  • System signalling schemes for processor & memory module
    Patent number: 6584588
    Abstract: A computer system includes a main processing unit (12) coupled to a DSP/memory module (40). The DSP/memory module (40) includes semiconductor memory (42) and digital signal processor circuitry (44) including one or more digital signal processors (56). The DSP/memory module (40) may be placed in standard main memory sockets, such as a SIMM or DIMM sockets, and used as conventional main memory. The memory module can also be used in a smart mode, wherein the digital signal processor (56) performs operations on data for retrieval by the main processing unit (12).
    Type: Grant
    Filed: October 30, 2000
    Date of Patent: June 24, 2003
    Assignee: Texas Instruments Incorporated
    Inventors: Basavaraj I. Pawate, Matthew A. Woolsey, Douglas L. Mahlum, Fred J. Reuter, Yoshihide Iwata, Judd E. Heape

  • Temperature sensor and method
    Patent number: 5501637
    Abstract: A direct, noncontact temperature sensor includes an ellipsometer (104-106) to determine absorptance for layered structures and a pyrometer (102) to determine emissive power and combines the two measurements to determine temperature.
