US 10,372,635 B2 · Dynamically determining memory attributes in processor-based systems

Abstract

Providing dynamic determination of memory attributes in processor-based systems is disclosed. In this regard, in some aspects, a processor-based system comprises a processor device and one or more memory devices, each of which is associated with one of a plurality of memory attributes. The processor device transmits a request to one of the memory devices to determine the memory attribute associated with the memory device. In response to the request, the memory device provides a memory attribute indication that informs the processor device of the memory attribute associated with the memory device. The processor device in some aspects then performs subsequent memory access operations on the memory device based on the memory attribute indication. Some aspects may provide that the processor device also stores the memory attribute indication, and performs subsequent memory access operations based on the stored memory attribute indication.

Dependent claims

A processor-based system for providing dynamic determination of memory attributes, comprising:

a processor device;
and
one or more memory devices each associated with a memory attribute of a plurality of memory attributes;
the processor device configured to:
transmit a request to a memory device of the one or more memory devices to determine a memory attribute of the memory device;
receive, from the memory device, a memory attribute indication indicating the memory attribute of the memory device, wherein the memory attribute comprises an architectural memory type indicating one of a normal memory and a device memory;
and
perform a subsequent memory access operation on the memory device based on the memory attribute indication received from the memory device, wherein the processor device is configured to perform the subsequent memory access operation by being configured to:
determine, based on the memory attribute indication, whether the memory comprises normal memory;
and
responsive to determining that the memory comprises normal memory, enable one or more of a speculative read operation and a cache operation on the memory.
