Technologies for discontinuous execution by energy harvesting devices

摘要

Technologies for discontinuous execution include a compiler computing device and one or more target computing devices. The compiler computing device converts a computer program into a sequence of atomic transactions and coalesces the transactions to generate additional sequences of transactions. The compiler computing device generates an executable program including two or more sequences of transactions having different granularity. A target computing device selects an active sequence of transactions from the executable program based on the granularity of the sequence and a confidence level. The confidence level is indicative of available energy produced by an energy harvesting unit of the target computing device. The target computing device increases the confidence level in response to successfully committing transactions from the active sequence of transactions into non-volatile memory. In response to a power failure, the target computing device resets the confidence level and resumes executing the transactions. Other embodiments are described and claimed.

主权项

1. A computing device for compiling code for a target device, the computing device comprising:
a compiler analysis module to (i) convert a computer program into a first sequence of transactions and (ii) coalesce the first sequence of transactions to generate a second sequence of transactions, wherein the second sequence of transactions has a granularity that is more coarse than a granularity of the first sequence of transactions; and a code generation module to generate an executable program for the target device, wherein the executable program includes the first sequence of transactions and the second sequence of transactions, and wherein the executable program selects between the first sequence of transactions and the second sequence of transactions at runtime based on available energy.
