- Language evaluation for various purposes is an often repeated exercise in industry and academia. Due to the large number of influencing factors the dependence of the result on implicit or explicit assumptions is not always apparent and clear. Based on a systematic evaluation method with a large number of criteria we compare six languages with respect to the suitability as a system specification and description language for telecom applications. The languages under evaluation are VHDL, C++, SDL, Haskell, Erlang, and ProGram, which represent different paradigms. The evaluation method allows to give specific emphasis on particular aspects in a controlled way, which we use to make separate comparisons for pure software systems, pure hardware systems and mixed HW/SW systems.

LIFS: A Tool for Low-Power Implementation of FSMs
- 1999
-
Ingår i: Proceedings of the 17th IEEE Norchip Conference.
-
Konferensbidrag (refereegranskat)abstract
- We present a tool (LIFS) for low-power implementation of finite state machines (FSMs). The tool decomposes a FSM into several small communicating sub state machines (partitions). Low-power operation is achieved since only one partition is active (clocked) at a time, thus fewer registers need to be clocked. The hand-over mechanism between different partitions in the final state machine is controlled by asynchronous controllers. By using an asynchronous hand-over mechanism our approach has up to five times less power overhead than comparable approaches. To show the effectiveness of the LIFS tool, we present experimental results from standard benchmark examples.

Communication in hardware/software embedded Systems : A taxonomy and problem formulation
- 1997
-
Ingår i: Proceedings '97 / 15th NORCHIP Conference : Tallinn, 10 - 11 November 1997 / IEEE Region 8. - Copenhagen : Technoconsult. ; , s. 417-
-
Konferensbidrag (refereegranskat)abstract
- We formulate the problem of communication synthesis in HW/SW embedded systems by (a) investigating the required concepts at the specification level and (b) by analyzing potential communication routes in heterogeneous HW/SW architectures. Thus, we define the input and output for communication synthesis and we formulate a taxonomy for a complete classification of communication in HW/SW embedded systems.

Design of D-AMPS Channel Decoder with Codesign Methodologies
- 1996
-
Ingår i: BEC '96, the 5th Biennial Baltic Electronics Conference, October 7-11, 1996, Tallinn, Estonia : proceedings. - Tallinn, Estonia : Tallinn Technical University. - 9789985590263 ; , s. 491-

Konferensbidrag (refereegranskat)abstract
- This paper is a case study on tool based codesign methodology. The presented methods are observed by applying a D-AMPS channel decoder design to a codesign research tool-kit. The channel decoder functionality is described with five thousand lines of C code. The analysis (profiling, estimation, hardware-software partitioning and verification) of the C description are presented in the paper.
