Developing Future High Integrity Processing Solutions

Dave Sanders

Associate Fellow - Complex Electronic Hardware, Rolls-Royce

Rolls-Royce has been developing high integrity digital processing solutions for its safety critical aerospace engine controllers since the 1980s. By the turn of the century, the electronics industry experienced an inflection point. This resulted in a shift to a consumer driven market and a much-reduced focus on the harsh environment electronics and the extended life cycles required by the aerospace industry. As a result, Rolls-Royce took the decision to design its own microprocessor, and for the last 25 years, has been successfully developing harsh environment safety critical processing solutions for all its aerospace engines.

Alongside the ever-increasing performance expectations, the past few years have seen cyber-security become a major driver in new processor developments. This presents new and interesting development challenges that will need to be addressed.

This talk will provide insight into the Rolls-Royce processor strategy and explore the challenges associated with the continued development of future high integrity processing solutions.

About Dave Sanders

Dave Sanders is an Associate Fellow at Rolls-Royce specialising in the development of complex electronic hardware. He has 25 years’ experience working in the electronics industry, with 22 of those developing the safety critical microprocessors that form the heart of the Rolls-Royce control systems for both aerospace and non-aerospace applications. Dave is a member of the European DO254 Users Group since 2012 and has contributed to various regulation working groups including co-authoring AMC 20-152A. He became a Fellow of the IET in 2018 and was awarded the Rolls-Royce Controls Gold Innovation Award in 2015 in recognition of the successful development of the sixth-generation safety critical microprocessor, which has already accumulated over 20 million fault free flying hours. In his spare time, Dave is a keen runner and currently men's captain for Lichfield running club.
