US 12,645,459 B2 · Reduction of data transfer overhead

Abstract

Aspects of the disclosure are directed to reduction of data transfer overhead. In accordance with one aspect, increment a function call counter for an executed function call; decrement the function call counter for an executed return from function call; infer the indirect branch address based on a function call counter value and when a cumulative count of received executed atoms indicates a return from function call has been executed; oversaturate the function call counter at a maximum counter value if the function call counter contains the maximum counter value and a subsequent function call is executed; and undersaturate the function call counter at a minimum counter value if the function call counter contains the minimum counter value and a subsequent return from function call is executed.

Dependent claims

An apparatus comprising:

a tracing hardware configured to:
a) provide a record of a plurality of executed instructions, wherein one of the plurality of executed instructions includes an indirect branch address, and
b) generate a plurality of packets based on the plurality of executed instructions;
and
a decoder coupled to the tracing hardware, wherein the decoder includes a first counter configured to increment or to decrement a counter value based on the plurality of executed instructions, and the decoder is configured to:
a) receive the plurality of packets,
b) infer the indirect branch address associated with a return from function call based on a memory structure and a fixed word size as an address offset corresponding to a previous function call, and
c) to recover the plurality of executed instructions.
