Whitepaper on Distributed Ledger Technology

  • ASTRI was commissioned by the Fintech Facilitation Office (FFO) of the Hong Kong Monetary Authority (HKMA) to conduct a research project on Distributed Ledger Technology (DLT). The project led to the “Whitepaper on Distributed Ledger Technology” which documented the R&D findings. DLT, commonly known as Blockchain, is an innovative technology that has significant application benefits. The project’s key objectives have been to carry out an open-minded, in-depth examination of the technology and to identify possible applications of DLT in financial services by engaging in proof-of-concept work. Published in November 2016, the whitepaper aimed to provide the FinTech industry of Hong Kong with a comprehensive introduction to the technology. It also helps the sector in understanding how the technology could be deployed as an innovative solution to enhance and secure business operations while fulfilling regulatory compliance.

    DLT is an innovative technology that offers several benefits such as transparency, resiliency, auditability, and cryptography-enabled security. It is a vibrant technology that has seen prolific R&D work and a widening scope of applications.

    The paper presents a comprehensive study of DLT, especially on its key benefits, risks, and potential applications. It addresses security enforcement and regulatory compliance issues. It also demonstrates how DLT can bring in viable, valuable FinTech applications, with initial findings of three proof-of-concept exercises – mortgage loan application, trade finance, and digital identity management.

    The paper was enriched by valuable contributions from experts in academic banking sectors, as well as by a few groups specialising in DLT. The paper may be downloaded from the HKMA website.

    As DLT continues to evolve, ASTRI will continue its R&D effort in this area and its applications.

    Hardware Accelerated 3D Conversion System

  • Overview

    ASTRI’s hardware accelerated 3D conversion system is equipped with a PCIe FPGA-based hardware accelerator. It can expedite video conversion from 2D to 3D and enhance the resolution to UHD (3840×2160), creating refined 3D images of professional quality. This system is designed for medium to large sized production or conversion studios to accelerate the 3D video conversion or post-production processes and shorten the post-processing time to market. Its user interface is based on a professional video compositing software, Adobe After Effects, with a ASTRI-developed plug-in for the communication with the hardware accelerator.


    Key Features
    • Automatic high accuracy depth map estimation can be achieved in most cases
    • Supports key frame insertion, allows manual intervention for complex scenes, supports a wide range of 3D output formats

    ASIC Implementation

  • ASTRI ASIC Implementation CCG transforms innovative ideas and designs into ICs and products. This involves various design processes covering architecture, digital logic, analog circuitry, physical, component simulation, system testing and software. The Group works closely with other Groups and customers to transform their architecture designs and logic forms into a production-ready silicon and system platform. The support model is flexible enough to balance amongst the various trade-offs based on diversified design scenarios and maximised design value.


    The Group has been developing Analog IP’s for various IC applications. Both Analog IP blocks for SoC application and pure Analog base IC’s are supported. Some of the examples are multi-channel ADC for video application, Network Controller, Motor Driver and Ultra-low power timing control IC.


    Over the years, multiple patents have been filed and granted for several analog circuit designs in the area of low power and area saving. These innovations contributed to the success of ASTRI’s and our customers’ ICs.
