AK7709VQ

Multi Core DSPs and SRCs

Description

The AK7709VQ is a highly integrated digital signal processor, including 8 stereo and 4 monaural sampling rate converters supporting sampling frequency up to 192kHz, a DIR, a DIT and two types of DSPs for Audio and Voice processing. The DSP1 and DSP2 support 491.52MHz operation clock and are optimized for C-language support. AKDSP1, AKDSP2, AKDSP3 and AKDSP4 have 10240 step/fs (when fs=48kHz) processing power. 
The AK7709VQ is able to process multiple sample rates simultaneously. This function is suitable for full bandwidth audio and voice processing, such as hands-free function along with audio. This simultaneous processing is enabled because the two types of DSPs can work on different but synchronized sampling frequencies. The AK7709VQ is a RAM based DSP, so it can be freely programmed for user requirements, such as acoustic effects and proprietary high-performance hands-free function.
