摘要： A computer has a multi-stage execution pipeline and an instruction decoder. The instruction decoder is designed (a) to decode instructions of a complex instruction set for execution by the pipeline, the instruction set being architecturally exposed for execution by user-state programs stored in a main memory of the computer, the instruction set having variable-length instructions and many instructions having multiple side-effects and a potential to raise multiple exceptions, (b) for at least some instructions of the complex instruction set, to issue two or more instructions in a second internal form into the execution pipeline; (c) to generate information descriptive of instructions to be executed by the pipeline, and to store the information into non-pipelined processor registers of the computer; and (d) to determine whether instructions will complete in the pipeline, and to abstain from writing descriptive information into the processor registers for instructions following an instruction determined not to complete. The pipeline exception circuitry is designed to recognize an exception occurring in an instruction after a first side-effect of the instruction has been architecturally committed, and thereupon, to architecturally expose in the processor registers information describing a processor state of the computer, including an intra-instruction program counter value, and to transfer execution to an exception handler. Pipeline resumption circuitry is effective, after completion of the software exception handler, to resume execution of the excepted program based on the information in the processor registers. The processor registers of the computer are designed to architecturally expose sufficient information about the state of the excepted instruction that the transfer and resume are effected without saving processor state to the main memory, the processor registers and general purpose registers of the computer together providing sufficient working storage for execution of the exception handler and resumption of the program, without storing processor state to the main memory.

摘要： A microprocessor chip has instruction pipeline circuitry, and instruction classification circuitry that classifies instructions as they are executed into a small number of classes and records a classification code value. An on-chip table has entries corresponding to a range of addresses of a memory and designed to hold a statistical assessment of a value of consulting an off-chip table in a memory of the computer. Lookup circuitry is designed to fetch an entry from the on-chip table as part of the basic instruction processing cycle of the microprocessor. A mask has a value set at least in part by a timer. The instruction pipeline circuitry is controlled based on the value of the on-chip table entry corresponding to the address of instructions processed, the current value of the mask, the recorded classification code, and the off-chip table.

摘要： A computer. When an instruction calling for an architecturally-visible side-effect in an architecturally-visible storage location is recognized, a value is stored representative of an architecturally-visible representation of the side-effect, a format of the representative value being different than an architecturally-visible representation of the side-effect. Execution is resumed without generating the architecturally-visible side-effect. Later, the architecturally-visible representation corresponding to the representative value is written into the architecturally-visible storage location. On a context switch, a context of a first process is written and a context of a second process is loaded to place the second process into execution. At least some instructions maintain results in storage resources outside the context resource set, and instructions are marked to indicate whether or not a context switch may be performed at a boundary of the marked instruction. Instruction execution is monitored for a condition that is a superset of a condition whose occurrence is desired to be detected, and a first exception is raised as a result of recognizing the superset condition. Software filters the superset condition to determine whether the monitored condition has occurred, and if so, the software establishes a second exception to be raised after execution of further instructions of the instruction stream. When it is recognized that an instruction is to affect the execution of a second instruction, the processor is set into single-step mode. After the second instruction is executed, the computer is set out of single-step mode.

摘要： A method and apparatus for busing data elements within a computing system includes processing that begins by providing, on a shared bus, a first control signal relating to a first transaction during a first bus cycle. The processing continues by providing a second control signal relating to a second transaction and a first address signal relating to the first transaction during a second bus cycle. The processing continues by providing a third control signal relating to a third transaction and a second address signal relating to a second transaction during a third bus cycle. The processing then continues by providing a first status relating to the first transaction and a third addressing signal relating to the third transaction during a fourth bus cycle. The processing then continues by providing a second status relating to the second transaction during a fifth bus cycle. The processing then continues by providing first data relating to the first transaction when the first status is a hit and providing third status relating to the third transaction during a sixth bus cycle.

摘要： A system with a single BIST for an IC that includes a number of memory arrays that may have varying latencies, widths, and depths. A serial bus (which may be a debug bus) connects the BIST controller, each of the memory arrays on the IC, and a controller. Each memory array has an associated Design for Test Assist Logic (DAL) block. The DAL associated with any particular memory array recognizes commands from the BIST that are for the associated memory array, controls the execution of write/read commands for the associated array and sends data read from the memory array along with appropriate commands to the comparator after a latency that is appropriate for the associated array Thus, there are standardized commands from the BIST, but each DAL executes these commands in a manner appropriate for the memory array (or arrays) associated with the particular DAL.

摘要： A pipelined processor executes several stack instructions simultaneously. Additional shadow registers for stack pointers of instructions in the pipeline are not needed. Instead the new stack pointer is generated once at the end of the pipeline and written to the register file. The stack pointer is needed for generating the stack-top address in memory. The stack-top address is generated early in the pipeline. Other stack instructions in the pipeline which have not yet incremented the stack pointer are located with a stack valid bit array. The stack valid array indicates the increment or decrement amounts for stack instructions in each pipeline stage. An overall displacement or increment value is computed as the sum of all increments and decrements for stack instructions in the pipeline which have not yet updated the stack pointer. The overall displacement which accounts for all unfinished stack instructions is added to the stack pointer from the register file to generate the stack-top address. Thus the new stack pointer does not have to be generated before the stack memory is accessed. Pushes or pops are paired by doubling the increment amount in the stack valid bit array and performing a double-width data transfer.

摘要： A method and apparatus for out-of-order memory processing within an in-order processing device includes processing that allows a plurality of memory transactions to be processed in a pipeline manner until a dependency arises between two or more memory transactions. Such processing includes, for each of the plurality of memory transactions, determining whether data associated with the transaction is stored in local cache. If the data is stored in local cache, it is written into a data register in a next pipeline interval. The processing continues by storing the memory transaction in a miss buffer when the data associated with the memory transaction is not stored in the local cache. The processing continues by writing the associated data for the memory transaction identified in the missed buffer into the data register when the data is received without regard to the pipeline manner.
