Hardware and algorithm study for a fingerprint verification system

Biometrics is the area of knowledge comprising the methods for unique human recognition, based upon one or more intrinsic physical or behavioural traits. The term has its origin in the ancient Greek language (bios ="life" plus metron ="measure"). Among all the biometric techniques[1], some of them of recent development, fingerprinting has been...

A FPGA implementation of a real-time inspection system for steel roll imperfections

Today’s production processes are more and more optimized to be competitive. The production demands are increased for speed and quality. These increased demands do not pass the roll shops in the steel industry. In the roll shop periodically the rolls from the rolling mill are checked for imperfections. The imperfections are detected by special...

A Memory Access and Operator Usage Pro?ler Framework for HLS Optimization: Using the Lucas Optical Flow Algorithm as Case Study

As recon?gurable hardware such as FPGA’s become bigger and bigger, large and complex systems can be implemented in such devices. It becomes a challenge for engineers to manually convert an algorithm in an HDL, considering the pushing time-to-market constraints. High Level Synthesis tools are developed to make this process less laborious. HLS...

Design of a Crypto Core for Securing Intra System-on-Chip Communication

Interconnect centric security in multi core System-on-Chip (SoC) is an area of increasing concern. Monitoring and manipulation of the SoC interconnect yields great potential to bypass higher level security mechanisms. This thesis proposes SoC-TLS: a cryptographic hardware solution aimed to protect intra SoC communication against malicious IP and...

System performance analysis and fixed-point architecture of a gradient-based optical flow algorithm

Optical flow algorithms present a way for computers to estimate motion from the real world. Applications like cloud motion, surveillance and robot eyesight are examples of this. The focus of existing research is mainly on either fast, but poor solutions, or slow but good solutions. In this thesis an approach to improve performance through...
