DSP SoCs feature
A/D convertors and Flash

Two new devices from Texas instruments combine high-performance DSP cores with high-precision analogue functions and Flash memory

The new mixed-signal 32bit DSPs, which offer 150MIPS, a single cycle 32 x 32bit MAC capability, up to a 256Kbyte of on-chip Flash memory and an on-chip 12bit ADC, make tangible TI's promised technology of late last year. The TMS320F2810 and TMS320F2812 are based on the C/C++ efficient 32bit TMS320C28x DSP core and are supported by a virtual floating-point math library that significantly eases the development of a multitude of applications.

The new devices address the growing need for increased DSP performance without sacrificing mixed-signal integration, combining on a single chip the best attributes of DSPs with those of microcontrollers.

By bringing the best of both worlds onto a single chip, the F2810 and F2812 DSPs provide new possibilities in a spectrum of applications, from traditional motor control applications to new markets, such as power supply and optical networking.

The TMS320F2810 and TMS320F2812 DSPs are code-compatible with TI's popular TMS320C24x DSP generation.

This broadens TI's TMS320C2000 DSP portfolio of processors ranging from sub-$2.00 up to 150MIPS performance.

With an unmatched level of integration, the F2810 and F2812 DSPs give designers a complete system-on-a-chip.

This greatly reduces board space and system cost and leads to simpler, more cost-effective designs.

The F2812 DSP integrates 128Kword of Flash memory and the F2810 DSP integrates 64Kword for simple reprogramming during development and in-field software updates.

Optimised event managers include PWM generators, programmable general-purpose timers and glueless capture encoder interfaces.

The devices also feature a 12bit ADC with a throughput of 16.7Msample/s and dual sample-hold providing critical support in tight control loops.

Five different on-chip standard communication ports provide simple communication interfaces to hosts, test equipment, displays and other components.

All C28x DSPs incorporate 32bit math capabilities and are supported by a unique IQ math library.

This combination allows designers to port floating-point algorithms to a fixed-point processor in a matter of minutes - faster than the laborious and time-consuming conversion of math algorithms in traditional 16bit devices.

TI's new DSPs give designers the math code efficiency of DSPs and the ease and system code efficiency of general-purpose processors, speeding the development process.

Further speeding this process, the F2810 and F2812 DSPs are supported by TI's eXpressDSP software and development tools, featuring Code Composer Studio host tools and the DSP/BIOS real-time kernel.

Code Composer Studio for the C2000 platform is available today and offers a fully integrated environment, which includes all the tools necessary to dramatically reduce the time needed to code, debug and tune a system based on the F2810 and F2812 DSPs.

An integrated and efficient C compiler, assembler and linker, coupled with an advanced editor, reduce the time needed to create compact and efficient code.

Also included is a powerful debugger and advanced profiler to provide the visibility needed to quickly debug and tune embedded control designs for optimum performance.

The F2810 and F2812 mixed-signal DSPs will soon be supported by DSP/BIOS, which slashes time-to-market by providing a complete set of instrumented kernel services optimised for fast execution speed.

It offers a priority-based scheduler along with a set of real-time analysis tools and the RTDX datalink between the host computer and the target DSP.

With these tools, the challenges of system design are easier to overcome, enabling designers to quickly meet critical deadlines.

As a part of TI's effort to provide unparalleled support at every step of the DSP design process, TI is introducing its TMS320F2812 Spectrum Digital eZdsp DSK to assist developers evaluating the F2810 and F2812 DSPs.

The eZdsp DSK is a platform to develop, demonstrate and run software for F2810 and F2812 processors.

Also, to simplify code development and reduce debugging time, the eZdsp DSK is fully compatible with the Code Composer Studio development suite.

This software toolchain provides the user with a C compiler, assembler, linker and Windows-based debugger.

Samples of the TMS320F2810 low profile quad flat pack (LQFP), TMS320F2812 microstar ball grid array (uBGA), and TMS320F2812LQFP DSPs will be made broadly available to the market though TI's distribution channel in July.

The F2810 is priced at $17.98 and the F2812 at $22.99 in 10,000-unit quantities.

The F2812 eZdsp DSK is available today for $305 via TI's distribution channels..
