Blackfin DSP targets telecommunications and Internet appliances

21 November 2001 DSP, Micros & Memory

Analog Devices is sampling the ADSP-21535 Blackfin DSP. The ADSP-21535 is a highly integrated, high performance 16 bit DSP and, according to the company, is the world's first DSP to deliver the Micro Signal Architecture jointly developed with Intel. It also includes dynamic power management, which throttles the power consumption of the DSP as the performance requirements of the application change. Operating at 300 MHz, the ADSP-21535 delivers 600 MMACS (million multiply accumulate operations per second) for applications in telecommunications and a wide range of Internet appliances.

The company has also announced a $10 version of its Blackfin DSP. The ADSP-21532 sets a new price-performance benchmark, delivering 300 MHz of performance to consumer applications. It integrates on-chip voltage regulation to simplify board design and reduce total system costs, and also integrates specialised audio (I2S) and video (CCIR-656) interfaces. This makes it particularly useful in consumer/professional audio and handheld/portable video applications.

The Blackfin DSP architecture combines high performance 16 bit dual MAC signal processing functionality with ease-of-use attributes found in general-purpose microcontrollers, says ADI. Programmable in C and C++, Blackfin DSPs efficiently execute both signal processing and control code. They are supported by Crosscore, Analog Devices' range of DSP software and hardware development tools. The VisualDSP++ Integrated Development Environment facilitates code development by providing a compiler, cycle-accurate simulator, debugger and statistical code profiling tool under a single user interface.

Two speed versions of the ADSP-21535 are offered. The ADSP-21535PKB-300 operates at 300 MHz (600 MMACs) and the ADSP-21535PKB-200 operates at 200 MHz (400 MMACs). The ADSP-21532 operates at 300 MHz, integrates 640 Kb of on-chip SRAM, and is packaged in 160-lead MBGA package.
