摘要： Methods and apparatus are disclosed for using an index array and finite state machine for scatter/gather operations. Embodiment of apparatus may comprise: decode logic to decode a scatter/gather instruction and generate a set of micro-operations, and an index array to hold a set of indices and a corresponding set of mask elements. A finite state machine facilitates the gather operation. Address generation logic generates an address from an index of the set of indices for at least each of the corresponding mask elements having a first value. An address is accessed to load a corresponding data element if the mask element had the first value. The data element is written at an in-register position in a destination vector register according to a respective in-register position the index. Values of corresponding mask elements are changed from the first value to a second value responsive to completion of their respective loads.

摘要： A processor to perform an out-of-order (OOO) processing in which a reservation station (RS) may generate and process a dependency controlled flow comprising multiple micro-operations (uops) with specific clock based dispatch scheme. The RS may either combine two or more uops into a single RS entry or make a direct connection between two or more RS entries. The RS may allow more than two source values to be associated with a single RS by combining sources from the two or more uops. One or more execution units may be provisioned to perform the function defined by the uops. The execution units may receive more than two sources at a given time point and produce two or more results on different ports.

摘要： Methods and apparatus are disclosed using an index array and finite state machine for scatter/gather operations. Embodiment of apparatus may comprise: decode logic to decode scatter/gather instructions and generate micro-operations. An index array holds a set of indices and a corresponding set of mask elements. A finite state machine facilitates the scatter operation. Address generation logic generates an address from an index of the set of indices for at least each of the corresponding mask elements having a first value. Storage is allocated in a buffer for each of the set of addresses being generated. Data elements corresponding to the set of addresses being generated are copied to the buffer. Addresses from the set are accessed to store data elements if a corresponding mask element has said first value and the mask element is changed to a second value responsive to completion of their respective stores.

摘要： A computer processor, a computer system and a corresponding method involve a reservation station that stores instructions which are not ready for execution. The reservation station includes a storage area that is divided into bundles of entries. Each bundle is switchable between an open state in which instructions can be written into the bundle and a closed state in which instructions cannot be written into the bundle. A controller selects which bundles are open based on occupancy levels of the bundles.

摘要： A device and method may fetch an instruction or micro-operation for execution. An indication may be made as to whether the instruction is dependent upon any source values corresponding to a set of previously fetched instructions. A value may be stored corresponding to each source value from which the first instruction depends. An indication may be made for each of the set of sources of the instruction, whether the source depends on a previously loaded value or source, where indicating may include storing a value corresponding to the indication. The instruction may be executed after the stored values associated with the instruction indicate the dependencies are satisfied.
