Apparatuses and methods to change information values
Some embodiments include apparatuses and methods having a component to change a value of a bit among a number of M bits of information when the M bits have the same value and when M exceeds a selected value. At least one of such embodiments can include a transmitting component to provide the information to a connection. At least one of such embodiments can include a receiving component to receive the information from the connection. In at least one of such embodiments, the selected value can include a maximum number of consecutive bits having the same value that such a receiving component can be configured to receive. Other embodiments including additional apparatuses and methods are described.
1. An apparatus comprising:
a first device coupled to a second device, the first device comprising:
a first component including logic configured to scramble data to produce first scrambled data; and
a second component including a transmitter circuit coupled to the logic and configured to transmit the first scrambled data to the second device; and
the second device comprising:
a third component including a receiving circuit coupled to the transmitter circuit and configured to receive the first scrambled data and detect whether the first scrambled data is in error; and
a control component coupled to the logic and the transmitter circuit and configured to request, based on a determination that the first scrambled data is detected in error, the first device to scramble the data to produce second scrambled data and transmit the second scrambled data to the second device, wherein the first device comprises a memory to store the data, and the second scrambled data is produced by the first memory device based on the data stored in the memory of the first device.
2. The apparatus of claim 1 , wherein the first device is configured to store the data in the first device until the first device confirms the first scrambled data is received by the second device and the first scrambled data is not in error.
3. The apparatus of claim 1 , wherein the first component is configured to produce the first scrambled data, such that the first scrambled data includes sequences of bits having different pseudo random values.
4. The apparatus of claim 1 , wherein the first scrambled data includes M consecutive bits having a same value, and the first device comprises a component including additional logic to change a value of at least one bit among the M consecutive bits based on a determination that the M consecutive bits exceeds a limit value L associated with the third component.
5. The apparatus of claim 1 , wherein the first device is configured to send a retransmission notification to the second device after the erroneous scrambled data is transmitted to the second device.
6. An apparatus comprising:
a first device coupled to a second device, the first device comprising:
a first component including logic configured to scramble data to produce first scrambled data;
a second component including additional logic configured to force an error in the first scrambled data and produce erroneous scrambled data;
a third component including a transmitter circuit configured to transmit the erroneous scrambled data to the second device;
the first component to scramble the data to produce second scrambled data; and
the third component to transmit the second scrambled data to the second device after the erroneous scrambled data is transmitted to the second device, wherein the second component is to force the error in the first scrambled data based on a determination that M bits of the first scrambled data have a same value and M exceeds a selected value L.
7. The apparatus of claim 6 , wherein the second component is not to force the error in the first scrambled data based on a determination that M does not exceed the selected value L.
8. The apparatus of claim 6 , wherein the second device is configured to send a retransmission request to the first device after the second device receives the erroneous scrambled data.
9. The apparatus of claim 6 , wherein the second device is configured to send a retransmission request to the first device after the second device receives the erroneous scrambled data.
