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： Disclosed herein is a generational thread scheduler. One embodiment may be used with processor multithreading logic to execute threads of executable instructions, and a shared resource to be allocated fairly among the threads of executable instructions contending for access to the shared resource. Generational thread scheduling logic may allocate the shared resource efficiently and fairly by granting a first requesting thread access to the shared resource allocating a reservation for the shared resource to each other requesting thread of the executing threads and then blocking the first thread from re-requesting the shared resource until every other thread that has been allocated a reservation, has been granted access to the shared resource. Generation tracking state may be cleared when each requesting thread of the generation that was allocated a reservation has had their request satisfied.

摘要： A method of controlling operations by one or more processors includes granting ownership of a memory location having data stored therein to a first processor and performing, in an atomic manner by the first processor, a read operation to load the data from the memory location to a register, a modify operation to modify the data in the register, and a write operation to store the data from the register to the memory location. The method also prevents other operations directed towards the data by a second processor while the read, modify, and write operations are performed by the first processor, and vice versa. Ownership of the memory location is released after performing the read, modify, and write operations so as to allow the first or second processors to perform subsequent atomic operations.
