Implementering av 1D-DCT
Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
IDCT (Inverse Discrete Cosine Transform) is a common algorithm being used with image and sound decompression. The algorithm is a Fourier related transform which can occur in many different types like, one-dimensional, two-dimensional, three-dimensional and many more.
The goal with this thesis is to create a fast and low effect version of two-dimensional IDCT algorithm, where techniques as multiple-constant multiplication and subexpression sharing plus bit-serial and bit-parallel arithmetic are used.
The result is a hardware implementation with power consumption at 19,56 mW.
