Audio in Embedded Processors

In the world of microprocessor design, audio is a fascinating challenge that mixes quality, performance, time-to-market, and cost issues. The unique requirements of audio applications pose special challanges for processor designers, and create opportunities for system-on-chip developers who can integrate intellectual property to create custom solutions. At the March 8 meeting of the Santa Clara Valley Computer Society in cooperation with the Audio Engineering Society San Francisco Section, a panel of engineers will discuss their recent experience in audio solutions in embedded processors. They will address such issues as fixed point vs floating point implementation, speed vs code-size tradeoffs, and the benefits of embedded processor design. The panel discussion will be moderated by Gary Brown (Tensilica Inc) with panel participants Chuck Peplinski (Philips Semiconductor), Shree Paranjpe (Parthus Technologies), and Jeff Bier (Berkeley Design Technology Inc). Mr. Peplinski and Mr. Paranjpe offer the perspective of algorithm implementation, and Mr. Bier is uniquely qualified to address a wide range of DSP implementation issues.

Gary Brown currently works on audio implementations of user-customizable processors in Tensilica's Applications Group; he worked previously at Dolby Laboratories, managing the IC licensing and evaluation program, and at Matsushita Electric's Semiconductor Development Center in Osaka. He holds a B.S. in Engineering Mathematics and an M.S. in E.E.

Jeff Bier is co-founder and general manager of Berkeley Design Technology, Inc. (BDTI). At BDTI, Jeff oversees BDTI's technology analysis activities, which focus on the evaluation of processors, algorithms, and tools for DSP applications. Jeff is author or co-author of numerous reports and articles, including BDTI's "Buyer's Guide to DSP Processors" (now in its fifth edition). In addition, Jeff has been involved in developing communications software and implementing streaming media capabilities for products such as cellular phones and MP3 players. Jeff is a member of the IEEE Design and Implementation of Signal Processing Systems (DISPS) and Industry DSP (IDSP) Technical Committees.

Chuck Peplinski was born in Green Bay, Wisconsin. He received a B.A. in Physics from Pomona College, Claremont CA. Mr. Peplinski has been involved in the audio industry since his time as chief engineer at Pomona College's FM radio station. Mr. Peplinski has worked in software and hardware design for digital audio workstations, and wavetable audio engines for use in coin operated video games. Since 1996, he has been employed as audio section manager in Philips Semiconductors TriMedia project. There he has promoted the use of modular software libraries written in high level languages to support audio functions in consumer electronic products. Mr. Peplinski is a member of the AES, SMPTE, and IEEE.

Shreyas (Shree) Paranjpe holds a Bachelor of Applied Science in Engineering Physics from Simon Fraser University, Burnaby, Canada. He has worked as a DSP Engineer for a number of audio companies including Kurzweil Music Systems and Lexicon. He has researched, developed, and implemented music synthesis and effects algorithms as well as developed hardware architectures for audio processing. His interests include filter design and topologies, and psychoacoustics. Presently, he is an algorithm engineer for Parthus Technologies (San Jose, CA). He is a member of the AES and IEEE.

Directions

From 101 - Exit at Embarcadero Road heading west. As Embarcadero crosses El Camino Real it becomes Galvez Street. On Galvez, turn right at the first stop sign, onto Campus Drive. Follow Campus Drive to the first intersection and turn left onto Palm Drive. Follow Palm Drive as it circles past the main quad. Park in the visitor's lot on Palm Drive. Walk to the main quad to building 420

From 280 - Exit at Alpine Road heading east. At the first traffic light, turn right onto Junipero Serra Boulevard. At the next traffic light, turn left onto Campus Drive West. Follow Campus Drive until it intersects with Palm Drive, turn right onto Palm Drive. Follow Palm Drive as it circles past the main quad. Park in the visitor's lot on Palm Drive. Walk to the main quad to building 420.
