Computational Storage NaN Replacement for Low-Latency Data Reads

The data storage device performs value replacement in advance during the read operation itself, before the host needs to process the data. The controller identifies NaN values and replaces them with default values (such as 0) as part of the read process, so that when the host receives the data, the replacement has already been completed. This eliminates the need for the host to perform separate replacement operations afterward, reducing both latency and computational overhead.

The data storage device performs the value replacement operation autonomously during the read process, without requiring the host to implement complex replacement logic. The controller automatically identifies NaN values and performs the replacement using default values defined in the system, effectively making the storage device serve the computational task of value replacement rather than simply storing and retrieving raw data.

The data storage device acts as an intermediary between data storage and data processing. Instead of storing raw NaN values and requiring the host to handle them, the storage device's controller performs the translation and replacement of NaN values with default values during read operations. This intermediary function absorbs the complexity of value replacement, allowing the host to receive cleaned data without needing to implement its own replacement logic.
