COUNTER CIRCUIT, DYNAMIC RECONFIGURABLE CIRCUIT, AND LOOP PROCESSING CONTROL METHOD

PROBLEM TO BE SOLVED: To achieve a dynamic reconfigurable circuit including a counter circuit for performing loop processing described in high rank language, and for properly switching context and a loop control processing method. SOLUTION: A dynamic reconfigurable circuit 100 for dynamically switching the processing content and connection content of reconfigurable PE(processing element) 111 according to context, and for performing arbitrary processing is provided with a counter circuit 112 configured of a configuration register part for setting the content of loop processing configured of the output origin of an output signal, the output destination of the output signal, and conditions for outputting the output signal to the output destination from the group of the reconfigured PE based on the context and a loop control part and an output register part for performing the set loop processing, and for counting the number of times of performance of the loop processing performed by the loop control part, and for outputting the output signal to the output destination based on the counted number of times of performance and the conditions.
