MX86250 Description
INDEX MX86250 THE ADVANCED 64-BIT WINDOWS-95 AND DIRECTDRAW ACCELERATOR 1. INTRODUCTION The MX86250 is a new generation of fully integrated graphics and video accelerator. On a single chip, it integrates a 64-bit graphics CoProcessor, a true-color video processor, 135 MHz RAMDAC and dual programmable clock synthesizer.
MX86250 Key Features
- Uniformly accelerated graphics operations in all pixel formats : 256 color, High color and True color
- Optimized graphics engine for BitBLTs, rectangle fill, pattern fill, line draw, color expansion, text transfer, and clip
- Raster Operations (ROPs) with 3 operand BitBLT ALU
- One chip 8x8x24 pattern memory achieves highest thrughput in the most mon BitBLT in Windows- the Pattern BLT
- Deep on-chip Source and Destination FIFOs for sus tained burst cycles in BitBLTs
- Double buffered CoProcessor registers allows concur rent processing with CPU
- Built in Hardware cursor Extremely high bandwidth
- Achieves single clock cycle DRAM access in Graphics Processor, Video Processor and Display Processor
- Provides 400 MB/sec memory bandwidth using -50 EDO DRAM chips
- Even higher performance can be achieved by using
