This document describes how to hook up video devices such as the ADV7183 NTSC/PAL Video Decoder to the external bus of the ADSP-BF535 Blackfin Processor. It also explains the interface between the Blackfin processor and video devices. Contact information for technical support is provided.
This document explains how to connect video devices, specifically the ADV7183 NTSC/PAL Video Decoder, to the external bus of the ADSP-BF535 Blackfin Processor. Although the processor lacks a standard interface for video devices, it can receive video data in ITU-656 format via the Asynchronous Interface.
The guide details the basics of analog video composite signals and the decoding process within the ADV7183. It further describes the asynchronous interface of the ADSP-BF535, including how 32-bit data is fetched and the behavior of DMA-controlled data downloads split into bursts of eight read accesses.
