Aspects of the invention include providing a trace pipeline in parallel to the execution pipeline, providing trace information on whether conditional instructions complete or not, providing trace information on the interrupt status of the processor, replacing instructions in the processor with functionally equivalent instructions that also produce trace information and modifying the scheduling of instructions in the processor based on the occupancy of a trace output buffer.

Abstract: A method and apparatus are provided for controlling instructions provided by a microprocessor output port to other execution units. A microprocessor pipeline of instructions is provided for each execution unit. These are scheduled via the microprocessor unit for each execution unit, a determination is made as to whether or not the execution unit can receive further instructions. If it cannot, it's associated pipeline is said to be stalled and instructions are deleted from the microprocessor pipeline. Its thread can then be restarted at a later time with the instruction corresponding to the instruction which was unable to execute.

Abstract: A method and system are provided for prioritising the fetching of instructions for each of a plurality of executing instruction threads in a multi-threaded processor. Instructions come from at least one source of instructions. Each thread has a number of threads buffered for execution in an instruction buffer 34. A first metric for each thread is determined based on the number of instructions currently buffered. A second metric is then determined for each thread, this being an execution based metric. A priority order for the threads is determined from the first and second metrics, and an instruction is fetched from the source for the thread with the highest determined priority which is requesting an instruction.
