摘要： Embodiments of the invention provide a programmable FSA building block, having a number of programmable registers and associated logic implemented therein, that provide the capability of contextually evaluating complex REs of arbitrary size against multiple data streams. Embodiments of the invention provide fully programmable hardware in which all of the states of an RE are instantiated and all of the states are fully connected. For one embodiment, the building blocks have a fixed number of states to facilitate implementation on a chip. For such an embodiment, an RE having an excessive number of states is implemented on two or more FSA building blocks and the FSA building blocks are then stitched together to effect evaluation of the RE. For one embodiment, two or more REs having a number of states less than the fixed number of states of a building block may be implemented with a single building block.

摘要： A method for gating a clock signal to an execution unit on long latency memory stalls monitors a stall signal, a scoreboard (data) hazard signal, a resource hazard signal, and a data return signal. The clock signal is decoupled from the execution unit when the stall and data hazard signals are asserted for a selected interval and the data return and resource hazard signals are not asserted for a selected interval.

摘要： A branch prediction instruction is provided that includes hint information for indicating a storage location for associated branch prediction information in a hierarchy of branch prediction storage structures. When the hint information is in a first state, branch prediction information is stored in a first structure that provides single cycle access to the stored information. When the hint information is in a second state, the branch prediction information is stored in a second structure that provides slower access to the stored information.

摘要： An apparatus for storing data in a computer memory, the number originating from one of a plurality of floating point data formats. Each data format from which the number originates has a first exponent bias and a minimum exponent value. The number has a first exponent and an unbiased exponent value, the unbiased exponent value equal to the difference between the first exponent and the first exponent bias. The number also has a sign and a significand. The apparatus for storing the number in computer memory consists of at least one sign bit and a significand having an explicit integer bit, the explicit integer bit having a first predetermined value when the number is normal and having a second predetermined value when the number is denormal. The apparatus also has a second exponent with a second exponent bias, the second exponent equal to the sum of the unbiased exponent value and the second exponent bias when the number is normal, the second exponent equal to the sum of the minimum exponent value and the second exponent bias when the number is denormal.

摘要： Interconnect-dominated large register files are reduced in chip area and delay time. A register file in a processor having a number of execution units is divided into multiple copies. Different groups of execution units can read from and write to their own copy of the file registers by a set of local read and write ports. All of the register-file copies are synchronized by writing data from the execution units to remote write ports in at least some registers in other copies of the register file. Each copy can be divided into local and global registers. While all copies of the global registers continue to be written by the remote write ports, the local registers can be written only by a local cluster of execution units. Alternatively or additionally, all of the execution units can write to their local register-file copy, but only some of the units can write the global registers in all copies of the register file.

摘要： A pipelined data processor has instructions at different stages of execution. Some of the instructions specify virtual addresses into a file of registers having physical addresses. A speculative translator maps the virtual registers of an instruction at one pipeline stage into physical registers for speculative use by the instruction at a later pipeline stage. The registers have multiple differently translated regions. Failure of speculative renaming reverts to an archive copy of renaming data.
