  Modified Goertzel Algorithm in DTMF Detection Using the TMS320C80 DSP
  PDF, 101 Kb, File published: Jun 1, 1996
  This document presents a modified Goertzel algorithm for DTMF tone detection on a TMS320C80 ('C80) 32-bit multiprocessor digital signal processor (DSP). The algorithm detects the incoming frequency with an offset range plus or minus 1.5%. For this application, a basic implementation is provided, but additional testing is required to make this detection algorithm complete. The appendix provides the

  Acoustic Echo Cancellation Algorithms and Implementation on the TMS320C80
  PDF, 223 Kb, File published: May 1, 1996
  Acoustic echo cancellation on the TMS320C8x multiprocessor digital signal processor (DSP) offers high performance and flexibility to meet varying user needs. This document describes the implementation of an integrated N-tap digital acoustic echo canceller on the TMS320C8x parallel processor (PP). A brief discussion of a generic echo cancellation algorithm is provided. A 512-tap (64-ms span) echo

  TMS320C8x System-Level Synopsis (Rev. B)
  PDF, 516 Kb, Revision: B, File published: Sep 1, 1995
  The TMS320C8x is Texas Instruments? first generation of single-chipmultiprocessor digital signal processor (DSP) devices. Asingle ?C8x contains up to five powerful, fully programmable pro-cessors:a master processor (MP) and up to four parallel proces-sors(PPs). The MP is a 32-bit RISC (reduced instruction setcomputer) processor with an integral, high-performanceIEEE-754 floating-point
