  • Patent number: 6507928
    Abstract: There is disclosed a cache memory for use in a data processor. The cache memory comprises a first static random access memory (SRAM) that receives up to N incoming bytes of data on an input bus and that stores the up to N incoming bytes of data in an N-byte addressable location. M incoming bytes of data may be written in each of the N-byte addressable locations during a write operation (where M may be less than N) and the M written bytes of data and N−M unwritten bytes of data are output from each N-byte addressable location on an output bus of the first SRAM during each write operation. The cache memory also comprises a parity generator coupled to the first SRAM that receives the M written bytes of data and the N−M unwritten bytes of data and generates at least one write parity bit associated with the M written bytes of data and the N−M unwritten bytes of data.

  • Patent number: 6504416
    Abstract: A number of voltage-controlled resistance cells, each formed by a transistor with a biasing capacitor connected between the gate and source and an associated controller coupled to the capacitor to maintain a steady charge on the biasing capacitor and keep the gate-source voltage at a control voltage corresponding to a desired resistance, are employed to form a voltage-controlled resistance structure. The gate voltage applied to each transistor is able to “float” together with the source voltage in order to keep the gate-source voltage constant, and the resistance structure exhibits improved voltage-dependent resistance linearity together with a larger range of biasing while lowering needed refresh frequencies to avoid noise injection.

  • Patent number: 6501284
    Abstract: Within a capacitive fingerprint detection device, finger detection is provided by a capacitive grid overlying the fingerprint sensor electrodes to measure the absolute capacitance of the finger placed on the sensor surface. The capacitive measurement is converted to a representative frequency, which is then compared to a reference frequency or frequency range to determine whether the measured capacitance matches the expected bio-characteristics of living skin tissue. The finger detection thus provides anti-spoofing protection for the fingerprint detection device.

  • Patent number: 6449710
    Abstract: The invention provides a method and system for performing instructions in a microprocessor having a set of registers, in which instructions which operate on portions of a register are recognized, and “stitching” instructions are inserted into the instruction stream to couple the instructions operating on the portions of the register. The “stitching” parcels are serialized along with other instruction parcels, so that instructions which read from or write to portions of a register can proceed independently and out of their original order, while maintaining the results of that out-or-order operation to be the same as if all instructions were performed in the original order. In a preferred embodiment, the choice of stitching parcels is optimized to the Intel x86 architecture and instruction set.

  • Patent number: 6421626
    Abstract: The present invention is a temperature sensor which is based on the actual temperature coefficients of a device in the circuit, rather than a predetermined threshold voltage that varies across different devices. This temperature sensor includes a circuit which determines the temperature of a device. More particularly, CMOS circuit is provided which uses a current source to generate charge and discharge voltages applied to a capacitor. These voltages are dependent on the temperature coefficient of a resistor in the current source. The charge and discharge times are then used to determine a frequency which is dependent on the temperature coefficient of the resistor. Thus, the temperature is sensed based on the output frequency of the circuit. Additionally, the present invention includes a mechanism which allows the temperature sensor to be activated or deactivated as needed.

  • Patent number: 6339028
    Abstract: An improved vacuum plasma etching device for plasma etching semiconductor wafers that have a photo-resist pattern. The improved plasma etching device has a reaction chamber in which the plasma etching is performed during a process cycle, an entrance vacuum loadlock for holding the next semiconductor wafer to be plasma etched, an exit vacuum loadlock for transporting the semiconductor wafers out of the reaction chamber after the plasma etching process, and a source of ultraviolet light. Exposing the semiconductor wafer to the ultraviolet light cures the photo-resist patterns, thereby improving CD dispersion, enhancing pattern transfer, and preventing photo-resist reticulation. Curing the photo-resist patterns while the semiconductor wafer is being held during the process cycle in the entrance vacuum loadlock, increases efficiency and productivity.

  • Patent number: 6317764
    Abstract: The invention provides a method and system for computing transcendental functions quickly: (1) the multiply ALU is enhanced to add a term to the product, (2) rounding operations for intermediate multiplies are skipped, and (3) the Taylor series is separated into two partial series which are performed in parallel. Transcendental functions with ten terms (e.g., SIN or COS), are thus performed in about ten clock times.

  • Patent number: 6298369
    Abstract: The high speed multiplier takes advantage of results from previous calculations by recognizing that in many cases the multiplicand between a first and second multiplication differs only slightly. Thus, the present system divides the multiplicand into a cache lookup bit (CLB) and a table lookup bit (TLB). The results of a first multiplication are stored in a cache. The CLB of a of the multiplicand in the second multiplication is then compared to the CLB of the multiplicand in the second multiplication. If the CLB matches, the product of the first multiplication is retrieved. The product of the TLB of the multiplicand and the multiplier is then retrieved from a lookup table and either added or subtracted from the retrieved product.
