Field: Computer technology (Electrical engineering)
Classification: CPC G  Y | IPC G

Claim 12:
13. A storage device comprising:
a solid state drive (SSD) including a nonvolatile memory and a first controller;
a field programmable gate array (FPGA) including a second controller and a processing circuit; and
a global controller coupled to the SSD and the FPGA,
wherein the global controller is configured to select one of a plurality of operation modes for the SSD and the FPGA based on power information,
in a first mode among the plurality of operation modes, the SSD operates with a fixed performance regardless of power consumed by the SSD and the FPGA, and the FPGA operates with a variable performance that depends on the power consumed by the SSD and the FPGA,
in a second mode among the plurality of operation modes, the FPGA operates with the fixed performance regardless of the power consumed by the SSD and the FPGA, and the SSD operates with the variable performance that depends on the power consumed by the SSD and the FPGA, and
the power information includes a target power value that indicates a power limit of the SSD and a power limit of the FPGA.
