摘要

To improve executing efficiency of 2D graphics operations ,a parallel processing accelerator for typical 2D graphics , image and text was proposed .Functional verification and performance evaluation were carried out on FPGA prototype system constructed using Xilinx Virtex6 xc6v1x760 .As a result ,compared to Marvell PXA300 ,the accelerating engine has an obvious improvement on accelerating 2D graphics operations .Compared to software rendering ,when 2D graphics operations are executed on the accelerating engine ,it can be speeded up by 23 times on average .Its operating frequency can reach 325 MHz using SMIC 65nm CMOS technology ,which meets design requirements .%为提升二维图形操作的执行效率，提出一种并行计算结构的二维图形加速引擎，能够同时对典型的二维图形、文本和图像进行处理，显著增强二维图形图像的处理效率。基于Xilinx Virtex6 xc6v1x760构建FPGA原型系统，进行功能验证和性能评估，评估结果表明，相比Marvell PXA300，该二维图形加速器能更加有效地加速二维图形操作，CPU 使用硬件调用在加速引擎上执行二维图形操作比软件执行平均快23倍，在SMIC 65nm CMOS工艺下，加速器的工作速度可达325 M Hz ，满足设计需求。
