Memory access management

A method of memory access management comprising:

• retrieving, at a device, a first memory access instruction from an instruction buffer, the first memory access instruction indicating a first address range of a first memory access operation;
• adding, by the device, an indication of the first memory access instruction to a first scoreboard entry of a plurality of scoreboard entries of a scoreboard;
• and
• based on determining that the first address range at least partially overlaps a second address range associated with a second scoreboard entry of the plurality of scoreboard entries that corresponds to a second memory access instruction, setting an element of a dependency matrix to have a has-dependency value indicating a dependency of the first scoreboard entry on the second scoreboard entry.

A computer-readable storage device storing instructions that, when executed by a processor, cause the processor to:

• retrieve a first memory access instruction from an instruction buffer, the first memory access instruction indicating a first address range of a first memory access operation;
• add an indication of the first memory access instruction to a first scoreboard entry of a plurality of scoreboard entries of a scoreboard;
• and
• based on determining that the first address range at least partially overlaps a second address range associated with a second scoreboard entry of the plurality of scoreboard entries that corresponds to a second memory access instruction, set an element of a dependency matrix to have a has-dependency value indicating a dependency of the first scoreboard entry on the second scoreboard entry.

An apparatus comprising:

• means for retrieving a first memory access instruction from an instruction buffer, the first memory access instruction indicating a first address range of a first memory access operation;
• means for adding an indication of the first memory access instruction to a first scoreboard entry of a plurality of scoreboard entries of a scoreboard;
• and
• means for setting an element of a dependency matrix to have a has-dependency value indicating a dependency of the first scoreboard entry on a second scoreboard entry of the plurality of scoreboard entries, the element set to have the has-dependency value based on determining that the first address range at least partially overlaps a second address range associated with the second scoreboard entry.
