Publication number: 20230048717Abstract: A method of performing instruction marking in a computer processor architecture includes fetching instructions from a memory unit by a fetching unit in the computer processor architecture. Instruction groups for marking are determined. Fetched instructions are matched to instruction groups for marking. The fetched instructions are marked. Some of the marked instructions are selectively unmarked. The marked and unmarked instructions are forwarded to a queue of instructions for processing in the computer processor architecture.Type: ApplicationFiled: August 4, 2021Publication date: February 16, 2023Inventors: Shricharan Srivatsan, John A.

Patent number: 10060681Abstract: A heat pipe augmented passive solar space heating system modulates the temperature inside a building structure, particular during heating seasons when the ambient temperature is below levels customarily associated with adequate room comfort, and in some embodiments comprises a solar absorber, a heat pipe surrounding wholly or partially by insulation, the heat pipe having three main sections which are an evaporator at one end proximal to the solar absorber, a condenser at the other end proximal to an interior room being heated, and a rubber adiabatic section between those. Additional aspects such as a mechanical valve in the adiabatic section are disclosed to limit unwanted thermal gains when cooling is needed because the ambient temperatures already exceed room comfort.Type: GrantFiled: September 21, 2016Date of Patent: August 28, 2018Assignee: UNIVERSITY OF LOUISVILLE RESEARCH FOUNDATION, INC.Inventors: M. Keith Sharp, Brian S. Robinson

Patent number: 7089406Abstract: A method and apparatus for controlling program instruction completion timing for processor verification provides, alternatively or in combination, an improved simulation technique and/or processor in which resource allocation as well as other performance-specific scenarios can be stressed over typical operating conditions by controlling the completion timing of one or more program instructions. A high-level program controlling simulation of a VHDL model of a processor can simulate extension of the completion time of a predetermined instruction in order to hold the instruction in the execution and completion queues, placing an effective hold on the resources allocated for the instruction. Alternatively, the VHDL model may include logic for controlling completion timing of the program instruction by using a processor clock cycle counter. Verification testing of actual processor hardware may be facilitated by including the counter and associated control logic within production or prototype processors.Type: GrantFiled: June 9, 2003Date of Patent: August 8, 2006Assignee: International Business Machines CorporationInventors: John Martin Ludden, Darin Marcus Greene, David A. Schroter, Wallace Keith Sharp

Such multipliers are particularly suited to resolving signals in a first set of axes into signals in a second set of axes where other signals are available which are combinable to give trigonometric functions required to translate between the first and second sets of axes.Type: GrantFiled: September 19, 1974Date of Patent: June 15, 1976Assignee: Ferranti, LimitedInventors: Kenneth Robson Brown, Colin Keith Sharp
