Abstract
이 발명은 중앙 처리 장치의 선택 장치 및 그 방법에 관한 것으로서, 프로세서로부터 제어 대상에 관한 제어 데이터를 입력 받아 제어 대상의 동작을 제어하는 규칙적인 절차로서 신호를 출력하는 하나의 칩으로 되어있는 칩셋과; 제어 대상에 관한 제어 데이터를 출력하며, 상기 칩셋으로부터 제어 데이터를 입력 받고, 그 데이터를 처리하는 중앙 처리 장치와; 상기 중앙 처리 장치의 제어 핀을 칩셋과 연결시켜 동작을 할 수 있게 만들어 주는 스위치 역할을 하는 3상태 버퍼와; 내부에 프로그램 되어 있는 규칙대로 신호를 출력하여서 상기 3상태 버퍼의 스위치 역할을 하는 팔(PROGRAMABLE ARRAY LOGIC, 이하PAL이라함)과; 상기 PAL로 조건을 부여하여서, PAL이 정해진 규칙되로 동작을 하게하는 점퍼 스위치로 이루어지며; 본 발명의 회로를 이용하면 많은 수의 점퍼 스위치 조작이 없이도 3개의 신호를 컨트롤함으로써 8가지의 중앙 처리 장치의 제품을 사용할 수 있으며, 점퍼 스위치가 차지하는 공간이 없게되므로 공가 효율을 높일 수있는 효과를 가진 중앙 처리 장치의 선택 장치 및 그 방법에 관한 것이다.The present invention relates to an apparatus and a method for selecting a central processing unit. ; A central processing unit for outputting control data relating to a control object, receiving control data from the chipset, and processing the data; A tri-state buffer acting as a switch for connecting the control pin of the central processing unit with the chipset to enable operation; An arm that serves as a switch of the three-state buffer by outputting signals according to a rule programmed therein (PROGRAMABLE ARRAY LOGIC, hereinafter referred to as PAL); A jumper switch that imposes a condition on the PAL and causes the PAL to operate according to a predetermined rule; By using the circuit of the present invention, it is possible to use the products of eight central processing units by controlling three signals without a large number of jumper switch operations. The present invention relates to an apparatus for selecting a central processing unit and a method thereof.
