Abstract

A communication apparatus capable of realizing a reduction in power consumption thereof. At least a wireless unit control command analysis/processing section which is operable at a low-speed clock is constituted by a logic circuit. The wireless unit control command analysis/processing section is fed with a low-speed clock as an operation clock therefor. This leads to a reduction in power consumption of the wireless unit control command analysis/processing section.

Claims

1. A communication apparatus comprising:

a data input terminal for receiving a command output from a data terminal unit;

a command analysis processing section for subjecting the command input thereto through said data input terminal to analysis processing, to thereby generate command data;

a control section for receiving the generated command data from the command analysis processing section, and for carrying out required control based on the command data analyzed in said command analysis processing section, to thereby generate transmit data;

an RF transmission section for receiving the transmit data from the control section and for transmitting the transmit data in a form of a predetermined signal;

at least said command analysis processing section being constituted by a logic circuit operated by a first predetermined clock signal, and said control section and RF transmission section operated by respective second and third predetermined clock signals, the first predetermined clock signal being of a lower frequency than the second and third predetermined clock signals.

2. A communication apparatus according to claim 1, wherein the second predetermined clock signal is lower in frequency than the third predetermined clock signal.

3. A communication apparatus according to claim 1, further comprising a buffer RAM connected to the command analysis processing section for storing data input to the command analysis processing section.

4. A communication apparatus according to claim 1, wherein the control section is constituted by a logic circuit.

5. A communication apparatus according to claim 1, wherein the RF transmission circuit is constituted by a logic circuit.

6. A communication apparatus comprising:

first means for receiving a command output from a data terminal unit;

second means for subjecting the command input thereto through said data input terminal to analysis processing, to thereby generate command data;

third means for receiving the generated command data from the second means and for carrying out required control based on the command data analyzed in said command analysis processing section, to thereby generate transmit data;

fourth means for receiving the transmit data from the third means and for transmitting the transmit data in a form of a predetermined signal;

at least said second means being constituted by a logic circuit operated by a first predetermined clock signal, and said third means and fourth means operated by respective second and third predetermined clock signals, the first predetermined clock signal being of a lower frequency than the second and third predetermined clock signals.

7. A communication apparatus according to claim 6, wherein the second predetermined clock signal is lower in frequency than the third predetermined clock signal.

8. A communication apparatus according to claim 6, further comprising fifth means connected to the second means for storing data input to the command analysis processing section.
