Complete Communications Engineering

Flexible and comprehensive C/assembly code-based solutions are available for a wide variety of general purpose and DSP processors (both commodity and SOC embedded processors). Competitive processor performance is achieved because of our considerable experience with code portability, compiler optimization and assembly implementation for these Commercial Off-the-Shelf (COTS) processors and other customer unique processors..

Through performance profiling and other VOCAL proprietary methods, hot-spot algorithms are identified which need to be implemented in fully optimized assembler in order to meet MIPS performance targets. Mixed C and assembly code generation is enhanced by VOCAL’s proprietary compiler pre-processing extensions. Our optimized software libraries are available for many different Operating Systems.

VOCAL also supports a variety of telephone line interface circuits including both FXS and FXO varieties which may be transformer isolated or solid-state depending on the customer application. Many of VOCAL’s reference designs use Mircochip LExxxx VoicePort SLIC/SLAC devices as well as designs based on Silicon Labs, Maxim and IXYS components. Additionally, hardware audio codecs from a number of manufacturers including TI and Wolfson/Cirrus.
