pulse EDITED BY FRAN GRANVILLE INNOVATIONS & INNOVATORS Floating-point-DSP family adds processors and software DSPs. The device increases clock speed to 1.25 GHz and is pin- and software-compati- ble with other members of the TMS320C66x family, providing an upgrade path from sin- gle-core configurations to two-, four-, and eight-core configurations. The company also has added features to the communications-centric TMS320C6670 SOC (system on chip). These features include a multistandard BCP (bit-rate coprocessor) and accelerators for PHY (physical)-layer processing in LTE (long-term-evolution), WCDMA (wideband-code-division-multiple- access), TDSCDMA (time-division/synchro- nous-code-division-multiple-access), and WiMax (worldwide-interoperability-for-micro- wave-access) applications. The 1.2-GHz, quad-core C6670 SOC targets use in SDRs (software-defined radios) in applications such as public safety and military radios, which require support for fewer users than cellular- radio base stations. The floating-point DSP also supports emerging applications for pro- cessing surveillance video in security and defense applications. TI also recently updated its MCSDK (multi- T core-software-development kit). The kit of software libraries provides Linux kernel support for the C66x DSP generation and the OpenMP API (application-programming interface) with a C66x compiler and runtime software for the KeyStone multicore archi- tecture. The MCSDK integrates a software- development platform that includes multi- core communication layers for intercore and interchip communication, validated and 12 EDN | MAY 26, 2011 exas Instruments has added the single-core TMS320C6671 to its TMS320C66x family of floating-point optimized drivers with TI's Sys/BIOS real- time operating system, and Linux support with appropriate demonstration examples. TI also plans this year to add to its DSPLIBs (DSP libraries) and IMGLIBs (image-process- ing libraries) for the C66x DSP instruction- set architecture with additional kernels and libraries for vision analysis, cryptography, voice, and fax applications. Texas Instruments offers the TMDX- EVM6670L and TMDXEVM6678L evaluation modules for the DSP family. The kits sell for $399 each and include a free MCSDK, a Code Composer Studio IDE (integrated develop- ment environment), and a suite of application and demo codes. The C6671 DSP, C6670 radio SOC, and evaluation modules are now available. The MCSDK is available as a free download. Prices for the C6671 DSP start at $79 (1000).—by Mike Demler ▷Texas Instruments, www.ti.com. TALKBACK "We replaced many IBM 1401 computers in those days of platform shoes, wide ties, loud sports jackets, and bell-bottom pants! I even had hair on top of my head back then. Today, I design entire microsys- tems that sit in the real estate that used to occupy a single flip-flop in a 0 6 U1005 computer!" —Engineer and self-described "migrant worker" Al Sledge, in EDN's Talkback section, at http://bit.ly/mG8Mjd.
