Abstract: The present invention provides a method and apparatus for achieving m-bit.times.m-bit multiplication in two states with a minimum amount of hardware. The invention multiplies an m-bit multiplicand A by an m-bit multiplier B to produce a 2m-bit final product A.times.B. The multiplicand A has a most significant m/2 bits denoted by A.sub.H and a least significant m/2 bits denoted by A.sub.L. The multiplier B has a most significant m/2 bits denoted by B.sub.H and a least significant m/2 bits denoted by B.sub.L. By adding the least significant m/2 bits of B.sub.H .times.A.sub.L to the middle m/2 bits of the product B.sub.L .times.A, the invention produces a number having a least significant m bits that are the least significant m bits of the final product during a first pass. The most significant m bits of the final product are produced during a second pass. Using this technique, the invention produces the final product in two states with substantially less hardware than current systems.

Abstract: A new photoactive compound for use in the formulation of a photoresist comprises a bisphenol compound having an alkyl linkage substituted with a heterocyclic group. The new photoactive compound may be admixed with an alkali soluble resin to formulate a photoresist composition. The new photoactive compounds exhibit enhanced long term solubility in conventional photoresist solvents.

Abstract: Reconfigurable interrupt circuitry may provide differing interrupt output signals to various interrupt receiving devices which are adapted to be driven by interrupt circuits having differing drive characteristics. Control signals representative of the device characteristics of the interrupt receiving device are applied to the reconfigurable interrupt circuitry and output characteristics of the reconfigurable interrupt circuitry are selected according to the control signals. In this manner the reconfigurable interrupt circuitry may by adapted to drive interrupt receiving devices which are compatible with active high interrupt output, active low interrupt output, open drain interrupt output, totem pole interrupt output, tristate interrupt output and non tristate interrupt output.

Abstract: A new method for preparing commercially valuable polymeric ketones is described. The method employs an .alpha.-amiononitrile as a monomeric unit whereby an amorphous, soluble polymer having protected carbonyl moiety is obtained. Upon deprotecting the carbonyl moiety, a crystalline polymeric ketone is obtained. The method allows production of polymeric ketone materials having aromatic, aliphatic or mixed aromatic/aliphatic backbones.
