Hi all,
I'll like suggestions for this problem:
The problem is to detect the errors/faults in digital architectures
(different processors).Then, one of such modifications would be data
duplication, ie, the basic idea is to duplicate all the variables of
the program checking the consistency of the values. For each read
operation on a variable, the operation is repeated for the duplicate
variable and consistency control is done. If there is a difference
between the original value variable and duplicate value variable, then
an error is signal.
So when the program is presented to the compiler, for example in C
language, the idea is to make such alterations (as described above)
in the compiler so that it automatically makes the harden of the
program.
So, I would like to know how or where I could modify the compiler to
modify this statement as for example:
var = var/5 (high-level statement) how/where i could change, ie
reverse 1 bit of instruction, in this case would turn into another
statement and thus it is characterized as an error basculement bit.
I thought of beginning to work on the front end would be a
good/correct way, simply because the code in this stage is near the
source code.... i don't know if that makes sense .
Well, sincerly i feel lost if anyone has any suggestions ... thanks in
advance.
