Topology dependent compensation to improve performance of self-compensated components including processors based on physical relationship with other system components

A multi-processor computer system comprising:

• a bus;
• and
• a plurality of processors coupled to the bus, each having a compensation unit coupled to receive at least two external signals, wherein the compensation unit generates output signals corresponding to operating characteristics for the respective processors, the respective processors further having at least one output buffer coupled to receive the output signals from the compensation unit and operating with the operating characteristics, wherein the operating characteristics are based, at least in part, on a physical relationship with another device.

A method for performance optimization based on topology comprising:

• receiving one or more signals corresponding to a desired slew rate and an impedance for each processor in a multi-processor computer system, wherein the slew rate and the impedance are based, at least in part, on a physical relationship with another device;
• and
• compensating one or more buffers to operate with the desired slew rate and impedance in response to the one or more signals.

An integrated circuit comprising:

• a self-compensated buffer;
• a compensation unit coupled to the self-compensated buffer, the compensation unit configured to receive at least two external signals corresponding to desired operating characteristics, the compensation unit generating output signals to the self-compensated buffer that cause the self-compensated buffer to operate with the desired operating characteristics, wherein the operating characteristics are based, at least in part, on a physical relationship with another device;
• wherein the self-compensated buffer and the compensation unit are part of a processor in a single processor system.
