News Release from: Spirit DSP | Subject: 30-channel Sparse line echo cancelling solution
Edited by the Electronicstalk Editorial Team on 5 May 2003
Echo canceller runs on low-cost DSP
Spirit has developed an advanced version of its ITU G.168-compliant Sparse line echo cancelling solution, to be used mainly with T1/E1 lines
The Sparse line echo cancelling solution is a 30-channel G.168-2000 MIPS economy echo canceller version with CNG and tone disabler on a single TMS320VC5510-200 chip that increases cost effectiveness in comparison with existing hardware solutions. The solution performs automatic tail search and determines optimal compensated echo path (up to 128ms).

"The major advantage of Sparse line echo canceller over competitors is its unsurpassed hardware requirements, allowing to successfully cover $100 functionality on a $24 TI's C5510 chip and providing superior correlation between system requirements, quality and cost", said Spirit's CEO Andrew Sviridenko.
"The solution has a successful track record by being integrated in videophone products by one of the leading European communication companies, and now we are proud to provide a proven solution to the mass market to be leveraged by manufacturers".
The canceller's design allows tradeoff between MIPS consumption and echo path tail for each channel separately, achieved without code modification.

The solution is well suited for gateways and central office equipment, has a C-callable and re-entrant interface and an intuitive API.
The Sparse line echo cancelling solution consumes 5.6MIPS, 2.6Kword of program memory and 2.4Kword of data memory per channel, and functions mainly on 64 and 128ms echo tail.
The solution runs as a full-tap LEC solution with short tail length (16 to 32ms), while operating as Sparse in case of long tails.
Spirit's 30-channel Sparse line echo cancelling solution is available in the form of object codes for TI's C55x, and as C code that can be ported to other platforms.
