【摘要】 图文叠加芯片在生产生活中有着广泛应用,但市场中的动态图文叠加产品通常采用外接微控制器实现图文动态叠加功能。因此,增大了系统的体积,不利于系统设计的小型化。本文介绍将外部微控制器、图文叠加IP核及存储单元集中于一个独立芯片——片上系统的FPGA实现形式,为动态图文显示片上系统的芯片设计提供了功能性验证。更多还原

【Abstract】 A chip for adding information of pictures and characters into video is applied widely in work and lives. Most products of dynamically on-screen display in market work associating with an external microcontroller. As a result, the space occupied by the system is large, which is not suitable for a mini system design. A System-on-Chip based on FPGA is given in the article, which integrates a microcontroller, storages and an IP of on-screen display into a single chip and functionally verifies the chip design of a System-on-Chip for displaying pictures and characters dynamically.更多还原
