摘要： A method in a computer system, one embodiment includes accessing a packed data instruction and generating a corresponding set of control bits to cause a processor to alter a top of stack to zero of a programmer visible register file, accessing a floating point instruction and generating a corresponding set of control bits that cause the processor to operate on the programmer visible register file as a stack, but accessing a transition instruction between the packed data instruction and the scalar floating point instruction and generating a corresponding set of control bits to cause the processor to alter tag data to indicate that programmer visible register file is empty. The method advantageously provides a means for clearing the packed data state at the end of blocks of packed data instructions to leave the floating point state in a clear condition for subsequent operations (e.g. floating point calculations).

摘要： A method in a computer system which includes receiving a first instruction which indicates indicates termination of execution of instructions which operate upon packed data stored in a first storage area. The first storage area is used for modifying data responsive to execution of floating point instructions. A plurality of tags is associated with the first storage area indicating that locations in the first storage area are either empty or non-empty responsive to the execution of the floating point instructions which modify data contained in the first storage area. Responsive to the receiving of the first instruction which indicates termination of execution of instructions which operate upon the packed data stored in the first storage area, the method sets only the plurality of tags to an empty state. In different embodiments, setting of the plurality of tags to a non-empty state occurs responsive to receiving a second instruction. The second instruction (or instructions) specifies an operation upon packed data stored in the first storage area. The setting of the plurality of tags indicates execution of instructions which operate upon the packed data. This method advantageously provides a means for clearing the packed data state at the end of blocks of packed data instructions to leave the floating point state in a clear condition for subsequent operations (e.g. floating point calculations).

摘要： An apparatus (e.g. a microarchitecture of a microprocessor) comprising a plurality of tags associated with a first storage area indicating that locations in the first storage area are either empty or non-empty responsive to execution of floating point instructions which modify data contained in the first storage area. A first circuit is coupled to the plurality of tags which sets only the plurality of tags to an empty state responsive to receipt of a first instruction. The first instruction indicates termination of execution of instructions which operate upon the packed data stored in the first storage area. The apparatus further comprises a second circuit coupled to the plurality of tags for setting the plurality of tags to a non-empty state responsive to receipt of a second instruction (or instructions). The second instruction specifies an operation upon packed data stored in the first storage area. The second circuit further sets the plurality of tags to indicate execution of instructions which operate upon the packed data. This apparatus advantageously provides a architecture (e.g. a microarchitecture for a microprocessor) for clearing the packed data state at the end of executed blocks of packed data instructions to leave the floating point state in a clear condition for subsequent operations (e.g. blocks of executed floating point instructions).

摘要： Methods and apparatuses to clear state for operation of a stack. According to one embodiment of the invention, a processor comprises a set of one or more storage areas and a decode unit. The set of one or more storage areas are to store a plurality of tags and a top of stack indication, where each of the plurality of tags is to indicate if a register is in an empty or non-empty state. The decode unit is to decode scalar floating point instructions and packed data instructions, where at least certain of said scalar floating point instructions specify registers in a stack referenced manner and at least certain of said packed data instructions specify registers in a non-stack referenced manner. In addition, the packed data instructions include an instruction to mark the end of blocks of the packed data instructions in programs. The processor also comprises circuitry to cause the plurality of tags to indicate the empty state responsive to execution of the instruction.

摘要： A method of multiplying and accumulating two sets of values in a computer system. A packed multiply add is performed on a first portion of a first set of values packed into a first source and a first portion of a second set of values packed into a second source to generate a first result. The first result is unpacked into a plurality of values (e.g. two). The plurality of values is then added together to form a resulting accumulation value.

摘要： A method for executing different sets of instructions that cause a processor to perform different data type operations in a manner that is invisible to various operating system techniques, that promotes good programming practices, and that is invisible to existing software conventions. According to one aspect of the invention, a data processing apparatus executes a first set of instructions of a first instruction type on what at least logically appears to software as a single logical register file. While the data processing apparatus is executing the first set of instructions, the single logical register file appears to be operated as a flat register file. In addition, the data processing apparatus executes a first instruction of a second instruction type using the logical register file. However, while the data processing apparatus is executing the first instruction, the logical register file appears to be operated as a stack referenced register file. Furthermore, the data processing apparatus alters all tags in a set of tags corresponding to the single logical register file to a non-empty state sometime between starting the execution of the first set of instructions and completing the execution of the first instruction. The tags identifying whether registers in the single logical register file are empty or non-empty.
