中文摘要：

设计实现了加速Microsoft GDI中AlphaBlend、BitBlt、MaskBlt、StretchBlt、TransparentBlt等函数的硬件结构;对函数实现中缩放算法的数据相关性进行研究,提出一种高效的缩放结构,与Marvell PXA300相比性能有明显提升.并且使用FPGA对本结构进行验证,结果与Microsoft GDI一致,在SMIC 0.13μm CMOS工艺标准单元库下使用Design Compiler进行综合,频率可达203MHz.

英文摘要：

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 203 MHz with SMIC 0 .13 μm standard CMOS cell library using Design Compiler .
