Signaloid Ltd. (Cambridge, England), a 2019 startup focused on uncertainty analysis, is offering FPGA development based on a microSD card.

Signaloid’s main business thrust is to provide a computing service to process and track uncertain data dynamically for unmodified computing workloads. This is an alternative to traditional uncertainty analysis and has been offered as a service through the company’s website. Applications of the technology can include materials modeling, autonomous systems, computational finance, machine learning, and noisy intermediate-scale quantum computing.

Probability processing supported on RISC-V core embedded in Lattice FPGA on a microSD card.

However, the Signaloid C0-microSD could provide access to that technology via a Lattice Semiconductor FPGA.

The C0-microSD contains an iCE40UP5K FPGA, 128Mbit of SPI flash and fits in a microSD card socket for programming. This can be used to prototype designs or to add functionality to a larger PCB that contains a microSD slot using the available pins as GPIO.

How good is the data?

The FPGA comes preloaded with the Signaloid C0 RISC-V processor core and a bootloader allowing alternative FPGA bitstreams to be uploaded and RISC-V applications to run via the SD interface. Users are also able to run a subset of Signaloid’s uncertainty-tracking technology.

Signaloid’s approach to computation extends integer and real-valued datatypes to include probability distribution information. This representation persists throughout complex calculations and outperforms other forms of probability analysis, such as Monte Carlo analysis, the company claims. And it does this while running unmodified software.

The company was founded in June 2019 by Professor Phillip Stanley-Marbell who holds the chair of physical computation at the University of Cambridge. Former Arm executive Peter Hutton became a director of the company in July 2021. Hutton is chairman of Agile Analog Ltd. and Cambridge GaN Devices Ltd.

The company announced it had raised £3 million in seed funding led by IQ Capital in May 2023.
