Design and Implementation of a Photo Card Reader by a High-integration Chip Solution

In this paper, we propose a design and implementation of photography card reader by utilizing a high integration chip solution. The system uses the two machines: one is a popular card reader and the other is a photo player. To reach a higher level of performance and system flexibility, we integrate many independent components into a single chip and provide a system on chip (SOC) solution. As a result of the high pixel count of the digital still camera (DSC), the system can support up to a 4096x4096 picture. The independent components include memory card access modules, an USB2.0 bridge, a microprocessor (8051), a JPEG decoder, and an image processing unit (IPU), respectively. The JPEG decoder module is designed by pipeline architecture that has the advantage of low latency and high throughput. In the practical measurement for the prototype, our design can provide high performance and a low cost solution for potential consumer electronics.
