This tutorial presents an introduction to Altera’s Nios R II processor, which is a soft processor that can be in- stantiated on an Altera FPGA device. It describes the basic architecture of Nios II and its instruction set. The NiosII processor and its associated memory and peripheral components ar ...

Abstract—In this paper, we propose transform-domain algorithms to effectively classify the characteristics of blocks and estimate the strength of the blocky effect. The transform-domain algorithms require much lower computational complexity and much less memory than the spatial ones. Along with the ...
