Abstract
Provided is a data communication system including a first-in first-out (FIFO) buffer having a fixed size; a central processing unit (CPU) that writes data stored in a memory into the FIFO buffer; a modem that reads the data written by the CPU from the FIFO buffer; and a modem controller that is connected to the FIFO buffer, the CPU, and the modem, respectively, and controls the CPU such that data having a larger volume than the size of the FIFO buffer can be processed.
Claims7
A data communication system comprising:
- a first-in first-out (FIFO) buffer having a fixed size;
- a central processing unit (CPU) that writes data stored in a memory into the FIFO buffer;
- a modem that reads the data written by the CPU from the FIFO buffer;
- and
- a modem controller that is connected to the FIFO buffer, the CPU, and the modem, respectively, and controls the CPU such that data having a larger volume than the size of the FIFO buffer can be processed.
2 more elements
A data communication method comprising:
- writing data into a FIFO buffer having a fixed size, as much as the size of the FIFO buffer;
- reading the data written into the FIFO buffer;
- monitoring the number of data remaining in the FIFO buffer;
- when a predetermined number of data remains in the FIFO buffer, transmitting a control signal to a CPU;
- and
- when the control signal is transmitted, resuming writing data into the FIFO buffer.
