Dynamic prioritization of system-on-chip interconnect traffic using information from an operating system and hardware

A method comprising:

• weighting operating system (OS) priority information to generate a first weighted priority value;
• weighting system-on-chip (SoC) hardware priority information to generate a second weighted priority value;
• weighting platform priority information to generate a third weighted priority value;
• summing the first weighted priority value, the second weighted priority value, and the third weighted priority value to generate a quality of service (QoS) value for an SoC interconnect transaction;
• and
• using the QoS value to prioritize the SoC interconnect transaction for arbitration for an SoC interconnect;
• wherein the prioritized SoC interconnect transaction is executed on the SoC.

A system-on-chip (SoC) comprising:

• an interconnect;
• first circuitry to use a first weight value to weight operating system (OS) priority information to generate a first weighted priority value;
• second circuitry to use a second weight value to weight system-on-chip (SoC) hardware priority information to generate a second weighted priority value;
• third circuitry to use a third weight value to weight platform priority information to generate a third weighted priority value;
• fourth circuitry to sum the first weighted priority value, the second weighted priority value, and the third weighted priority value to generate a quality of service (QoS) value for an SoC interconnect transaction;
• and
• an arbiter to use the QoS value to prioritize the first interconnect transaction on the interconnect;
• wherein the prioritized first interconnect transaction is executed on the SoC.
