FPB (Flash patch breakpoint)
The FPB unit:
•
implements hardware breakpoints
•
patches code and data from code space to system space. This feature gives the
possibility to correct software bugs located in the Code Memory Space.
The use of a Software Patch or a Hardware Breakpoint is exclusive.
The FPB consists of:
•
2 literal comparators for matching against literal loads from Code Space and remapping
to a corresponding area in the System Space.
•
6 instruction comparators for matching against instruction fetches from Code Space.
They can be used either to remap to a corresponding area in the System Space or to
generate a Breakpoint Instruction to the core.
