Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
표준의 직렬통신에서 사용되는 범용 비동기 송수신기의 수신데이타 처리방법 및 그 장치에 관한 것이다.The present invention relates to a reception data processing method and apparatus thereof for a general-purpose asynchronous transceiver used in standard serial communication.
2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
수신데이타 버퍼에 수신데이타를 적재할때 발생하는 데이타의 유실을 방지하기 위한 것이다.This is to prevent the loss of data that occurs when loading receive data into the receive data buffer.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
본 발명은 소정 크기단위로 수신되는 데이타의 크기가 수신데이타 버퍼에 현재 적재된 데이타의 크기보다 작은 경우에는 수신데이타를 수신데이타 버퍼에 적재하고, 상기 수신데이타의 크기가 수신데이타 버퍼의 적재된 데이타의 크기 이상인 경우에는 적재불가능상태 표시신호를 중앙처리장치로 송출하여 중앙처리장치가 수신데이타에 이미 적재되어 있는 데이타를 읽어들이도록 함으로써 수신데이타 버퍼를 수신데이타를 적재할 수 있는 상태로 만들어 주는 수신데이타 처리방법 및 그 처리장치를 제공한다.According to the present invention, when the size of data received in a predetermined size unit is smaller than the size of data currently loaded in the reception data buffer, the reception data is loaded in the reception data buffer, and the size of the reception data is the data loaded in the reception data buffer. If the size is greater than or equal to, the unloadable status indication signal is sent to the central processing unit so that the central processing unit can read the data already loaded in the receiving data, thereby making the receiving data buffer ready to receive the receiving data. A data processing method and a processing apparatus thereof are provided.
4. 발명의 중요한 용도4. Important uses of the invention
데이타의 유실없이 수신데이타를 효율적으로 처리할 수 있다.Receive data can be processed efficiently without loss of data.
