    摘要: A system for processing a plurality of Equations includes a single full adder (44) which has the A input thereof multiplexed by multiplexer (62) and the B input thereof multiplexed by a multiplexer (94) and a multiplexer (66). The multiplexer (94) is operable to select a multiplicand for multiplication operations from a delay stack (54) for multiplication operations. The multiplication operation is performed by adding together partial products recording to Booth's modified algorithm. The partial products are generated by recode logic circuit (90) and (98). The recode logic circuits (90) and (98) are controlled by the multiplexed output from the multiplexer (80) which selects bits of a given multiplier stored in a K-stack (72). The multiplexer (62) in conjunction with the recode logic circuits (90) and (98) control reconfiguration of the adder (44) as a multiplication circuit. The addition operation is performed on the generated product by circulating the product back to the B-input of the adder (44) through the multiplexer (66). Data is selected from the output of a data stack (52) or from a D-register (108) which contains a prestored output value.

    摘要: High performance digital transistors (140) and analog transistors (144, 146) are formed at the same time. The digital transistors (140) include first pocket regions (134) for optimum performance. These pocket regions (134) are masked from at least the drain side of the analog transistors (144, 146) to provide a flat channel doping profile on the drain side. Second pocket regions (200) may be formed in the analog transistors. The flat channel doping profile provides high early voltage and higher gain.

    摘要: The device has a semiconductor chip having active circuitry in the face thereof. The circuitry has busing over it containing two conductive layers having a plurality of contacts and vias with spacings between them that alternate with respect to one another to provide current ballasting and improved switching uniformity. The spacings between the alternating contacts and vias provide regions of maximum conductor thickness and therefore reduces the busing resistance. Staggering the rows of alternating contacts and vias provides further current ballasting. A first conducting layer is used to contact and provide electrically isolated low resistive conducting paths to the various semiconductor regions while the second conducting region is used to provide selective contact to the first conductive layer, thus providing a means of busing large currents over active semiconductor area without sacrificing performance parameters.

    摘要: A lattice filter for processing lattice equations includes a fast adder (78) for adding partial products to partially perform a multiplication step. A full adder (44) is provided for completing the multiplication and then adding the product with a previously calculated and stored value. The input to the full adder (44) is multiplexed with a multiplexer (74) for selecting the sum output of the fast adder (78) and a multiplexer (76) for selecting the carry output of the fast adder (78). The multiplexer (74) also selects prestored values for addition with the summed output of the full adder (44). This summed output is selected by the multiplexer (76). The fast adder (78) sums partial products simultaneous with addition operations of the full adder (44). In this manner, the full adder (44) operates at a slower rate than the fast adder (78). Storage registers (58), (62), (70) are utilized to delay results output by the full adder (44) for later selection and operation thereon. These values are utilized as both the multiplicand the addend in subsequent operations. The multiplier is stored in a K-stack (90) and selected for the appropriate operations. A bit correction circuit (190) provides corrections for truncated bits in the form of a carry input to the full adder (44).

    摘要: A digital filter for synthesized speech includes a full adder (72) that is multiplexed to perform multiplication and addition/subtraction operations. The inputs of the adder (72) are multiplexed by multiplexers (90) and (92). The adder (72) calculates Y-values and B-values. The B-values are input to a delay stack (116) and the Y-values are stored in a Y-register (78). One product is generated of a multiplier stored in a K-stack (128) and a multiplicand selected by a multiplexer (122). The multiplicand is a prestored summation that was earlier stored in a sum register (82). This product is stored in an ACC register (74) and utilized in both the calculation of the B-values and the Y-values. Therefore, only one multiplication is required for corresponding Y- and B-values, thereby reducing the number of multiplication steps required in processing each stage of a digital filter.

    摘要: A digital lattice filter includes a Y-adder (44) and a B-adder (106). The Y-adder (44) calculates the Y-values for a linear predictive coding voice compression technique and the B-adder (106) calculates the B-values. Each of the calculated B-values output by the B-adder (106) is input to a B-stack (118) for storage therein. The B-stack (118) delays the B-values for one sample period. Multiplier constants are contained in a K-stack (90) for output to both adders (44) and (106) for use in the multiplication operation. The final value is stored in a Y1-register (104). Each of the adders (44) and (106) are multiplexed to perform a multiplication operation followed by an addition operation to generate the respective Y- and B-values. A generated Y-value is stored in a Y-register (56) for use in the next sequential Y calculation. In addition, the generated Y-value is used as a multiplicand for generation of a B-value. Therefore, it is only necessary to store the Y-values for one clock cycle and the B-values for up to nine clock cycles, thus reducing the amount of storage space necessary. In addition, the use of two multiplexed adders reduces the required processing speed at each of the adders.
