Abstract

The invention discloses an implementation method of a processor chip for vector font library operation. The processor chip comprises a central processing unit, a cache region group, a register group,a vector algorithm logic unit, a word stock storage region and a program storage region; wherein the central processing unit is used for controlling the processor chip to work, the cache region groupcomprises a vector font data cache region, a parameter cache region and a vector rendering cache region, and the vector algorithm logic unit is used for forming vector characters. According to the method, a user can use the vector font library under the condition that existing platform MCU hardware configuration is not changed. The development threshold is greatly lowered. The font library displayeffect reaches the vector font library effect on a smart phone and a computer, and cost, development cycle and product quality of a terminal product are optimized.

Description

technical field [0001] The invention relates to the technical field of font chips, in particular to an implementation method of a processor chip used for vector font operations. Background technique [0002] With the rapid development of Internet of Things devices in recent years, the number and types of smart devices have increased significantly, such as smart watches, smart locks, electronic price tags, etc., which have gradually increased information display and Real-time interaction function, so IoT devices have higher and higher requirements for display, and the display screen is gradually shifting from low-resolution black and white screen to high-resolution color screen. Due to the high resolution of the color screen, the requirements for the corresponding font library are also higher. A variety of dot matrix sizes and fonts are required for reasonable typesetting. At the same time, the color screen enables the font library to achieve multi-level grayscale, further op...
