摘要： A system and method for issuing a processor instruction to multiple processing sections arranged in an out-of-order processing pipeline architecture. The multiple processing sections include a first execution unit with a pipeline length and a second execution unit operating upon data produced by the first execution unit. An instruction issue unit accepts a complex instruction that is cracked into respective micro-ops for the first execution unit and the second execution unit. The instruction issue unit issues the first micro-op to the first execution unit to produce intermediate data. The instruction issue unit then delays for a time period corresponding to the processing pipeline length of the first execution unit. After the delay, a second micro-op is issued to the second execution unit.

摘要： A novel system and method for working around a processing flaw in a processor is disclosed. At least one instruction is fetched from a memory location. The instruction is decoded. A set of opcode compare logic, associated with an instruction decode unit and/or a set of global completion table, is used for an opcode compare operation. The compare operation compares the instruction and a set of values within at least one opcode compare register in response to the decoding. The instruction is marked with a pattern based on the opcode compare operation. The pattern indicates that the instruction is associated with a processing flaw. The pattern is separate and distinct from opcode information within the instruction that is utilized by the set of opcode compare logic during the opcode compare operation.

摘要： A method for creating precise exceptions including checkpointing an exception causing instruction. The checkpointing results in a current checkpointed state. The current checkpointed state is locked. It is determined if any of a plurality of registers require restoration to the current checkpointed state. One or more of the registers are restored to the current checkpointed state in response to the results of the determining indicating that the one or more registers require the restoring. The execution unit is restarted at the exception handler or the next sequential instruction dependent on whether traps are enabled for the exception.

摘要： A system and method for collecting instrumentation data in a processor with a pipelined instruction execution stages arranged in an out-of-order execution architecture. One instruction group in a Global Completion Table is marked as a tagged group. Instrumentation data is stored for processing stages processing instructions associated with the tagged group. Sample signal pulses trigger a determination of whether the tagged group is the next-to-complete instruction group. When the sample pulse occurs at a time when the tagged group is the next-to-complete group, the instrumentation data is written as an output. Instrumentation data present during sample pulses that occur when the tagged group is not the next-to-complete group is optionally discarded. Sample pulses are generated at a rate equal to the desired sample rate times the number of groups in the global completion table to better ensure occurrence of a next-to-complete tagged group.

摘要： A method for converting from binary to decimal. The method includes receiving a binary number, the binary number including one or more sets of bits. An accumulated sum is set to zero. The accumulated sum is in a binary coded decimal (BCD) format. The following loop is repeated for each set of bits in the binary number in order from the set of bits containing the most significant bit of the binary number to the set of bits containing the least significant bit of the binary number: the accumulated sum is converted into a 5,1 code format resulting in an interim sum. The loop also includes repeating for each next bit in the set in order from the most significant bit to the least significant bit in the set: doubling the interim sum; and replacing the least significant bit of the interim sum with the next bit. The last step in the loop includes converting the interim sum into the BCD format and storing the results of the converting in the accumulated sum. Once all of the sets of bits in the binary number have been processed through the loop, the accumulated sum is output as the final result.

摘要： A method for performing decimal division including receiving a scaled divisor and dividend and storing a subset of the multiples of the scaled divisor. An accumulated quotient is initialized to be equal to zero, a first current remainder is initialized to be equal to the scaled dividend, and a second current remainder is initialized to be equal to the scaled dividend minus the scaled divisor. The following loop is performed until a selected number of quotient digits are produced. An estimated next quotient digit is calculated based on the first digit of the first current remainder. A temp remainder is selected to be either the first current remainder or the second current remainder based on the estimated next quotient digit. A first next remainder is calculated by subtracting one of the stored multiples from the temp remainder, where the stored multiple is selected based on a first digit of the first current remainder. A second next remainder is calculated by subtracting an other one of the stored multiples from the temp remainder, where the other one of the stored multiples is selected based on the first current remainder. An actual quotient digits is calculated based on the estimated next quotient digit, the first current remainder and the first next remainder. The accumulated quotient is updated with the actual next quotient digit. Finally, the first current remainder is set to be equal to the first next remainder and the second current remainder is set to be equal to the second next remainder.
