VOCAL has developed flexible and comprehensive C/assembly code-based solutions for a wide variety of platforms, including a diverse range of CISC, RISC and DSP processors (both commodity and SOC embedded processors). Among the solutions VOCAL has provided are modems, RAS servers, facsimile, fax over IP, VoIP CPE, VoIP servers, ATAs, VoIP speakerphones, IPBX, HPNA, voice and data RF communications, video surveillance and monitoring, government secure communication devices, medical devices, encryption, etc.
A partial list of Commercial Off-the-Shelf (COTS) processors supported include true DSPs such as ADI’s Blackfin and SHARC families, Texas Instrument’s 64x, 62x, 55x, 54x, Davinci and OMAP families, ARC and LSI DSP cores. General purpose CISC/RISC architectures such as PowerPC, PowerQUICC, x86, ARM, and MIPS, with or without SIMD and DSP acceleration instructions are also well supported.
VOCAL achieves its competitive processor performance because of its 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.
VOCAL also supports a variety of telephone line interface circuits. These include both FXS and FXO varieties which may be transformer isolated or solid-state depending on the customer application. Legerity VoicePort SLIC/SLAC devices used by many of VOCAL’s reference designs although equally supported are designs based on Silicon Labs, Teridian and Clare components. Designs have been provided for world-wide homologation and customized for specific operating environments.
