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

An electronic device, comprising:

• a first circuit module, comprising:
• a write pointer generation circuit, arranged to generate a write pointer;
• and
• a write data generation circuit, arranged to generate a write data;
• and
• a second circuit module, comprising:
• a storage unit, arranged to store the write data;
• a read pointer generation circuit, arranged to generate a read pointer;
• and
• a comparator, arranged to compare the write pointer with the read pointer to determine whether to read the write data from the storage unit to generate a read data;
• wherein the write pointer generated by the write pointer generation circuit and the write data generated by the write data generation circuit are sent to the second circuit module through multiple wires, respectively, and a signal propagation time of the multiple wires is greater than one cycle of a first clock signal used by the first circuit module;
• wherein the storage unit comprises multiple entries, each of the multiple entries comprises multiple flip-flops, and the first circuit module comprises:
• multiple write pulse generation circuits, arranged to generate multiple write pulse signals to the multiple entries, respectively, to selectively write the write data into one of the multiple entries;
• wherein a width of the write data is N bits, each of the multiple entries comprises N flip-flops, a width of the write pointer is M bits, a number of the multiple entries is D, and 2M is greater than D.
