摘要： An apparatus for equalizing grants of a primary bus to a plurality of primary devices and secondary devices is provided. The apparatus comprises a primary bus bridge to arbitrate grants of the primary bus among a plurality of primary devices attached to the primary bus and a secondary bus bridge to arbitrate grants of the primary bus among a plurality of secondary devices attached to a secondary bus. A logic device is also provided to equalize grants of the primary bus to the primary and the secondary devices.

摘要： Mechanism for accurately measuring useful capacity of a processor allocated to each thread in a simultaneously multi-threading data processing system. Instructions dispatched from multiple threads are executed by the processor on a same clock cycle. A determination is made whether Time Base (TB) register bit (60) is changing. A dispatch charge value is determined for each thread, and added to the Processor Utilization Resource Register for each thread when TB bit (60) changes.

摘要： Redundant time-of-day (TOD) oscillators are aligned, within a master oscillator path, to local logic oscillator and used to create independent step-sync signals. A step checker validates and provides selection signals to identify which of the TOD oscillators operates according to a criterion. Independent step-sync signals are transmitted to several sibling chips. Local step and sync signals are delayed to arrive at TOD register nearly synchronous with TOD registers in sibling chips. A slave oscillator path may be used to select time signals generated in a sibling chip, whereby the master oscillator path is deselected. A primary control register set may be used to configure which among several chips is a master chip using the master oscillator path. All remaining chips are slave chips. All segments of the topology are redundant. One of multiple possible alternate topologies is defined in a secondary control register set. Commands and TOD values are passed on the fabric at predefined time increment boundaries to establish, restore, or maintain synchronization across all chips.

摘要： A method and apparatus are provided for reducing the number of cycles required to checkpoint instructions in a multi-threaded microprocessor that has dispatch group checkpointing. A determination is made in a first stage of a checkpoint pipeline whether checkpointing can occur for a group of instructions. The results of processing the group of instructions flow to a second stage of the checkpoint pipeline regardless of whether the group of instructions is ready to checkpoint. If the group of instructions is ready to checkpoint, the group of instructions is checkpointed in a third stage of the checkpoint pipeline.
