Abstract
A fault detecting multi-thread pipeline processor with fault detection is operative with a single pipeline stage which generates branch status comprising at least one of branch taken/not_taken, branch direction, and branch target. A first thread has control and data instructions, the control instructions comprising loop instructions including unconditional and conditional branch instructions, loop initialization instructions, loop arithmetic instructions, and no operation (NOP) instructions. A second thread has only control instructions and either has the non-control instructions replaced with NOP instructions, or removed entirely. A fault detector compares the branch status of the first thread and second thread and asserts a fault output when they do not match.
