Abstract

Provided is a method of generating electromagnetic waves using software. The method includes setting electromagnetic wave pattern data in consideration of a number of a bus ( 140, 150 ) connecting a central processing unit (CPU, 110 ) with a main memory ( 130 ) and transmission characteristics of the bus, storing the electromagnetic wave pattern data in a register of the CPU ( 110 ), setting an address in the main memory ( 130 ) at which the electromagnetic wave pattern data will be recorded, and transferring the electromagnetic wave pattern data to the set address in the main memory ( 130 ) through all the lines of the bus ( 140, 150 ). Here, electromagnetic waves corresponding to the electromagnetic wave pattern data are generated while the electromagnetic wave pattern data is transferred to the main memory through the bus.

Claims (22)

1. A method of generating electromagnetic waves using software which is recorded on a computer-readable recording medium, the method executed on one or more processors and comprising:

setting electromagnetic wave pattern data in consideration of a number of lines of a bus connecting a central processing unit (CPU) with a main memory and transmission characteristics of the bus;

storing the electromagnetic wave pattern data in a register of the CPU;

setting an address in the main memory at which the electromagnetic wave pattern data will be recorded; and

transferring the electromagnetic wave pattern data to the set address in the main memory through all the lines of the bus,

wherein electromagnetic waves corresponding to the electromagnetic wave pattern data are generated while the electromagnetic wave pattern data is transferred to the main memory through the bus.

2. The method of claim 1 , further comprising:

periodically changing the electromagnetic wave pattern data to adjust a waveform of the electromagnetic waves.

3. The method of claim 1 , wherein a ratio of “1” bits and “0” bits constituting the electromagnetic wave pattern data is adjusted to control an amplitude of the electromagnetic waves.

4. The method of claim 1 , further comprising:

setting a number of times of transfer of the electromagnetic wave pattern data.

5. A method of generating electromagnetic waves using software which is recorded on a computer-readable recording medium, the method executed on one or more processors and, comprising:

setting electromagnetic wave pattern data in consideration of a number of lines of a bus connecting a central processing unit (CPU) with a main memory and transmission characteristics of the bus;

storing the electromagnetic wave pattern data in the main memory;

setting a register of the CPU in which the electromagnetic wave pattern data will be recorded; and

transferring the electromagnetic wave pattern data to the set CPU register through all the lines of the bus,

wherein electromagnetic waves corresponding to the electromagnetic wave pattern data are generated while the electromagnetic wave pattern data is transferred to the CPU register through the bus.

6. The method of claim 5 , further comprising:

periodically changing the electromagnetic wave pattern data to adjust a waveform of the electromagnetic waves.

7. The method of claim 5 , wherein a ratio of “1” bits and “0” bits constituting the electromagnetic wave pattern data is adjusted to control an amplitude of the electromagnetic waves.

8. The method of claim 5 , further comprising:

setting a number of times of transfer of the electromagnetic wave pattern data.
