Abstract
본 발명은 뉴로모픽 연산 장치에 관한 것이다. 본 발명의 실시예에 따른 뉴로모픽 연산 장치는 펄스폭 변조기, 시냅스 어레이, 발진기, 카운터, 및 보상기를 포함한다. 펄스폭 변조기는 입력 데이터 값에 근거하여 펄스폭 변조 신호를 생성한다. 시냅스 어레이는 펄스폭 변조 신호 및 가중치의 곱셈 연산에 근거하여 시냅스 연산 신호를 생성한다. 발진기는 시냅스 연산 신호의 크기에 의존하는 출력 주파수를 갖는 발진 신호를 생성한다. 카운터는 발진 신호에 포함된 펄스의 개수를 카운팅하여 카운팅 데이터를 생성한다. 보상기는 선형적으로 증가하는 값을 갖는 기준 데이터가 저장된 메모리를 포함한다. 보상기는 기준 데이터와 카운팅 데이터를 비교하여 카운팅 데이터 값을 보상한다. 본 발명에 따른 뉴로모픽 연산 장치는 저전력으로 작은 면적으로 구현되고, 선형성을 확보할 수 있다.
