The ADSP-21477 offers a very low power and high performance processor, 200 MHz/1200 MFLOPs in an 88-Ld LFCSP package. The low power architecture of the ADSP-21477 makes these products particularly well suited to address the automotive audio and industrial control market segments where low power is a requirement. In addition to its high core performance, the ADSP-21477 includes additional processing blocks such as FIR, IIR and FFT accelerators to increase the total performance of the system. There is a new feature called variable instruction set architecture (VISA) that allows the code size to be decreased by 20% to 30% and increase the memory size availability. The fourth generation DSP allows the ability to connect to external memory by providing a glueless interface to 16-bit wide SDR SDRAMs.
