An AVS-and object-based coding approach to support scalable coding of plenoptic videos (PVs) is proposed. PVs are simplified dynamic light fields in which the videos are taken at regularly spaced locations along line segments, which can provide a continuum of view point using view synthesis. In previous works, we have explored the object-based coding of PVs using the MPEG-4 object coding framework so as to facilitate its rendering and processing. This paper further studies the objectbased coding of PVs based on the more efficient Audio Video Standard of China (AVS) and incorporate scalability for supporting users with different bandwidths. AVS is China's national standard and it adopts an MPEG-like hybrid compression framework. The proposed AVS-based object coding framework extend AVS by employing temporal and spatialprediction to support multi-view coding for better coding efficiency. Reduced inter-coding dependency is also utilized to facilitate the issue of random access and selective transmission. Moreover, object-based temporal scalability based on a hierarchical-P structure is also illustrated.

“…While AVS-P2 offers less modes when compared with H.264. Further more, for high-resolution ___________________________ This work was supported by 2009CB320903 and NSFC 60802025 applications, AVS-P2 Jizhun Profile shows comparable performance with H.264/AVC for most progressive sequences [1]. So, RDO based mode selection becomes possible for AVS-P2 systems with the reduced number of modes to be considered.…”

Like H.264, AVS video coding standard also uses macroblock (MB) based motion compensation (MC) and mode decision (MD). Rate distortion optimization (RDO) is the best known mode decision method, but with a high computational complexity that limits its applications. In our paper, firstly an MD algorithm based on RDO is given, which makes more mode candidates enter into RDO mode decision with little hardware resource increment. We further analyze the pipeline structure in detail, and implement a block-level 5-stage hardware pipeline. It can support the real time RDO mode decision processing of 1080P@30fps, and the coding efficiency is about 0.5db higher than the traditional SAD method. Our design is described in highlevel Verilog/VHDL hardware description language and implemented under SMIC 0.18-μm CMOS technology with 215K logic gates and 80 KB SRAMs.

“…CMC uses a 2-dimensional sliding window of size 2×2 to compute the interpolation of a single pixel. The coefficients of the interpolation filter are derived from the motion vector for each Macroblock (16×16 block of pixels) [90]. The Chroma component interpolation (Figure 5.1) follows the equation: SEAL is a fast, software-oriented encryption algorithm.…”

To πρόβλημα της αυτόματης δημιουργίας μονάδων υλικό από παραστάσεις υψηλού επιπέδου εφαρμογής είναι στην πρώτη γραμμή της EDA έρευνας κατά τη διάρκεια των τελευταίων ετών. Σε αυτή την διατριβή παρουσιάζουμε μια μεθοδολογία για τη αυτόματη σύνθεση επιταχυντές υλικού από εφαρμογές OpenCL. OpenCL είναι ένα πρόσφατο πρότυπο για τη σύνταξη των προγραμμάτων που εκτελούνται σε πλατφόρμες πολλαπλών πυρήνων και επιταχυντές όπως GPUs. Η μεθοδολογία μας μετατρέπει προγράμματα OpenCL σε επιταχυντές υλικού με βάση αρχιτεκτονικά πρότυπα που ρητά αποσυνδέει τους υπολογισμούς από την μεταφορά δεδομένων από/προς την μνήμη όποτε αυτό είναι δυνατό. Τα πρότυπα μπορούν να συντονιστούν ώστε να παρέχουν ένα ευρύ ρεπερτόριο από επιταχυντές που πληρούν τις απαιτήσεις απόδοσης των χρηστών και τα χαρακτηριστικά της συσκευής FPGA. Επιπλέον ένα σύνολο υψηλής και χαμηλής στάθμης βελτιστοποιήσεις μεταγλωττιστή εφαρμόζεται για να παράγει βελτιστοποιημένα επιταχυντές. Η πειραματική αξιολόγηση δείχνει ότι οι επιταχυντές που δημιουργούνται αποτελεσματικά συντονισμένοι για να ταιριάζει με το μοτίβο πρόσβασης στην μνήμη κάθε εφαρμογής και την υπολογιστική πολυπλοκότητα και να επιτύχουν τις απαιτήσεις απόδοσης των χρηστών. Ένας σημαντικός στόχος του εργαλείου μας είναι η επέκταση της βάσης χρηστών πλατφόρμες FPGA για μηχανικούς λογισμικού ώστε να γίνει ανάπτυξη FPGA συστήματα από μηχανικούς λογισμικού χωρίς την ανάγκη για εμπειρία σχεδιασμού υλικού.
