Physical models capture environmental phenomena such as biochemical reactions, a beating heart, or neuron synapses, using mathematical equations. Previous work has shown that physical models can execute orders of magnitude faster on FPGAs (Field-Programmable Gate Arrays) compared to desktop PCs. Different models of the same physical phenomenon may vary, with “upgraded” models being more accurate but...
Cyber-physical systems have become more difficult to test as hardware and software complexity grows. The increased integration between computing devices and physical phenomena demands new techniques for ensuring correct operation of devices across a broad range of operating conditions. Manual test methods, which involve test personnel, require much effort and expense and lengthen a device's time to...
Models of physical systems, such as of human physiology or of chemical reactions, are typically comprised of numerous ordinary differential equations (ODEs). Today's designers commonly consider simulating physical models utilizing field-programmable gate arrays (FPGAs). This letter introduces a resource efficient custom processor—the differential equation processing element, or DEPE—specifically designed...
