Hardware support of JPEG

Image formats specified by the joint photographic expert group (JPEG) are preferred for images with high colour content. Along with graphic interchange format (GIF) images, JPEG is the most commonly used image format on the Internet and JPEG is the de facto still image format for digital cameras. All major digital camera manufacturers use JPEG as its exclusive or primary still image format. Most JPEG processing occurs in software programs like Microsoft Paint and Adobe Photoshop. Relatively few hardware solutions exist for processing JPEG images. This paper presents a comprehensive literature survey of hardware solutions for JPEG images. Wherever possible, different JPEG formats and accompanying hardware are presented and compared to illustrate various advantages/disadvantages. The performance of hardware and software for JPEG is compared and an overview of commercial hardware for JPEG is also provided
