ANALOG DEVICES AN-524 ADV601/ADV611 Bin Width Calculation in ADSP-21xx DSP Application Note
This document explains how to use an Analog Devices ADSP-21xx family Digital Signal Processor (DSP) to control video compression in the ADV601 Video Codec chip. It details the design of the DSP to ADV601 interface and provides software for programming the DSP to manage the 'Bin Width Calculator' function.
The text describes the operation of the Bin Width Calculator, which adjusts 42 bin width and reciprocal bin width registers to achieve a desired compression ratio. It compares DSP-based versus host-based implementations, highlighting advantages such as real-time computation within the 1.2 milliseconds vertical retrace time and easier program development.
