Methods and apparatus to estimate consumed memory bandwidth

A method comprising:

• obtaining a first memory transaction;
• determining a consumed bandwidth associated with the memory transaction;
• permitting transmission of the memory transaction;
• determining whether to gate a second memory transaction generated by a source of the first memory transaction based on the consumed bandwidth of the first memory transaction;
• and
• when it is determined to gate the second memory transaction, preventing transmission of the second memory transaction for an amount of time determined by the consumed bandwidth.

A device comprising:

• transaction source circuitry configured to generate a memory transaction;
• bandwidth estimator circuitry configured to:
• obtain a first memory transaction;
• and
• determine a consumed bandwidth associated with the memory transaction;
• and
• gate circuitry configured to:
• permit transmission of the memory transaction to a memory controller circuitry;
• and
• determine whether to gate a second memory transaction generated by a source of the first memory transaction based on the consumed bandwidth of the first memory transaction;
• when it is determined to gate the second memory transaction, prevent transmission of the second memory transaction for an amount of time determined by the consumed bandwidth;
• and
• the memory controller circuitry configured to:
• process the memory transaction;
• and
• provide results of the memory transaction to the transaction source circuitry.
