A method and system for storing instructions retrieved from memory in a memory cache to provide said instructions to a processor. First a new instruction is received from the memory. The system then determines whether the new instruction is a start of a basic block of instructions. If the new instruction is the start of a basic block of instructions, the system determines whether the basic block of instructions is stored in the memory cache responsive. If the basic block of instructions is not stored in the memory cache, the system retrieves the basic block of instructions for the new instruction from the memory. The system then stores the basic block of instructions in a buffer. The system then predicts a next basic block of instructions needed by the processor from the basic block of instructions. The system determines whether the next block of instructions is stored in the cache memory and retrieves the next basic block of instructions from the memory if the next block of instructions is not stored in memory.

The cycle time for a rotomolding process is improved through the use of a molding material comprising a blend of at least two polyethylenes having narrow molecular weight distributions and homogeneous comonomer distributions.

Asynchronous circuitry provides a domino circuit having short cycle times and zero overhead latency. The control circuit of a datapath circuit may utilize a completion signal from the datapath circuit to develop a request signal to the datapath circuit. The request signal may also be based on a request signal from a previous stage. Using the completion signal of a stage to develop the request signal for the same stage allows the circuitry to reduce the impact of constraints that are required for the asynchronous circuitry to operate. Similarly, using the request signal from a previous stage of the asynchronous circuitry to develop the request signal for a present stage also allows the circuitry to reduce the impact of constraints required to implement the asynchronous circuitry. These techniques allow the achievement of fast cycle times while maintaining zero overhead.
