摘要： A processor including a first execution core section clocked to perform execution operations at a first clock frequency, and a second execution core section clocked to perform execution operations at a second clock frequency which is different than the first clock frequency. The second execution core section runs faster and includes a data cache and critical ALU functions, while the first execution core section includes latency-tolerant functions such as instruction fetch and decode units and non-critical ALU functions. The processor may further include an I/O ring which may be still slower than the first execution core section. Optionally, the first execution core section may include a third execution core section whose clock rate is between that of the first and second execution core sections. Clock multipliers/dividers may be used between the various sections to derive their clocks from a single source, such as the I/O clock.

摘要： A cache memory is constituted with a data array and control logic. The data array includes a number of data lines, and the control logic operates to store a number of trace segments of instructions in the data lines, including trace segments that span multiple data lines. In one embodiment, each trace segment includes one or more trace segment members having one or more instructions, with each trace segment member occupying one data line, and the data lines of a multi-line trace segment being sequentially associated (logically). Retrieval of the trace segment members of a multi-line trace segment is accomplished by first locating the data line storing the first trace segment member of the trace segment, and then successively locating the remaining data lines storing the remaining trace segment members based on the data lines' logical sequential associations.

摘要： According to one aspect of the invention, a microprocessor is provided that includes an execution core, a first replay mechanism and a second replay mechanism. The execution core performs data speculation in executing a first instruction. The first replay mechanism is used to replay the first instruction via a first replay path if an error of a first type is detected which indicates that the data speculation is erroneous. The second replay mechanism is used to replay the first instruction via a second replay path if an error of a second type is detected which indicates that the data speculation is erroneous.

摘要： In a multi-threaded processor, thread priority variables are set up in memory. The actual assignment of thread priority is based on the expiration of a thread precedence counter. To further augment, the effectiveness of the thread precedence counters, starting counters are associated with each thread that serve as a multiplier for the value to be used in the thread precedence counter. The value in the starting counters are manipulated so as to prevent one thread from getting undue priority to the resources of the multi-threaded processor.
