US 2021/0342155 A1 · SYSTEM AND METHOD FOR PREFETCHING INSTRUCTIONS AND DATA

Abstract

Systems and methods for prefetching instructions and data run a program in a test environment, execute a tracing application on the program to collect processor trace data, use the processor trace data to extract a plurality of instruction addresses and a single continuous stack range to be prefetched during a run-time of the program, at initialization of the program, load the extracted plurality of instruction addresses and the extracted stack range, relocate the plurality of extracted instruction addresses and the extracted stack range into the program, and at run-time, prefetch one or more of the plurality of extracted instruction addresses and the extracted stack range during idle time of the program.

Dependent claims

A method for prefetching instructions and data, comprising:

running, by the processor, a program in a test environment;
executing, by the processor, a tracing application on the program to collect processor trace data;
using, by the processor, the processor trace data to extract a plurality of instruction addresses and a single continuous stack range to be prefetched during a run-time of the program;
at initialization of the program, loading by the processor the extracted plurality of instruction addresses and the extracted stack range;
relocating, by the processor, the plurality of extracted instruction addresses and the extracted stack range into the program;
and
at run-time, prefetching by the processor one or more of the plurality of extracted instruction addresses and the extracted stack range during idle time of the program.

4 more elements

A system for prefetching instructions and data, comprising:

a server having a processor, and memory;
and
one or more code sets stored in the memory and executing in the processor, which, when executed, configure the processor to:
run a program in a test environment;
execute a tracing application on the program to collect processor trace data;
use the processor trace data to extract a plurality of instruction addresses and a single continuous stack range to be prefetched during a run-time of the program;
at initialization of the program, load the extracted plurality of instruction addresses and the extracted stack range;
relocate the plurality of extracted instruction addresses and the extracted stack range into the program;
and
at run-time, prefetch one or more of the plurality of extracted instruction addresses and the extracted stack range during idle time of the program.
