一种小规模LCD驱动电路IP核的设计

介绍一种全新LCD驱动电路IP核的总体设计。该IP核具有优异的移植性,能使LCD驱动电路的规模可调,而且通过微调就能驱动多数小规模LCD。采用自顶向下的设计方法将其按功能划分为几个主要模块,并分别介绍各个模块的功能。用VHDL语言对LCD驱动电路IP核进行描述,并用FPGA进行系统实现,最后通过仿真验证。

Design of an IP Core for Small Scale LCD Drivers

A new IP core for LCD drivers has been designed. The IP core which exhibits excellently transplantable characteristics can be extensively used in different scale LCDs. The IP core can conveniently modulate the scale of LCD drivers, and a micro- modulation can drive most small scale LCDs. By top- down way the IP core is divided into several modules according to their functions, and these functions are characterized. Meanwhile, the IP core is expressed with VHDL, and systemically realized with FPGA, and finally confirmed by the computer simulation.
