Fundamental differences between the ADSP-21xx DSPs and Blackfin processors are: 1. ADSP-21xx is a 16-bit fixed-point, single-MAC DSP ONLY, while Blackfin is a 16-bit fixed-point, dual MAC processor with an embedded 32-bit RISC MCU instruction set and four 8-bit Video ALUs. 2. ADSP-21xx DSP speeds range from 50MHz to 160MHz, whereas Blackfin processors run up to 600MHz. 3. Blackfin processors offer Dynamic Power Management and lower power consumption over ADSP-21xx DSPs. 4. Blackfin processors have a compiler and tool suite much more tuned for High Level Language support like C/C++. Blackfin processors are neither source nor object code compatible with ADSP-21xx processors. However, if you are an ADSP-21xx DSP user, you’ll find that the Blackfin processor instruction set resembles the ADSP-21xx family in terms of its algebraic nature, but it adds microcontroller functionality as well.
