methods. 3. PURPOSE

1. There are alignment problems involved with using the same parameter data-base source code, in both the programmer and the target device. This is a cause for many software maintenance (and development) dilIiculties. In particular, the need to maintain two ver- sions ofthe data-base in parallel disturb to "smoothly" add new parameters to new releases.

2. Necessary conversions due to diierent data repre- sentation, are implemented in code, individually per each paramete,:

3. Putting many parameters at a single block might destroy all parameters next to an address offset error.

  The purpose of the mechanism described in this paper is to provide an improved download process. This method will ease parameters maintenance in both the programmer and the target. It will also contribute to the reliability of download protocol and to the quality of the download software. The software implementing this mechanism may serve as a general download package, usable as a component in future products.

4. COMPONENT'S OF THE MECHANISM

The download mechanism consists of the following
