"Nous allons passer en revue les concepts du langage SDL, son historique, et évaluer les forces et faiblesses respectives de SDL et UML afin de projeter ce qui, à notre avis, serait une solution optimale pour l’utilisation de l’un ou l’autre de ces langages."

"This work presents some new optimization approaches to implementation of Medium Access Control (MAC) layer of IEEE 802.11 wireless networking protocol using general purpose DSP and gate array systems. Optimization starts at design level. The hardware/software partitioning of the MAC’s architecture is optimized in the sense of minimal implementation burden, while maintaining the system’s functionalities and performance. The proposed partitioning and implementation technique obviates the use of any Real Time Operating System (RTOS), which leads to a simple, high speed, and low memory structure of the MAC’s software. Also, solutions such as using hash tables and pipeline processing are given and employed to gain a higher speed. The software section is implemented on the popular, low price DSP of TI’s C54 processor, whereas the hardware implementation is realized using Virtex2vp30 from Xilinx."

Eric Brunel is co-founder and CTO of PragmaDev, and co-designer of the SDL-RT language. He also participates in the ITU-T Study Group on System Design Languages. Before the company creation in 2001, he had 10 years of experience as a project leader on development support and modeling tools in a major company in the telecommunication industry. He is a specialist in UML, SDL, and SDL-RT, and is an expert in object oriented development methodologies, extreme programming, and test driven development.
