Abstract: A method and system for an infrastructure for performance-based chip-to-chip stacking are provided in the illustrative embodiments. A critical path monitor circuit (infrastructure) is configured to launch a signal from a launch point in a first layer, the first layer being a first circuit. The infrastructure is further configured to create an electrical path to a capture point. The signal is launched from the launch point in the first layer. A performance characteristic of the electrical path is measured, resulting in a measurement, wherein the measurement is indicative of a performance of the first layer when stacked with a second layer in a 3D stack without actually stacking the first and the second layers in the 3D stack, the second layer being a second circuit.

Abstract: A method, system, and computer program product for performance-based chip-to-chip stacking are provided in the illustrative embodiments. A first candidate chip is selected from a set of candidate chips for stacking, each candidate chip in the set of candidate chips including an integrated circuit. A part of a 3D performance determinant is activated in the first candidate chip. A value of a performance parameter is measured for a set of operating conditions. A stacked performance value is computed for the first candidate chip using the value. A subset of the set of candidate chips is stacked in a stack, the subset including the first candidate chip, such that a combined value of the performance parameter for the subset when stacked in a first order is within a defined range of values for the performance parameter.

Abstract: A method for maintaining cache coherency for a multi-node system using a specialized bridge which allows for fewer forward progress dependencies. A local node makes a determination whether a request is a local or system request. If the request is a local request, a look-up of a directory in the local node is performed. If an entry in the directory of the local node indicates that data in the request does not have a remote owner and that the request does not have a remote destination, the coherency of the data is resolved on the local node, and a transfer of the data specified in the request is performed if required and if the request is a local request. If the entry indicates that the data has a remote owner or that the request has a remote destination, the request is forwarded to all remote nodes in the multi-node system.

Abstract: A method for maintaining cache coherency for a multi-node system using a specialized bridge which allows for fewer forward progress dependencies. A look-up of a local node directory is performed if a request received at a multi-node bridge of the local node is a system request. If a directory entry indicates that data specified in the request has a local owner or local destination, the request is forwarded to the local node. If the local node determines that the request is a local request, a look-up of the local node directory is performed. If the directory entry indicates that data specified in the request has a local owner and local destination, the coherency of the data on the local node is resolved and a transfer of the request data is performed if required. Otherwise, the request is forwarded to all remote nodes in the multi-node system.

Abstract: Pressure regulators find uses in a variety of applications such as, for example, pneumatic tools, water systems, and paintball markers. Pressure regulators may substantially benefit from a separate seal carrier adapted to facilitate maintenance, improve performance, and open independent of piston movement; poppet bypass bores to increase regulated fluid flow; and, an outlet poppet adapted to operate independent of the piston.

Abstract: A method of reducing power consumption while maintaining performance characteristics and avoiding costly over-design of a high-speed communication link embedded in an SOC is provided. The method includes synthesizing the communication link at a reduced voltage to determine and isolate circuitry that is supply-voltage-critical from circuitry that is non-supply-voltage-critical. The supply-voltage-critical circuitry contains components that may not operate at the reduced voltage without degrading the performance characteristics of the communication link. A non-reduced voltage is used to drive the supply-voltage-critical circuitry while the reduced voltage is used to drive the non-supply-voltage-critical circuitry. The reduced voltage is generated using a voltage regulator embedded in the communication link.
