Analog Devices introduced a 200-MHz version of its ADSP-BF592 Blackfin embedded processor that delivers 400-MMAC performance for $1.99 each (in 1,000-unit quantities). The 200 MHz version achieves a BDTImark2000 performance score of 1120 and a BDTImark2000/$ performance/cost score of 562 compared with the 400 MHz version’s BDTImark2000 score of 2240 and BDTImark2000/$ score of 747. Featuring active power draw as low as 51 mW and a 9 mm x 9 mm 64-lead LFCSP package, the new 200-MHz Blackfin BF592 model makes integrating high-performance DSP (digital signal processing) desirable for many power and cost-constrained applications in the industrial, medical, video, audio and general-purpose markets. Target applications include portable healthcare products, audio devices and imaging products, such as CMOS-sensor-based 2-D barcode scanners. Its peripheral set includes two SPORT’s, a PPI, two SPI’s, four general-purpose counters and a factory-programmed instruction ROM block containing the VDK RTOS and C-runtime libraries.
