AbstractThe Discrete Cosine Transform (DCT) is the most widely used transform for image compression. An Integer Cosine Transform denoted ICT (10,9,6,2,9,3) has been shown to be a promising alternative to the DCT for its implementation simplicity, close performance and compatibility to the DCT. This paper describes a hardware realization of the 2-D ICT (10,9,6,2,9,3) using two custom designed chips, referred as ICT chip and a Data Sequencer ship. Both chips were implemented on a 3-mu-m gate array with 2800 gates. The chip set can compute 2-D order-8 ICT in less than 19-mu-sec. The speed can be even faster in inverse transform if high sequence coefficients are truncated. An image processing unit based on this chip set has also been developed. Such image processing unit is most useful in image archiving systems such as electronic album.
