摘要
本文阐述了视频α混合IP的设计和实现方法。为了改善电路的性能,在设计中不仅采用了双通道和流水线技术,而且结合FPGA芯片的结构特点,采用了许多针对性的电路,并充分使用了FPGA上的DSP运算模块。此IP性能较高,且具有一定的通用性;它已经在两款FPGA系统中得到了成功应用,这对其它电路设计具有一定的借鉴意义。
This paper described FPGA design of Alpha-Blending IP. In order to improve the performance, double data channels and pipelining technology were adopted in the design. And many special circuits and DSP blocks of FPGA were used fully according to the feature of FPGA chips. Compared with traditional methods and circuits, we found that its performance is high and it is flexible for application. By the way, the IP was applied in two FPGA systems successfully and the method is useful for designing other similar circuits. So it is worth to introduce the designing.
