Annual Report 2002 - Örebro universitet

54 AASS – Center for Applied Autonomous Sensor Systems
Project title: Fast Hardware for Fuzzy Logic Signal and Image Processing
Project leader: Docent Ivan Kalaykov
Project staff: Gustav Tolt
Project funding: KK Foundation and Faculty
Cooperation: Hardi Electronics AB, Lund (started end of 2002)
Synopsis
The project has several objectives the common denominator of which is achieving high-speed
image processing. The first objective is to build a high-speed fuzzy logic processor able to
operate at speeds more than 50 MFLIPS (Mega Fuzzy Logic Inferences Per Second) . Here
major contributions are: new concept of Fired-Rules-Hyper-Cube (FRHC) concept created as
a base for the hardware design; layered parallel and pipelined architecture with predictable
behavior in time; high-speed performance that can be optimized depending on the progress of
the semiconductor technology. The second objective is to design and develop high-speed
vision system in hardware able to provide over 50-60 frames per second for typical image
processing algorithms. It is needed for real-time control of high-speed motion. Major
contributions are: high-speed vision sensor for robot motion control; embedded high-speed
image processing algorithms using fuzzy logic; programmable architecture
Results in 2002:
- One WIPO international patent is already obtained.
- Basic structures for image processing are developed and simulated.
Future developments:
- Implementing the main results achieved so far on advanced FPGA-based boards and
completing IP-cores for FPGA-based design of complex processing systems. Working
prototype system and experimental tests will be done in 2003. Part of this work is to be
included in the PhD thesis of Gustav Tolt.
