Data Storage Device and Method for On-the-Fly Mathematical Processing of Data Read from the Data Storage Device

A method comprising:

• performing in a data storage device comprising one or more memories:
• receiving, from a host, a data set, a logical address range for the data set, and configuration information;
• creating a mapping between logical addresses in the logical address range and physical addresses in the one or more memories;
• storing the data set in the physical addresses in the one or more memories;
• storing the configuration information in a data structure dedicated to the logical address range;
• receiving, from the host, a read request comprising a set of logical addresses;
• and
• in response to receiving the set of logical addresses in the read request being part of the logical address range:
• using the mapping between logical addresses in the logical address range and physical addresses in the one or more memories to identify neighboring values of a missing value in the data set;
• reading the configuration information from the data structure dedicated to the logical address range wherein the configuration information indicates use of on-the-fly interpolation to generate a replacement for the missing value;
• performing on-the-fly interpolation using the neighboring values to generate the replacement for the missing value;
• and
• sending, to the host, the data set with the interpolated replacement for the missing value.
