Abstract
In an embodiment of the invention, an apparatus for generating a maximum change data pattern, includes: a shift stage configured to shift a generated signal to the right by one bit and to generate a shifted signal; a logic stage configured to perform an XOR function on the signal and the shifted signal, and generate an XOR output signal; a complement stage configured to complement the XOR output signal, and to generate a complement stage output signal; and a selector configured to select the XOR output signal if the generated signal is even and to select the complement stage output signal if the generated signal is odd.
Claims17
An apparatus for generating a maximum change data pattern, the apparatus comprising:
- a shift stage configured to shift a generated signal to the right by one bit and to generate a shifted signal;
- a logic stage configured to perform an XOR function on the generated signal and the shifted signal, and generate an XOR output signal;
- a complement stage configured to complement the XOR output signal, and to generate a complement stage output signal;
- and
- a selector configured to select the XOR output signal if the generated signal is even and to select the complement stage output signal if the generated signal is odd.
A method for generating a maximum change data pattern, the method comprising:
- shifting a generated signal to the right by one bit, in order to generate a shifted signal;
- performing an XOR function on the generated signal and the shifted signal, in order to generate an XOR output signal;
- complementing the XOR output signal, in order to generate a complement stage output signal;
- and
- selecting the XOR output signal if the generated signal is even, and selecting the complement stage output signal if the generated signal is odd.
An apparatus for generating a maximum change data pattern, the apparatus comprising:
- means for shifting a signal to the right by one bit, in order to generate a shifted signal;
- means for performing an XOR function on the signal and the shifted signal, in order to generate an XOR output signal;
- means for complementing the XOR output signal, in order to generate a complement stage output signal;
- and
- means for selecting the XOR output signal if the generated signal is even, and for selecting the complement stage output signal if the generated signal is odd.
