3.2
Major features of the RCPU include:
3.3
The instruction sequencer provides centralized control over data flow between execution units and register
files. It implements the basic instruction pipeline, fetches instructions from the memory system, issues
them to available execution units, and maintains a state history that is used to back up the machine in the
event of an exception.
The instruction sequencer fetches instructions from the burst buffer controller into the instruction pre-fetch
queue. The BPU extracts branch instructions from the pre-fetch queue and, using branch prediction on
unresolved conditional branches, allows the instruction sequencer to fetch instructions from a predicted
target stream while a conditional branch is evaluated. The BPU folds out branch instructions for
unconditional or conditional branches unaffected by instructions in the execution stage.
Instructions issued beyond a predicted branch do not complete execution until the branch is resolved,
preserving the programming model of sequential execution. If branch prediction is incorrect, the
instruction unit flushes all predicted path instructions, and instructions are issued from the correct path.
