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： Techniques for accounting microprocessor resource consumption. The present invention provides an automatic method to timely determine the current microprocessor clock frequency. Information provided by timer facilities of the microprocessor is reused by sampling this information at constant intervals. Such direct derivation of the microprocessor clock frequency is a real-time method that also takes into consideration secondary effects. Examples for such secondary effects include clock frequency variations across chips due to manufacturing variations, any degradation due to performance loss by thermal, or other detrimental effects as well as any voltage changes. In the preferred embodiment of the invention, the real-time microprocessor clock frequency determination is implemented as part of the microprocessor itself. No additional service processors or other external hardware facilities are needed in order to control the microprocessor clock frequency determination function.

摘要： The present invention relates to system clocking in computer systems. In particular, it relates to system clocking in high-end multi-processor, multi-node server computer systems with an enhanced degree of performance and reliability and to a method for dynamically switching between a first and a second clock signal, if the first should fail. More redundancy even to the Dynamic Clock Switching Circuit (DCSC) (14) and the wiring (17) from there to multiple, PLL-(12) free clock chips (22) is provided. Instead of only one DCSC (14) and one single wiring (17), two of them (14-0, 14-1; 17-0, 17-1) are used combined with a further particular logic present on each clock chip (22), which in combination generate two synchronous, fine-tuned, minimum-shifted clock signals and select always the first of them to arrive at a FlipFlop controlling the output for clock distribution wiring.

摘要： A computer system is provided which includes a plurality of nodes, which include chips of different types. In each node, one of the chips is configured as a master chip, which is connected to one or more slave chips via two or more multi-drop nets (e.g., checkstop, clockrun). The master chip and the slave chips are connected to a reference clock, and event triggering information is transmitted via the multi-drop nets (checkstop, clockrun) to the slave chips. Event trigger commands are submitted by the master chip when it receives a request, and internal offset counters are used to adjust both the receiving cycle and the cycle when the command is propagated to the units on the chips. In operation, the offset counters are synchronized by a reference clock.
