356 results about "Micro-operation" patented technology

In computer central processing units, micro-operations (also known as a micro-ops or μops) are detailed low-level instructions used in some designs to implement complex machine instructions (sometimes termed macro-instructions in this context).

Cracking destructively overlapping operands in variable length instructions

A method, information processing system, and computer program product manage computer executable instructions. At least one machine instruction for execution is received. The at least one machine instruction is analyzed. The machine instruction is identified as a predefined instruction for storing a variable length first operand in a memory location. Responsive to this identification and based on fields of the machine instruction, a relative location of a variable length second operand of the instruction with location of the first operand is determined. Responsive to the relative location having the predefined relationship, a first cracking operation is performed. The first cracking operation cracks the instruction into a first set of micro-ops (Uops) to be executed in parallel. The second set of Uops is for storing a first plurality of first blocks in the first operand. Each of said first block to be stored are identical. The first set Uops are executed.

Method and system for multiple branch paths in a microprocessor

A method and system for multiple branch paths in a microprocessor is described. The method includes assigning an identification number (ID) to each of a plurality of micro-operations (uops) to identify a branch path to which the uop belongs, determining whether one or more branches are predicted correctly, determining which of the one or more branch paths are dependent on a mispredicted branch, and determining whether one or more of the plurality of uops belong to a branch path that is dependent on a mispredicted branch based on their assigned IDs.
