About This Guide
The
LogiCORE™ IP
Video Scaler v4.0 User Guide
provides information about generating the
Video Scaler core, customizing and simulating the core using the provided example
design, and running the design files through implementation using the Xilinx tools.
Guide Contents
This manual contains the following chapters:
•
Chapter 1, Introduction
introduces the Xilinx Video Scaler core and provides related
information, including recommended design experience, additional resources,
technical support, and submitting feedback to Xilinx.
•
Chapter 2, Overview

•
Chapter 3, Implementation
elaborates on the internal structure in the core and
describes interfacing.
•
Chapter 4, Video I/O Interface and Timing
describes how to drive the input timing
signals so the scaler can be operated correctly. It also describes the data output signals
and their relation to the output data.
•
Chapter 5, Scaler Architectures
describes Single-engine for sequential YC processing,
Dual Engine for parallel YC processing, and Triple engine for parallel RGB/4:4:4
processing.
•
Chapter 6, Control Interface
discusses the three control interface options available to
the user in CORE Generator™ software: EDK pCore, GPP and Constant.
•
Chapter 7, Scaler Aperture
explains how to define the scaler aperture using the
appropriate dynamic control registers.
•
Chapter 8, Coefficients
describes the coefficients used by both the Vertical and
Horizontal filter portions of the scaler, in terms of number, range, formatting and
download procedures.
•
Chapter 9, Performance
emphasizes the importance of available clock rate and
provides some worst-case conversion examples.
•
Appendix A, Use Cases
illustrates two likely usage scenarios for the video scaler.
•
Appendix B, Programmer Guide
provides a description of how to program and
control the data flow for the video scaler hardware pCore.
•
"
Appendix C, System Level Design
provides an example design extracted from a
known, working EDK project, including other Video IP blocks.
