Processor promises cost
effective floating point
The latest SHARC floating-point processor from Analog Devices delivers almost a three-fold increase in megaflops per dollar over the nearest VLIW DSP competitor
The ADSP-21375, starting at $5, will allow engineers to use the precision of floating point processors in even the most cost-sensitive application areas. Offering breakthrough levels of 319MFLOPS per dollar, the new SHARC is ideal for a wide variety of applications such as mass market audio/video, industrial, and medical products.
'Thanks to our newest SHARC processor, DSP programmers will no longer need to trade off precision for price', said Jerry McGuire, General Manager, Convergent Platforms and Services Group, Analog Devices.
'Often times, on integer machines, programmers spend as much development time ensuring the numerical accuracy of their algorithms as they do in implementation'.
'Floating-point processing eliminates concerns of dynamic range and enables significant reduction of development time'.
'In addition, the $5 price point reduces system eBOM costs making the ADSP-21375 SHARC floating-point precision accessible to the broadest range of today's products and tomorrow's emerging applications'.
The ADSP-21375 floating-point processor combines the SHARC family's high-performance digital signal processing core operating at 266MHz with on-chip memory in an economical 208-pin QFP (quad flatpack) or BGA (ball grid array) package.
It also has 2Mbit of mask ROM and 0.5Mbit of internal RAM with direct execution from memory.
The ADSP-21375 is pin-compatible with other third-generation SHARC processors, enabling 'scalable performance' - customers gain the ability to spread development costs across multiple products based on a single platform design - reducing development time and maximising return on investment.
In addition, ADI supplies a range of development tools for SHARC processors to assist developers in getting their products to market faster.
Available tools include the Crosscore family, which encompasses the VisualDSP++ integrated software development environment and EZ-Kit Lite evaluation systems and emulators for rapid on-chip debugging.
For more than 10 years, SHARC has dominated the floating-point DSP market, delivering exceptional core and memory performance complemented by outstanding I/O throughput.
Starting at 319MFLOPS per dollar, the SHARC family makes floating-point processing economical for more applications.
For the highest performance multiprocessing, TigerSHARC processors deliver performance well above a billion floating-point operations per second.
1Gbyte/s multiprocessing link ports gluelessly connect multiple TigerSHARC processors and the 24Mbit of on-chip memory integrated onto each device.
