US 2016/0253177 A1 · Universal History Buffer to Support Multiple Register Types

Abstract

An approach is provided in which a mapper control unit receives first dispatch information corresponding to a first instruction that identifies a first register and a first register type. The mapper control unit dynamically configures a first history buffer entry to support the first register type and, in turn, stores content from the first register into the first history buffer entry. The mapper control unit then receives second dispatch information corresponding to a second instruction that identifies a second register and a second register type, which is different than the first register type. The mapper control unit dynamically configures a second history buffer entry to support the second register type and, in turn, stores content from the second register into the second history buffer entry.

Dependent claims

A method implemented by an information handling system that includes a memory and a processor, the method comprising:

receiving first dispatch information corresponding to a first instruction that identifies a first register and a first register type;
dynamically configuring a first history buffer entry to support the first register type and storing first content from the first register into the dynamically configured first history buffer entry;
receiving second dispatch information corresponding to a second instruction that identifies a second register and a second register type;
and
dynamically configuring a second history buffer entry to support the second register type and storing second content from the second register into the dynamically configured second history buffer entry.

2 more elements

An information handling system comprising:

one or more processors;
a memory coupled to at least one of the processors;
and
a set of computer program instructions stored in the memory and executed by at least one of the processors in order to perform actions of:
receiving first dispatch information corresponding to a first instruction that identifies a first register and a first register type;
dynamically configuring a first history buffer entry to support the first register type and storing first content from the first register into the dynamically configured first history buffer entry;
receiving second dispatch information corresponding to a second instruction that identifies a second register and a second register type;
and
dynamically configuring a second history buffer entry to support the second register type and storing second content from the second register into the dynamically configured second history buffer entry.

6 more elements

A computer program product stored in a computer readable storage medium, comprising computer program code that, when executed by an information handling system, causes the information handling system to perform actions comprising:

receiving first dispatch information corresponding to a first instruction that identifies a first register and a first register type;
dynamically configuring a first history buffer entry to support the first register type and storing first content from the first register into the dynamically configured first history buffer entry;
receiving second dispatch information corresponding to a second instruction that identifies a second register and a second register type;
and
dynamically configuring a second history buffer entry to support the second register type and storing second content from the second register into the dynamically configured second history buffer entry.
