摘要： A condition code register architecture for supporting multiple execution units is disclosed. A master execution unit is coupled a master condition code register such that condition codes generated by the master execution unit are stored in the master condition code register. A non-master execution unit is coupled to a shadow condition code register such that condition codes generated by the non-master execution unit are stored in the shadow condition code register. A tag unit coupled to the master execution unit and the non-master execution unit such that an entry within the master condition code register can be read only when a corresponding entry within the tag unit is referenced to the master execution unit or the master condition code register.

摘要： A processor that promotes accelerated resolution of conditional branch instructions includes an instruction sequencer that fetches a plurality of instructions and a detector that detects, among the plurality of fetched instructions, a condition-setting instruction and a conditional branch instruction that depends upon the condition-setting instruction. The processor further includes a decoder that decodes the conditional branch instruction to produce a decoded condition type and an execution unit. In response to the detection of the condition-setting instruction and the conditional branch instruction, the execution unit resolves the conditional branch instruction by evaluating the condition-setting instruction and the decoded condition type in a single operation. Because the condition code bits are not computed or stored as an intermediate result as in prior art processors, branch resolution is accelerated.
摘要翻译：促进条件分支指令的加速分辨率的处理器包括取指定多个指令的指令定序器和检测器，其在多个取指令中检测条件设置指令和依赖于条件设置的条件转移指令指令。处理器还包括解码器，其解码条件分支指令以产生解码条件类型和执行单元。响应于条件设置指令和条件转移指令的检测，执行单元通过在单个操作中评估条件设置指令和解码条件类型来解析条件转移指令。由于条件码比特不像现有技术的处理器那样计算或存储为中间结果，所以分支分辨率被加速。

摘要： A system for a processor with memory with combined line and word access is presented. A system performs narrow read/write memory accesses and wide read/write memory accesses to the same memory bank using multiplexers and latches to direct data. The system processes 16 byte load/sore requests using a narrow read/write memory access and also processes 128 byte DMA and instruction fetch requests using a wide read/write memory access. During DMA requests, the system writes/reads sixteen DMA operations to memory on one instruction cycle. By doing this, the memory is available to process load/store or instruction fetch requests during fifteen other instruction cycles.

摘要： An apparatus which uses channel counters in combination with channel count read instructions as a means of providing information that data in a given channel is valid or has not been previously read. The counter may also, in the situation of the channel being defined as blocking, be used to prevent the unintentional overwriting of data in a register used by the channel or, alternatively, prevent further communications with the device assigned to that channel when a given count occurs. Intelligent external devices may also use channel count read instructions sent to the counting mechanism for reading from and writing to the channel.

摘要： Disclosed is an apparatus which places computer program instructions into instruction channels in accordance with predefined criteria such that at least some external event instructions are placed in a special “blocking channel.” The number of instructions, in a channel, is monitored in channel specific counters. When a computer processor is awaiting a response from an external entity event (in other words, is blocked from proceeding with the operation the PU is attempting), as signified by the blocking counter being at a predetermined value, the entire PU or at least processor auxiliary components that would be idle, such as math logic, while awaiting an external event response, are deactivated to save power until an awaited external event response is received.

摘要： A bi-endian multiprocessor system having multiple processing elements, each of which includes a processor core, a local memory and a memory flow controller. The memory flow controller transfers data between the local memory and data sources external to the processing element. If the processing element and the data source implement data representations having the same endian-ness, each multi-word line of data is stored in the local memory in the same word order as in the data source. If the processing element and the data source implement data representations having different endian-ness, the words of each multi-word line of data are transposed when data is transferred between local memory and the data source. The processing element may incorporate circuitry to add doublewords, wherein the circuitry can alternately carry bits from a first word to a second word or vice versa, depending upon whether the words in lines of data are transposed.
