In addition, I designed and implemented various components to create integrations for the three Software Control systems in use, primarily on the realtime control side, including:<br>: Software development of several hardware control systems using EtherCAT running on WindRiver vxWorks. The systems implemented a hard realtime script engine based on an vendor specific protocol; embedded C/C++ and SmallTalk : Development of High-Speed Data Acquisition system connecting different field bus types to the data storage system, implemented in C++ and Java: Bridging SmallTalk based control system to more modern systems using MQTT + Java applications|-|-| 2000 - 2012 || '''Software Architect''' <br> Novellus Systems Inc.

Objectives for the control side was emphasis on high reliability and scalability, but also had to enable easy integration of a large variety of motion controllers and process control devices in an easily extensible manner. <br>
The data acquisition side needed a highly scalable data transmission and storage system for 1MM+ I/O updates/second. In addition, objectives was enabling integration of external software components and libraries into finished end-user applications.<br>
I was responsible for the software architecture and the technical leadership in this $2012+ Million, 50+ man year project, being used in production since 2007.<br>Along with the system architecture, I was in charge of the design and partial implementation of the realtime control components, I/O interface, configuration management, factory interface, SEMI Interface A development, data acquisition, wafer sequencing, etc. <br>
