The CX20805 from Conexant is a products capture, analyze and render video and images for dual-core 32-bit, high-performance, low-power digital audio smart cameras used in automotive vision systems and smart processor targeted to applications with the most demanding video monitoring markets. In addition to capturing image audio requirements. Based on the Conexant Audio Processing and video information, CogniVue’s APEX technology enables Engine (CAPE) architecture with scalable performance of up to extraction of application-specific information from a scene 800 MIPS, the CX20805 integrates high-speed USB 2.0 and and interpreting the image data to make decisions or take other key audio interfaces with advanced power management action.
