| Objectives |
The Microprocessor and Systems Design Group is studying modern microprocessor architectures and organizations. Especially, design concepts for parallel processor architectures (VLIW, superscalar and superpipelined architectures) together with the compilers and code generation techniques needed to effectively exploit the inherent parallelism have been considered in the past. The studies include also alternative computer architectures, java processor designs and microcontrollers for embedded systems. Additionally, the lectures and laboratory courses on microprocessors and microprocessor systems design are regulary given.
Traditionally, the Microprocessor and Systems Design Group is responsible for the hardware developments. During the last two years, the most important developments have been the PCI/SCI bridge and the hardware monitor for the SMiLE PC cluster. Additionally, a microprogrammble processor with AMD's Am2900 series as building blocks has been implemented for the use in the hardware laboratory (TGI).
These hardware developments could only be realized by using modern VHDL-based hardware design tools. This environment comprises tools for schematic entry, boarddesign, simulation, and synthesis. For most of our hardware developments we use programmable logic devices.
Based on this experience, a new research
area will be covered by the group: reconfigurable architectures and their
applications as well as the related topics hardware/software codesign and
rapid prototyping.

Using FPGA as accelerators for microprocessors and rapid prototyping, especially in the Java environment. FPGAs as an Just-In-Time compiler for JAVA can reduce the compilation time dramatically, even with low performance CPUs. As an accompanying effort to the SMiLE-project, own PCI-to-SCI adapters and a sophisticated SCI monitor for performance and communication analysis are being developed. To demonstrate the the internal execution flow of a microprocessor, software and hardware based on the AMD Am2900 is being developed and used for teaching purposes. This project explores the capabilities of DAB for novel data transmission services in cooperation with Bosch and IRT (Institut für Rundfunktechnik). Aiming at hardware/software co-design, an HW/SW- environment for translating Java programs into VHDL and then into Xilinx FPGAs was developed in cooperation with Siemens. This in conventional technique realized computer for education is finished and is used with an appropriate graphic interface in the TGI practical course. Reconfigurable architectures and systems In this field we try to accelerate algorithms and dataflow by implement the architecture in reconfigurable logic. We will also try to exchange the hardware dynamically at runtime like a DLL in Software. |
