Abstract
A method of operating a fuel dispenser having a plurality of fuel handling components and a user interface having at least one peripheral device for input of sensitive payment information. One step of the method involves providing control electronics for the fuel dispenser, the control electronics including a multi-core processor having at least two processor cores and an on-board memory located on a common integrated circuit chip. According to another step, pump hydraulic software is executed on a first processor core of the at least two processor cores via a real-time operating system, the pump hydraulic software being in operative communication with at least one of the fuel handling components. Peripheral control software is executed on a second processor core of the at least two processor cores operating via a non-real time operating system separately and asynchronously from the first processor core. The peripheral control software is operative to provide payment instructions via the user interface and receive sensitive payment information via the at least one peripheral device. For example, the pump hydraulic software and the peripheral control software may communicate with each other via the on-board memory of the multi-core processor.
