CORDIC Based Efficient DCT Architecture for low power image computation
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
Co-ordinate rotation digital computer (CORDIC) based digital signal processing has become an important tool in the fields of communications, biomedical and industrial production, providing designers with significant impetus for making algorithm into architecture. With the explosive growth of multimedia services running on portable applications, the demand for low- power implementations of complex signal processing algorithms are tremendously increasing. The most significant part of multimedia systems are the applications involving image and video processing which are very computationally intensive and thus should be implemented with low cost. In order to reduce power consumption, the CORDIC algorithm can be used. Several methods were combined with the CORDIC algorithm but among them DCT (Discrete Cosine Transform) provide a better performance while processing the images. So the low-power design of discrete cosine transform has been of particular interest, since DCT is one of the most computationally intensive operations in video and image compression, and it is widely adopted in many standards such as JPEG, MPEG, and H.264.CORDIC computation along with the DCT architecture can be used to reduce the power consumption in the image computation. By using the Look ahead CORDIC approach the number of iteration and complexity could be reduce. Hence large amount of power savings can be achieved through the specified method.
