Design and Implementation of GDI Accelerator

This paper designs and implements the accelerator circuit for Microsoft GDI AlphaBlend、BitBlt、MaskBlt、StretchBlt、TransparentBlt functions;Put forward a kind of efficient scale structure,improve the handling capacity of the images,after consider Data Dependence of Scaling algorithm.The FPGA output is in accordance with Microsoft GDI.Compared with Marvell PXA300 has obvious improvement in performance.In addition,the operating frequency can reach 203MHz with SMIC 0.13μm standard CMOS cell library using Design Compiler.
