We describe the operation of a cryogenic instrumentation platform incorporating commercially- available field-programmable gate arrays (FPGAs). The functionality of the FPGAs at temperatures approaching 4 kelvin enables signal routing, multiplexing, and complex digital signal processing in close proximity to cooled devices or detectors within the cryostat. The performance of the FPGAs in a cryogenic environment is evaluated, including clock speed, error rates, and power consumption. Although constructed for the purpose of controlling and reading out quantum computing devices with low latency, the instrument is generic enough to be of broad use in a range of cryogenic applications.
