An embedded system expert witness typically has a background and expertise in software engineering, electrical engineering, and/or computer science. Specific expertise in digital signal processing, firmware, embedded system design, FPGAs, wireless communication, or computer architecture may be requested for a litigation support role.
An embedded system is a computer system that is embedded as part of an overall product or device. An embedded system is dedicated to specific tasks, and embedded systems’ complexity varies from a single microcontroller, to systems with multiple units, peripherals and networks. Embedded systems are used in a wide range of devices, a small sampling of which includes card readers, digital cameras, automotive systems, routers, GPS receivers, household appliances, traffic light systems, CNC machines, medical devices, and military devices. With so many diverse applications, the embedded systems industry is growing at an extremely rapid pace. Embedded systems design and development is a very active area, requiring expertise in software design, hardware design and processor architecture.
In embedded system technology litigation, an expert can anticipate expert witness services such as depositions, an expert report, reverse engineering, forensic analysis, and related consulting activities. In high profile cases, or litigation involving a significant financial stake, previous expert witness experience is often a requirement.
