Description
Claims (4)
- 페치된 데이터를 디코드하는 디코드부와, 디코드 결과에 기초하여 연산을 행하는 연산부를 구비한 연산 처리 장치에 있어서,상기 연산부 또는 상기 디코드부의 적어도 한쪽에,제1 입력값의 부호를 반전하는 부호 반전 수단과,제2 입력값의 부호를 판정하는 부호 판정 수단과,상기 부호 판정 수단의 판정 결과가 양인 경우, 상기 제1 입력값을 선택하여 출력하고, 음인 경우, 상기 부호 반전 수단으로부터 입력된 값을 선택하여 출력하며, 0인 경우, 0을 출력하는 출력 선택 수단을 포함하는 것을 특징으로 하는 연산 처리 장치.
- 제1항에 있어서, 상기 제1 입력값과 제2 입력값이 동일한 값이 됨으로써, 상기 출력이 상기 동일한 값의 절대값을 출력하는 것을 특징으로 하는 연산 처리 장치.
- 제1항에 있어서, 상기 제1 입력값과 제2 입력값이 동일한 값이 되고, 이들의 입력값에 대한 상기 출력 선택 수단으로부터의 출력값과 소정의 값을 가산하는 가산 수단과, 또한, 그 가산 결과가 다른 부호 반전 수단의 제1 입력값으로서 입력되고, 또한, 상기 동일한 값이 상기 다른 부호 판정 수단의 제2 입력값으로서 입력됨으로써, 0을 기준으로 하여 상기 동일한 값의 절대값과 상기 소정의 값의 가산 결과만큼 대칭인 값을 출력하는 다른 출력 선택 수단을 또한 구비하는 것을 특징으로 하는 연산 처리 장치.
- 제1항에 있어서, 상기 출력 선택 수단으로부터의 출력값과 상기 제2 입력값을 가산하여, 상기 제2 입력값 또는 상기 제2 입력값을 기준으로 하여 제1 입력값만큼 대칭인 값을 출력하는 가산 수단을 또한 포함하는 것을 특징으로 하는 연산 처리 장치.
