Abstract
1. 청구범위 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
외부로부터 데이타를 입력받는 DSP코아의 입력포트를 확장하는 기술이다.It is a technology to expand the input port of DSP core that receives data from outside.
2. 발명이 해결하고자 하는 기술적 과제2. Technical problem to be solved by the invention
데이타 버스의 포트가 수시로 변하기 때문에 래치신호의 특정구간에 있어서만 데이타를 입력시켜야 하므로, 3상태버퍼를 사용할 수 밖에 없어 회로가 불안정하게 동작할 여지가 많아지고, 또한 DSP코아내의 프로그램 입장에 있어서도 외부로부터 읽어들인 후 상태를 판단하여야 하기 때문에 DSP칩의 처리속도가 떨어지는 문제를 해결한다.Since the port of the data bus changes from time to time, the data must be input only in a specific section of the latch signal. Therefore, there is no choice but to use a three-state buffer, which makes the circuit unstable. It solves the problem that the processing speed of DSP chip is slowed down because it needs to judge the state after reading from.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
