A Carnegie Mellon University spinoff has unveiled an innovative energy-efficient computer chip architecture that holds the potential to revolutionize satellite computing capabilities. Efficient Computer, founded by Brandon Lucia, a professor at Carnegie Mellon University, aims to overcome the limitations of power-constrained computing devices in space with their groundbreaking processor architecture named Fabric.

According to Lucia, the traditional von Neumann model, upon which most modern computers are based, restricts innovation in space due to its high power consumption. To address this issue, Efficient Computer's chip architecture operates in parallel, treating programs as a circuit of instructions that execute as soon as the data is ready. This departure from the sequential approach significantly reduces energy waste.

Lucia expressed that Fabric has immense potential in various markets, including satellites, IoT devices, and edge computers. Enabling more powerful space-based computing is their primary goal, with applications also extending to a wide range of computing use cases.

In a significant development earlier this year, Efficient Computer secured $16 million in seed funding for further technology development. Although the company has not disclosed early customers, it is expected that companies in the space and defense sectors would receive the first Fabric chip designs in 2025.

Preliminary laboratory testing showcased the efficiency of the Fabric architecture as the first prototype chip proved to be 166 times more energy-efficient than the next most efficient ultra-low-power embedded CPU. While the initial chip releases will not be space-qualified, the company plans to deploy them in space within the next few years.

One promising application of Fabric processors is their potential use in Earth observation satellites. These small remote-sensing satellites often collect vast amounts of data but lack the processing power required for on-orbit analysis. The introduction of Fabric chips could enable a higher volume of on-board data processing, even for cubesats, thereby enhancing their analytical capabilities.

If the chip design proves viable, it could revolutionize satellite operations by enabling the implementation of complex artificial intelligence programs for autonomous navigation, data analysis, and anomaly detection. In fact, Carnegie Mellon students are already testing the processor in nanosatellites, further validating its potential.

Lucia acknowledged the challenges of introducing a new chip design in industries that tend to rely on legacy products, particularly in the context of satellites. However, he believes that companies in the Earth observation sector have incentives to take risks with novel technologies that could significantly enhance on-orbit capabilities and extract valuable insights from data.

Efficient Computer also has future plans for a mission in collaboration with Carnegie Mellon University to fly Efficient silicon to low Earth orbit for experiments in satellite constellation autonomy and remote sensor data processing. This test further depicts the company's commitment to advancing satellite computing capabilities.

The development of Efficient Computer's energy-efficient chip architecture represents a significant milestone for the space industry. By overcoming power constraints and enabling more powerful computing, satellites stand to benefit from enhanced capabilities, paving the way for further exploration and insights from the vast data collected in space.
