摘要： A method and apparatus is disclosed that utilizes ''Lindsley's Law'', a polynomial convergence algorithm, suitable even for high convergence rates, to implement more efficient reciprocal j root, and hence, j root itself, computations of desired inputs. The invention emphasizes multiplication (114, 116, 118, 120), instead of addition, as the iterative operator, thereby reducing error at a rate relative to a power of a selected convergence rate.

摘要： A high-speed processor utilizes combinational logic and range limitation for a modified input value to increase efficiency in convergence factor determination for convergent division and square root computation. An input value (101) is modified to a value in a limited range (104), which is then partitioned into two subdivisions (106, 108). By utilizing these two groupings, the processing platform minimizes time consumption in conversion factor determination by inverting selected binary bits to form a modified factor (114) and utilizes that modified factor to facilitate high-speed convergence factor computation.

摘要： A method which utilizes a single preprocessing step (214, 216) to modify a divisor (D) in floating point division and to enable an exception correction and error checking operation (104, 108) to run concurrently with a division operation. The invention permits achievement of the correct predetermined result if an exception is present or the quotient if no exception occurs.

摘要： A method and a high speed processor (HSP) incorporating that method are set forth for processing signals representing outputs generated by remainderless division algorithms (102) and remainderless square root algorithms so as to obtain rounded outputs (112) conforming to the IEEE 754-1985 binary floating point arithmetic standard. The method and procedure of the present invention allow the solutions of floating-point computations to be rounded such that sign bits, as well as binary bits, of the rounded results are in full compliance with all guidelines of the stated standard.

摘要： A reliable method for terminating a telephone call is disclosed using a specific sequence of steps performed by hands-free control system. The invention requires that the call terminating command sequence be recognized as: two separate speech utterances (e.g., TERMINATE (158) and CONVERSATION (158)); in proper sequence (e.g. TERMINATE first, then CONVERSATION) with a maximum pause time interval (124) between the end of the first utterance and the start of the second utterance (e.g., 300 milliseconds) and which meet predefined speech recognition matching criteria (110). Moreover, the present invention provides the user with a procedure to continue the telephone call in progress should the speech recognizer make a false recognition or if the user did not intend to speak the proper command. As a result, present invention enables a user to disconnect a telephone call by voice command with a high degree of reliability, even under high ambient noise conditions.
