Abstract

Tema tesis ini adalah berdasarkan kepada penggunaan ciri-ciri model selari dalam fasa reka bentuk algoritma untuk mengurangkan kerumitan pengiraan dalam perbandingan dengan algoritma bersiri. Dengan menganggap bahawa seni bina selari membentuk majoriti pengiraan nod dalam peranti digital, cadangan bagi algoritma selari-inheren adalah sesuai. Dalam karya ini, proses atau pengenalan bebenang didaftar dalam satu formula matematik untuk mengurai domain satu, dua, dan domain tiga dimensi. Penyelesaian senario ruang dua dimensi seterusnya disesuaikan sebagai tahap baru keselarian untuk pengekodan piawaian H.264/AVC kerana kerumitan pengiraan yang lebih tinggi daripada pengekodan video ini berbanding dengan piawaian sebelumnya. Tahap baru keselarian untuk pengekod H.264 / AVC ini telah direka untuk mempertimbangkan beberapa metrik pengekodean video dan berorientasikan selari. Kaedah selari peringkat-jubin H.264/AVC yang dicadangkan dibandingkan dengan pendekatan selari tahap kepingan dan tahap blok makro. The theme of this thesis is based on the utilisation of features of the parallel model in the design phase of an algorithm in order to reduce the computational complexity in comparison with the serial algorithm. By assuming that parallel architectures are forming the vast majority of computing nodes in digital devises, proposing inherently-parallel algorithms are no more an overstatement. In this work, the process or thread identification is used in a mathematical formulation to decompose a one-, two, and a three-dimensional domain. Then, the solution of the scenario of two-dimensional space is further customized to serve as a new level of parallelism for the H.264/AVC coding standard due to the higher computational complexity of this video coding in comparison with previous standards. This new level of parallelism for the H.264/AVC encoder has been designed in a way to consider several video coding and parallel- oriented metrics. As a further step, the proposed tile-level parallel H.264/AVC is compared with the slice-level and the macroblock-level parallel approaches.
