  • Publication number: 20130220421
    Abstract: Apparatus and methods are described using asphaltene and its derivatives as semi-conducting materials in photovoltaic cells. Asphaltene is used in an organic PV device as either or both of a p-type material and/or n-type material. The asphaltene-based material can be treated such as by de-metalization, metal addition, extraction, fractionation, and optimization of the asphaltene material. Treatment can be selected to create an asphaltene-based material having pre-selected characteristics, such as absorption value, reflectance, index of refraction, band gap, etc. The asphaltene-based materials can be blended or otherwise combined with inorganic or non-asphaltene organic materials. Further, asphaltene material can be used as an interfacial layer in the PV device.

  • Patent number: 6209083
    Abstract: An FPU configured to operate in normal and fast modes. In normal mode, floating point instructions are stalled in an address calculation unit of the processor until the previously issued floating point instruction has cleared the FPU, thereby indicating that the previous floating point instruction will not have an exception. In fast mode, the address calculation unit will issue a next floating point instruction to the FPU, where it is held in a 4-deep instruction queue, regardless of whether a prior instruction has cleared. By eliminating stalls in the instruction execution pipeline caused by floating point instructions being held in the address calculation unit pending clearance of the prior floating point instruction, the instruction execution pipeline may issue floating point instructions to the FPU at a faster rate.

  • Patent number: 5689721
    Abstract: A method of detecting anomalous overflow conditions is used, in an exemplary embodiment, in implementing in a 486-type microprocessor, nonrestoring two's complement division for negative quotients using 2n bit dividends and n bit divisors. Each interative division step, an adder/subtractor is used to add/subtract the properly aligned divisor to/from the left shifted dividend, to produce a partial remainder and a carry out bit Cout. Complement Cout is assumed to be the same as the most significant bit of the partial remainder PR(MSB), such that PR(MSB) is used as the sign bit in further computations, with complement Cout being used to control quotient generation according to DVRS XOR Cout. The anomalous overflow test signals overflow when complement Cout is the different than the most significant bit of the first partial remainder PR1(MSB), such that the anomalous overflow test is implemented according to the logic equation: Cout XNOR PR1(MSB).

  • Patent number: 5428622
    Abstract: A scan test architecture includes first and second serial scan paths for transferring test data to and from an integrated circuit's logic. A first clock controls transfer of information on the first scan path and a second clock controls transfer of data on the second scan path. The first and second clocks are alternately enabled by a control signal initiated under program control of the external test system.

  • Patent number: 5420989
    Abstract: A coprocessor 18 comprises a bus controller 24 which further comprises a primary bus controller 28 and a secondary bus controller 30 that drive a floating point processor core 26. The primary bus controller 28 comprises a memory mapped bus interface 32 for processing memory mapped format instructions and an I/O bus interface 34 for processing conventional I/O format instructions. The primary bus controller 28 remains essentially transparent for execution of I/O format instructions and translates memory mapped format instructions into sequential bus cycles compatible to an I/O bus interface for processing conventional I/O format instructions, and for execution by the floating point processor core.

  • Patent number: 5144570
    Abstract: A normalization circuit (24) which comprises a signed digit subtracter (25) coupled to operand registers (14, 19). The signed digit subtracter (25) subtracts the operands and inputs a signed digit difference to a pseudovalue converter (27). The pseudovalue converter (27) generates a pseudovalue in non-redundant format which contains its most significant non-zero bit in the selected bit position. The pseudovalue is output to a leading zero counter (28) which counts the number of leading zeroes in the pseudovalue.

  • Patent number: 5040138
    Abstract: An arithemtic circuit (10) which comprises an adder/rounder circuit (20) and a normalization estimation circuit (24) coupled in parallel to operand register (14, 19). A signed digit subtracter (25) subtracts the operands and inputs a signed digit difference to a pseudovalue converter (27). The pseudovalue converter (27) performs a three-bit overlapping scan of the signed digit differene to determine a bit location which corresponds to the approximate bit position of the most significant non-zero bit in the result of the arithmetic process performed in adder/rounder circuit (20). The pseudovalue converter (27) generates a pseudovalue in non-redundant format which contains its most significant non-zero bit in the selected bit position. The pseudovalue is output to a leading zero counter (28) which counts the number of leading zeroes in the pseudovalue. The number of leading zeroes is output to a barrel shifter (16) via an L-bus (30).
