Characterizing and Optimizing the Performance of the MAESTRO 49-Core Processor
Abstract
As space-based imagery-intelligence systems become increasingly complex, processing units are needed that can process the extra data these systems seek to collect. However, the space environment presents a number of threats, such as ambient or malicious radiation, that can damage and otherwise interfere with electronic systems. There is a need, then, for processors that can tolerate radiation-induced faults, and that also have sufficient computational power to handle the large ow of data they encounter. This research investigates one potential solution: a multi-core processor that is radiation-hardened and designed to provide highly parallelized MIMD execution of applicable workloads. A variety of benchmarking programs are used to explore the capabilities of this processor. Additionally, the source code is modified in an attempt to enhance the processor speed and efficiency; the consequent improvements in performance are documented.
