- We have separated the information required for HW /SW interface synthesis into three parts, the protocol specification, the operating system related information, and the processor related information. From these inputs a synthesis tool generates (a) device driver functions or (b) a combination of device driver functions and a DMA controller, depending on a designer’s decision. The clean separation of information facilitates (1) efficient design space exploration with combinations of different processors, operating systems and protocols, and (2) maintaining a large number of different versions and variants of HW /SW interfaces by synthesising them on demand. Protocols are specified as a grammar, which is fully independent of architecture and implementation. From this the synthesis tool generates device driver code in C and /or synthesizable RTL code in VHDL for DMA controllers. After the initial selection of implementation alternatives the presented methods are fully automated. Its computational complexity is quadratic in terms of the number of states. With real-life examples we show that the quality of the generated code is close to hand written quality in terms of performance, area and code size.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Shortened design and life time of embedded systems has motivated active research in HW/SW co-design area, together with evolution of relatively long-life of reconfigurable HW. In this paper we present Akka1[1][2] - a set of tools for design space exploration, co-simulation and co-synthesis with two industrial examples from the telecommunication field - Maintenance functionality of the ATM protocol and Channel decoder functionality of a D-AMPS base station. For fast prototyping we have selected Xilinx XC4013 FPGA based board from Virtual Computer Corporation. The board is connected to the system bus (SBus) of the host computer.

Tidskriftsartikel (refereegranskat)abstract
- Grammars define syntax of languages and as such have not been commonly considered as methods for design, despite well-known applications in computer science. Only in recent years grammar-based design has become a promising research field and the first commercial tools have appeared on the market. This paper reviews the basic concepts of applying grammars to electronic design - in particular to the device driver synthesis of communication protocols for embedded software, to the design of custom-hardware, and to the virtual prototyping of DSP systems. The paper shows the power of these methods, presents the latest research results and discusses future developments in this field.
