Reconfigurable logic circuit using optimal parameter and method of operating the same

A method of operating a reconfigurable logic circuit, the method comprising:

• receiving a video sequence;
• profiling throughput of the video sequence with regard to parameters of the reconfigurable logic circuit including a first parameter and a second parameter to generate a profiling result;
• initializing the first parameter to a first maximum value;
• initializing the second parameter to a second maximum value;
• optimizing the first parameter by searching for a first optimal parameter value maximizing throughput of the video sequence by decreasing a first parameter value of the first parameter based on the profiling result;
• receiving a modified video sequence resulting from a processing of the video sequence based on the first optimal parameter value;
• optimizing the second parameter by searching for a second optimal parameter value maximizing throughput of the modified video sequence by decreasing a second parameter value of the second parameter based on the profiling result;
• and
• analyzing the modified video sequence based on the first optimal parameter value and the second optimal parameter value.

A reconfigurable logic circuit controlled with regard to a parameter, the reconfigurable logic circuit comprising:

• a field programmable gate array (FPGA) block including at least one virtual FPGA (vFPGA);
• a configuration controller configured to profile a video sequence for the parameter and search for an optimal parameter value that maximizes throughput of the FPGA block for the video sequence;
• and
• a task manager configured to map the video sequence to the at least vFPGA to which the optimal parameter value is applied,
• wherein the configuration controller gradually decreases a parameter value of the parameter from a maximum value.
