MindSpeed Technologies, Newport Beach, CA

Mar 1999 to Apr 2002

Systems Engineer (Voice Systems Integration Group, Multi Service Access

Division)

Responsibilities:

. Was a part of a team that worked towards understanding the software

and hardware architecture of the Countach, which is a DSP, an integral

part of the CSMV12 - Anyport Anydata communication product of the

company

. Worked on mapping the code for different speech coders from CSMV12 to

Miro (C64), tasks included mapping of the code while retaining the bit-

exactness. Optimization of the mapped code followed for all the speech

coders

. Worked on the development of Adaptive Multi-Rate Speech (AMR) Codec.

This codec maps input blocks of 160 speech samples in 13-bit uniform

PCM format to encoded blocks of 95, 103, 118, 134, 148, 159, 204 and

204 bits and from these encoded blocks to output blocks of 160

reconstructed speech samples. The coding scheme is the so-called

ACELP, Algebraic Code Exited Linear Prediction Coder

. Developed the full Countach assembly code for the AMR speech encoder

and decoder including the Voice Activity Detector (VAD) and

Discontinuous Transmission (DTX) algorithms from the ETSI Standards

. Effectively optimized the AMR speech codec Countach code to reduce the

Millions of Instructions Per Second (MIPS) number. Went through

several passes of optimization to achieve the desired MIPS

. Efficiently measured the channel density of the AMR codec on the

CSMV12-A12 channel AnyPort AnyData communication product of the

company

. Developed the Binary Image (BIM) and passing of the built-in Self-Test

(BIST) in order to measure the channel density

. Completed the development and optimization of the G.726 Adaptive

Differential Pulse Code Modulation (ADPCM) speech codec encoder and

decoder. This codec does conversion of 64 kbits/s channel to/from a

16, 24, 32 or 40 kbit/s channel using the ADPCM coding technique

. Developed the Countach assembly code from the ITU-T Standards and

effectively transferred the G.726 ADPCM code on the CSMV12 hardware

platform and successfully ran 16 channels on the board along with

other algorithms such as echo-canceller, tone-detectors and generators

. Assisted in developing a non bit-exact version of the code for the

G.726 and optimized it which resulted in running at least 40 channels

on the hardware along with other algorithms.
