Using Hardware Methods to Improve Time-predictable Performance in Real-time Java Systems
Jack Whitham, Neil Audsley and Martin Schoeberl
This paper describes hardware methods, a lightweight and platform-independent scheme for linking real-time Java code to co-processors implemented using a hardware description language (HDL). Intended for use in embedded systems, hardware methods have similar semantics to the native methods used to interface Java code to legacy C/C++ software, but are also time-predictable, facilitating accurate worst-case execution time (WCET) analysis. By reference to several examples, the paper demonstrates the applicability of hardware methods and shows that they can (1) reduce the WCET of embedded real-time Java, and (2) improve the quality of WCET estimates in the presence of infeasible paths.
