摘要:
In a computer system having multiple components, a bidirectional scheme which allows bidirectional data communications between components over a single wire without using termination resistors by placing two drivers from two corresponding processor cores on the same wire, and allowing simultaneous data transfer in two directions. This doubles the effective bandwidth per pin without requiring a modification to the clocking scheme of the system. The driver is impedance matched to the line, and used as the termination for the driver on the opposite end of the wire. This reduces the termination power, since no power is consumed when both drivers are in the same state. The bidirectional flow of data creates a ternary encoding, with a relatively simple decoding possible.

A daisy chained clock distribution scheme for distributing a clock signal from a central communications clock driver to the nodes of a massively parallel multi-processor computer or supercomputer. The daisy chained clocking scheme is implemented using point-to-point clock distribution of a differential clock signal to the communication nodes of a plurality of processors in a multicomputer system or to components connected to a common bus in a high speed microprocessor system. Differential signaling is employed wherein the differentiality is maintained including through silicon. In an alternate embodiment, the clock pulse is also regenerated in each node component.

摘要:
According to embodiments of the disclosed subject matter, cores in a many-core processor may be periodically tested to obtain and/or refresh their dynamic profiles. The dynamic profile of a core may include information on its maximum operating frequency, power consumption, power leakage, functional correctness, and other parameters, as well as the trending information of these parameters. Once a dynamic profile has been created for each core, cores in a many-core processor may be grouped into different bins according to their characteristics. Based on dynamic profiles and the grouping information, the operating system (“OS”) or other software may allocate a task to those cores that are most suitable for the task. The interconnect fabric in the many-core processor may be reconfigured to ensure a high level of connectivity among the selected cores. Additionally, cores may be re-allocated and/or re-balanced to a task in response to changes in the environment.

摘要:
An extraction system detects a voltage stored in a capacitor and then extracts energy from the capacitor when the voltage falls below a predetermined value. The capacitor may be an ultracapacitor formed in silicon or another semiconductor material, and the predetermined value may equal or be based on a minimum operating voltage of a load driven by the ultracapacitor. Once the energy is extracted, the system converts the energy into a voltage sufficient to continue driving the load. Energy extraction may be performed by a variety of circuits including a linear regulator, a switched capacitor voltage converter, an adiabatic amplifier, and a DC-to-DC boost converter. The system may further include a monitoring circuit which detects dynamic changes in the converted ultracapacitor voltage over to maintain the operating voltage of the load.
