This paper presents a flexible timing synchronization scheme alongside the hardware implementation issues on an Altera Stratix-V Field Programmable Gate Array (FPGA) device. The core content of the synchronizer is based on Finite Impulse Response (FIR) filter which operates as a multicorrelator on demand. The term flexibility refers to a specific part of the synchronizer where the multicorrelator reconfigures its FIR filter block on-the-fly by employing Partial Reconfiguration (PR) feature. Moreover, different implementations have been evaluated for the multicorrelator, including MultiplierLess (ML) approach (an approximate computing technique only for autocorrelation purpose) along with the Direct From as well as the Transposed, Parallel, and Pipelined-Parallel Direct Form FIR filters. All the developed architectures are compared to each other in terms of power consumption, silicon area, and maximum frequency. Preliminary synthesis results show that the ML approach achieves better performance (including 94% less power dissipation, 75% less logic utilization as well as 67% fewer registers) than other architectures when performing autocorrelation function. Furthermore, the critical path is analyzed and appropriate optimization techniques (such as DSP register packing and intermediate register insertion) are applied to the best candidates of the architectures mentioned. As the best results, 2.83 speed-up, 56.57% less logic utilization along with 38.86% fewer registers are achieved for different architectures. Accordingly, we discover that the parallel form, as well as the pipelined-parallel one, achieve more interesting results than the transposed version in most of the cases.

Due to the increased popularity of augmented (AR) and virtual (VR) reality experiences, the interest in representing the real world in an immersive fashion has never been higher. Distributing such representations enables users all over the world to freely navigate in never seen before media experiences. Unfortunately, such representations require a large amount of data, not feasible for transmission on today's networks. Thus, efficient compression technologies are in high demand. This paper proposes an approach to compress 3D video data utilizing 2D video coding technology. The proposed solution was developed to address the needs of "tele-immersive" applications, such as VR, AR, or mixed reality with "Six Degrees of Freedom" capabilities. Volumetric video data is projected on 2D image planes and compressed using standard 2D video coding solutions. A key benefit of this approach is its compatibility with readily available 2D video coding infrastructure. Furthermore, objective and subjective evaluation shows significant improvement in coding efficiency over reference technology. The proposed solution was contributed and evaluated in international standardization. Although it is was not selected as the winning proposal, as very similar solution has been selected developed since then. publishedVersion
