Inexpensive commodity microcontrollers are extremely attractive for offloading low-level, real-time computations from high-performance spacecraft computers due to their high functional density and low power, but they have not been widely used because

The inputs of a gate that are logically equivalent (for example, the inputs of a two-input NAND gate) can have different power consumption associated with signal switching at the inputs because of differences in circuit topology. Since the power cons

The current trend in commercial processors of moving to many cores (30 to100 and beyond) on a single die poses both an opportunity and a challenge for space based processing. 1 2 The opportunity is to leverage this trend for space application and thu

This paper presents a fault-tolerant design approach to allow the use of non-hardened commodity microcontrollers as embedded computing nodes in spacecraft, where a high rate of transient errors and occasional latch ups are expected due to the space r

In current processors, the cache controller, which contains the cache directory and other logic such as tag comparators, is active for each instruction fetch and is responsible for 20-25% of the power consumed in the Icache. Reducing the power consum
