摘要： A CAM bank is functionally divided into two or more sub-banks, without replicating CAM driver circuits, by disabling all match line discharge circuits in the bank, and selectively enabling the discharge circuits in entries comprising sub-banks. At least one selectively actuated switching circuit is interposed between the virtual ground node of each discharging comparator in the discharge circuit of a sub-bank and circuit ground. When the switching circuit is in a non-conductive state, the virtual ground node is maintained at a voltage level sufficiently above circuit ground to preclude discharging a connected match line within the CAM access time. When the switching circuit is placed in a conductive state, the virtual ground node is pulled to circuit ground and the connected match line may be discharged by a miscompare. Control signals, which may be decoded from address bits, are distributed to the switching circuits to define the CAM sub-banks.

摘要： Methods and apparatus for voltage scaling are provided. In an example, an operational limit of a processor is determined by varying a supply voltage to force a processor interrupt fault and/or a processor reset. A clock frequency and the supply voltage can be maintained substantially constant for a time duration. If these operational parameters do not force the processor interrupt fault and/or the processor reset, the supply voltage is varied again, and the clock frequency and the supply voltage are maintained substantially constant for a second time duration. The variation continues until initiation of the processor interrupt fault and/or the processor reset, at which time least one of a clock frequency, the supply voltage, and a temperature are recorded as an operational limit. After determining the operational limit, the supply voltage is adjusted to within the operational limit.

摘要： Hazard detection is simplified by converting a conditional instruction, operative to perform an operation if a condition is satisfied, into an emissary instruction operative to evaluate the condition and an unconditional base instruction operative to perform the operation. The emissary instruction is executed, while the base instruction is halted. The emissary instruction evaluates the condition and reports the condition evaluation back to the base instruction. Based on the condition evaluation, the base instruction is either launched into the pipeline for execution, or it is discarded (or a NOP, or null instruction, substituted for it). In either case, the dependencies of following instructions may be resolved.

摘要： Data from a source domain operating at a first data rate is transferred to a FIFO in another domain operating at a different data rate. The FIFO buffers data before transfer to a sink for further processing or storage. A source side counter tracks space available in the FIFO. In disclosed examples, the initial counter value corresponds to FIFO depth. The counter decrements in response to a data ready signal from the source domain, without delay. The counter increments in response to signaling from the sink domain of a read of data off the FIFO. Hence, incrementing is subject to the signaling latency between domains. The source may send one more beat of data when the counter indicates the FIFO is full. The last beat of data is continuously sent from the source until it is indicated that a FIFO position became available; effectively providing one more FIFO position.

摘要： Techniques for ensuring a synchronized predecoding of an instruction string are disclosed. The instruction string contains instructions from a variable length instruction set and embedded data. One technique includes defining a granule to be equal to the smallest length instruction in the instruction set and defining the number of granules that compose the longest length instruction in the instruction set to be MAX. The technique further includes determining the end of an embedded data segment, when a program is compiled or assembled into the instruction string and inserting a padding of length, MAX−1, into the instruction string to the end of the embedded data. Upon predecoding of the padded instruction string, a predecoder maintains synchronization with the instructions in the padded instruction string even if embedded data is coincidentally encoded to resemble an existing instruction in the variable length instruction set.
摘要翻译：公开了用于确保指令串的同步预解码的技术。指令串包含来自可变长度指令集和嵌入数据的指令。一种技术包括定义一个等于指令集中最小长度指令的粒子，并将构成指令集中最长指令的粒子数定义为MAX。该技术还包括当程序被编译或组装成指令串并将长度为MAX-1的填充插入到嵌入数据的结尾的指令串中时，确定嵌入数据段的结束。在预编译填充指令串时，即使嵌入数据被巧合地编码成类似于可变长度指令集中的现有指令，预解码器也保持与填充指令串中的指令的同步。

摘要： A method for optimizing throughput in a microprocessor that is capable of processing multiple threads of instructions simultaneously. Instruction issue logic is provided between the input buffers and the pipeline of the microprocessor. The instruction issue logic speculatively issues instructions from a given thread based on the probability that the required operands will be available when the instruction reaches the stage in the pipeline where they are required. Issue of an instruction is blocked if the current pipeline conditions indicate that there is a significant probability that the instruction will need to stall in a shared resource to wait for operands. Once the probability that the instruction will stall is below a certain threshold, based on current pipeline conditions, the instruction is allowed to issue.
