Abstract: As the LCD player is widely used in the embedded system, LCD controller IP becomes an important component of SoC. This paper introduces a design of LCD controller which supports TFT and STN LCD. This design uses a frame rate control algorithm based on space-hash to improve the quality of the LCD display. It uses two-level buffer structure to ensure steady output flow. The paper also introduces a modularized configurable automatic verification scheme. This design has been implemented on FPGA.
