Abstract
An interface system may include a first interface device and a second interface device. The first interface device may include a first buffer. The second interface device may include a second buffer. The first interface device may compare a write pointer of the first buffer, which corresponds to the second interface device, with a read pointer of the first buffer, which corresponds to the first interface device, and update the read pointer, based on the comparison result. Each of the write pointer of the first buffer and the read pointer of the first buffer may include data bits indicating an address of the first buffer and a data bit indicating a reset signal. The first interface device may selectively update the read pointer according to the reset signal of the write pointer of the first buffer.
Claims20
An interface system comprising:
- a first interface device including a first buffer;
- and
- a second interface device including a second buffer,
- wherein the first interface device compares a write pointer of the first buffer with a read pointer of the first buffer, and updates the read pointer based on the comparison result, the write pointer of the first buffer corresponds to the second interface device, and the read pointer of the first buffer corresponds to the first interface device,
- wherein each of the write pointer of the first buffer and the read pointer of the first buffer includes data bits indicating an address of the first buffer and a data bit indicating a reset signal, and
- wherein the first interface device selectively updates the read pointer according to the reset signal of the write pointer of the first buffer.
A method of operating an interface system including a first interface device including a first buffer and a second interface device including a second buffer, the method comprising:
- comparing, by the first interface device, a write pointer of the first buffer with a read pointer of the first buffer, wherein the write pointer of the first buffer corresponds to the second interface device, and the read pointer of the first buffer corresponds to the first interface device;
- and
- selectively updating, by the first interface device, the read pointer of the first buffer based on the comparison result and a reset signal of the write pointer of the first buffer,
- wherein each of the write pointer of the first buffer and the read pointer of the first buffer includes data bits indicating an address of the first buffer and a data bit indicating the reset signal.
