Signal processing apparatus and signal processing method

A signal processing method, comprising the steps of:

• classifying, into a group, a signal communicated between a first processing unit and a second processing unit,
• wherein the second processing unit processes the signal;
• and
• executing a time division multiplexing operation on the signal in the classified group,
• wherein the signal is transmitted, from the first processing unit to the second processing unit, within an updated period and in a range of tolerable delays, and
• wherein the signal is further transmitted, from the first processing unit to the second processing unit, with a minimum number of pins;
• and
• transmitting the signal to the first processing unit.

A non-transitory computer-readable medium having stored thereon computer-executable instructions that, when executed by a computer, cause the computer to execute operations, the operations comprising:

• classifying, into a group, a signal communicated between a first processing unit and a second processing unit,
• wherein the second processing unit processes the signal;
• and
• executing a time division multiplexing operation on the signal in the classified group,
• wherein the signal is transmitted, from the first processing unit to the second processing unit, within an updated period and in a range of tolerable delays, and
• wherein the signal is further transmitted, from the first processing unit to the second processing unit, with a minimum number of pins;
• and
• transmitting the signal to the first processing unit.
