Apparatus and method for transmitting dynamic data block using annular queue

摘要

The present invention relates to an apparatus and method for transmitting a dynamic data block using an annular queue that sequentially allocates and stores only regions corresponding to the sizes of data blocks transmitted in various sizes, and includes a head pointer and a tail pointer. And an interface buffer means (100) for storing a group of transmitted messages, the register including a register having an offset pointer; Recording buffer means 200 which stores the number N of data of the transmitted message group; Recording table means (300) for storing a memory address for referring to the contents stored in the recording buffer means (200); And generating a tail pointer, which is a read address, by referring to the number of data N and the offset pointer stored in the write buffer means 200, and at the same time, the offset pointer for the next message group. The present invention comprises a pointer updating means (400) for updating the dynamic data blocks in the order of arrival using the annular queue, and stores each message group by specifying an offset pointer which is a reference point indicating the start of the message. By accessing and outputting only the number of data of, there is an effect that can transmit dynamic data without wasting memory.
