The Digital Talking Book (DTB) player is a device for the visually impaired to read, search, navigate and bookmark written material using DAISY and EPUB standards. This paper presents the design and implementation of a DTB player in an FPGA-based embedded system to play audio books containing MP3 (Daisy) files and utilize Text to Speech Synthesis (TTS) for text only books or EPUB books.
A novel embedded OpenRISC platform was developed with Altera FPGA, its source codes were based on OpenRISC1200 intellectual property (IP) core and uClinux. Five algorithms of video special effects for camera applications were proposed and integrated in the drivers, which included mirror effect, line-scanning effect, diff effect, edge blur effect and noise effect. Moreover, a front-end program interface...
