Abstract

본 발명은 모듈과 모듈 사이의 데이타 전송시 순서 제어를 능동적으로 하여 시스템 성능을 향상시키고자 한 모듈간의 데이타 전봉방법에 관한 것이다.The present invention relates to a data spreading method between modules in order to improve system performance by actively controlling the order of data transmission between modules.

이러한 본 발명은 전송한 데이타가 발생하면 큐에 저장을 하고 현재 큐에 저장된 데이타의 갯수와 큐 사이즈를 비교하는 제1과정과; 비교결과 큐에 저장된 데이타의 갯수가 큐 사이즈 미만이고 데이타 타입이 실시간 데이타가 아니면 큐 카운트값을 증가시키고 종료하는 제2과정과; 제1과정의 비교결과 큐에 저장된 데이타 갯수가 큐 사이즈 이상이거나 실시간 데이타이면 인터럽트를 수행하고 데이타를 전송하는 제3과정과; 데이타 전송 후 새롭게 큐 사이즈를 결정하고 큐 카운터를 초기화시킨 후 종료하는 제4과정을 순차 실행시키게 되는 것이다.The present invention comprises a first step of storing a transmitted data in a queue and comparing the number of data stored in the current queue with a queue size; If the number of data stored in the queue is less than the queue size and the data type is not real-time data, a second step of increasing and decreasing the queue count value; A third step of performing an interrupt and transmitting data if the number of data stored in the queue is equal to or greater than a queue size or is a real time data; A fourth process of determining a new queue size after data transmission and initializing a queue counter and then terminating the process is sequentially executed.

Claims

A first step of storing the transmitted data in a queue and comparing the number of data stored in the current queue with a queue size; If the number of data stored in the queue is less than the queue size and the data type is not real-time data, a second step of increasing and decreasing the queue count value; A third step of performing an interrupt and transmitting data if the number of data stored in the queue is equal to or greater than a queue size or is a real time data; And a fourth step of determining a new queue size after data transmission and initializing a queue counter.

The method according to claim 1, wherein the queue size determination of the fourth process is determined by the following equation.

(MAX_C) n = MAX_Q * [(R_C) n-1 / MAX_R]

Where MAX_Q is the maximum number of data that can be stored in the system defined queue, MAX_R is the maximum number of interrupt retries defined by the system, n-1 is the previous interrupt, n is the current interrupt, This is the next interrupt.
