Information processing device and method

An information processing method executed on an information processing device mounted with an accelerator that executes predetermined processing on data,

• the information processing device including:
• a storage device configured to store data;
• and
• a host control unit configured to request the accelerator to execute the predetermined processing included in a task requested from an outside,
• the information processing method comprising:
• a first step of compressing and storing in the storage device the data;
• and
• a second step of, by the accelerator, reading the data to be processed among the data stored in the storage device and executing the predetermined processing on the data while decompressing the read data in response to a request from the host control unit.

An information processing device comprising:

• a storage device configured to store data;
• an accelerator configured to execute predetermined processing on data;
• and
• a host control unit configured to request the accelerator to execute the predetermined processing included in a task requested from an outside,
• wherein the data is compressed and stored in the storage device,
• wherein the accelerator includes:
• an input/output circuit configured to input and output data from and to the accelerator;
• a decompression circuit configured to decompress the compressed data;
• a processing circuit configured to execute the predetermined processing;
• and
• a memory configured to store data,
• wherein the input/output circuit:
• reads the data to be processed from the storage device and stores the data in the memory in response to a request from the host control unit,
• wherein the decompression circuit:
• decompresses and transfers to the processing circuit the data to be processed stored in the memory,
• wherein the processing circuit:
• executes the predetermined processing on the decompressed data transferred from the decompression circuit, and stores a processing result of the predetermined processing in the memory, and
• wherein the input/output circuit:
• transmits the processing result of the predetermined processing stored in the memory to the host control unit.
