ABSTRACT:
A transfer data storage system is used in a control processing unit which receives a transfer data in which a plurality of kinds of data having arbitrary data lengths are allocated within each frame, extracts each data within the transfer data included in a predetermined number of frames by the kind of data, and successively stores the extracted data into a memory. The transfer data storage system includes a register having a plurality of stages for holding values corresponding to the number of kinds of data while circulating the values in synchronism with data transfer times when the kind of data of the transfer data being transferred is switched, an adder for adding a value held in a first stage of the register and data length information of each kind of data obtained in a circulating manner, and for inputting an added value to a last stage of the register, and a write counter for loading the value held in the first stage of the register as an initial value at a start of a counting operation and counting a clock signal from the loaded value when the received transfer data corresponds to a start data of the kind of data, and for ending the counting operation when the received transfer data corresponds to an end data of the kind of data.
