1 ,SBB 2 ...
