Abstract
A method, system and apparatus to self-determine equalization parameters for a channel. An initiator sends an equalization insensitive signal (EIS) to a responder on channel to be equalized and begins a count. A responder responds with an EIS. When the initiator receives the response EIS the count is terminated. The count, which constitutes a measure of delay in the channel, may be used to determine desirable equalization parameters for the channel.
Claims18
A method comprising:
- self-determining in an initiator equalization parameter for a channel between the initiator and a,responder;
- and
- setting the equalization parameter to have the value.
An apparatus comprising:
- a signal generator to generate an equalization insensitive signal;
- a transmitter to transmit the signal on a first link;
- a receiver to receive a response signal on a second link;
- a counter to maintain a count between a transmission of the signal and a receipt of the response signal;
- and
- logic to set an equalization parameter based on the count.
3 more elements
A system comprising:
- a motherboard;
- a processor to self-determine an equalization parameter for channel or which the processor communicates, the processor coupled to the motherboard;
- a chipset coupled to the motherboard, the motherboard defining a first channel between the chipset and the processor;
- a memory coupled to the motherboard;
- and
- the motherboard defining a second channel between the memory and the chipset.
