Patent number: 7346048Abstract: A circuit and method are presented for signal processing and routing of digital voice telephony signals, using a specialized high-density integrated circuit voice processor. The voice processor performs several essential functions required for telephony processing, including echo cancellation, protocol conversion, and dynamic range compression/expansion. These functions are traditionally performed by multiple circuits or modules. By combining these capabilities in a single device, power and circuit board area requirements are reduced. The embodiment of the circuit and method disclosed herein include novel implementations of a time-slot interchange circuit and a telephony signaling circuit. Both of these circuits are designed to minimize demands on the signal processing engines incorporated within the voice processor, and account for very little of the on-chip circuitry.Type: GrantFiled: July 31, 2001Date of Patent: March 18, 2008Assignee: LSI Logic CorporationInventor: Danny C.

Publication number: 20080063013Abstract: A method of stabilizing an identification series of bits by iteratively reading the identification series and logical OR'ing the identification series with a mask string after each read of the identification series. This produces a mask string having a first value in all positions of the mask string where bits in the identification series have never changed value during all of the readings of the identification series, representing stable bits, and a second value in all positions of the mask string where bits in the identification series have changed value during at least one of the readings of the identification series, representing unstable bits. The number of the unstable bits in the mask string having the second value is counted, and a method failure code is selectively reported when the number of unstable bits exceeds a maximum allowable number of unstable bits. An identification string is produced from the stable bits, and an identification code is calculated from the identification string.Type: ApplicationFiled: September 11, 2006Publication date: March 13, 2008Applicant: LSI LOGIC CORPORATIONInventors: Danny C.
