Texas Instruments Inc. (TI) has introduced the F28335 eZdspTM starter kit, which the company claimed makes it easy for engineers to evaluate and develop software on its new floating-point TMS320F2833x digital signal controllers (DSCs).

Now sampling, the F28335 controller is said to be the industry's first floating-point DSC, supplying developers of industrial systems with the inherent floating-point advantages of performance and simplified software development over fixed-point devices.

In addition to these digital processing solutions, TI offers engineers a broad portfolio of complementary analog solutions for development of greener variable speed motor control, digital power supplies and intelligent sensing applications.

The F28335 eZdsp starter kit, produced by Spectrum Digital Inc., a member of the TI DSP Third Party Network, is a standalone tool that provides developers a platform to easily develop software for the F2833x controllers. Only $495, this low-cost development platform provides all the hardware and software necessary for evaluation and software development, ultimately cutting design cycle time and associated costs.

The F28335 eZdsp comes complete with an F28335 target board, TI's Code Composer StudioTM Integrated Development Environment (ver3.3), universal AC power adapter and USB cable. The target board features the 150MHz/300MFLOPS F28335 DSC with 512Kbyte flash and 68Kbyte RAM, 128Kx16 off-chip SRAM.

Greener industrial apps
The simplified software development and performance boost common to floating-point processors offer better power efficiency for greener industrial applications. For example, the F2833x devices enable variable speed AC drives, which use one-eighth the energy compared to constant speed counterparts. The floating-point devices also enable clean energy through solar power inverters that more efficiently convert energy from photovoltaic panels.

The new F2833x floating-point controllers can increase performance by an average of 50 percent over TI's leading DSCs, while operating at the same 150MHz clock rate. Some algorithms, such as an FFT used for complex calculations, will see a 200-percent improvement over an equivalent 32bit fixed-point implementation.

Embedded software engineers typically prefer to design and prototype control systems in floating-point arithmetic, but final designs are usually implemented in fixed-point arithmetic. By removing the need to convert from floating point to fixed point, F2833x devices can save weeks or months of development time and eliminate the required modifications to scaling, saturation and adjustment of numerical resolution.

For industrial applications, TI also provides customers with a broad range of complementary analog solutions including high-performance data converters (ADCs and DACs), amplifiers, interface, low-power RF and power management products.

Developers can now order samples of the TMS320F28835 from TI or any TI authorized distributor. Samples of the F28335 are available in the 176-pin TQFP package and ready for delivery.

Developers can also place orders for the F28335 eZdsp kit today. The eZdsp will be available through TI distributors or at the TI Website. Shipments of the F28335 eZdsp kit will begin Oct. 15.
