Preventing Synergistic Processor Element Indefinite Stalls Resulting from Instruction Depletion in the Cell Broadband Engine Processor for CMOS SOI 90 nm

Application Note
Under some circumstances, the use of a branch hint instruction can cause a Synergistic Processor Element (SPE) to stall indefinitely. SPE instruction prefetch can be interfered with in such a way that an SPE can run out of instructions to execute and make no further progress, while remaining in the RUN state.
