Electronic device including two circuit modules with long-distance signal transmission

Abstract

An electronic device includes a first circuit module and a second circuit module, wherein the first circuit module includes a write pointer generation circuit and a write data generation circuit for generating a write pointer and a write data; and the second circuit module includes a storage unit, a read pointer generation circuit and a comparator. The storage unit is used for storing the write data, the read pointer generation circuit is used for generating a read pointer, the comparator compares the write pointer and the read pointer to determine whether to read the write data from the storage unit, the write pointer and the write data are sent to the second circuit module through multiple wires, and a signal propagation time of the multiple wires is greater than one cycle of a clock signal used by the first circuit module.
