    摘要： An apparatus for cooperative sharing of operand access port of a banked register file comprises a partitioned register file, a first group of functional unit, a second group of function units and an access control circuit. The access control circuit includes three control bits to control the accesses to the register file by the functional units for operands. The invention is to relax the constraint encountered by the compiler and a smart assembler using a conventional Ping-Pong file register. The relaxed constraint allows the two banks of the partitioned register file accessed by two instructions simultaneously as long as each corresponding operand of the two instructions are in different register banks. By the relaxed constraint, a compiler and a smart assembler have more choices to schedule instructions in a program, potentially increasing program performance.

    摘要： A pipelined datapath with dynamically reconfigurable pipeline stages is provided, having a pipeline controller which generates clock signals and selects signals based on a system clock and a valid data signal to control each of the registers and each of the multiplexers in the pipeline circuit. In other words, when a valid datum is being processed, the pipeline register is activated to latch the output of the combinational logic circuit; otherwise, when an invalid datum is received, the register is not activated and the datum bypasses the register through a multiplexer. Therefore, the pipeline stages of the pipelined datapath are dynamically reconfigured to save the power dissipation effectively.

    摘要： An inter-cluster communication module using the memory access network is provided, including a plurality of clusters, a memory subsystem, a controller and a switch device. When some clusters issue a load instruction and some clusters issue a store instruction of an identical memory address concurrently, the controller controls the switch device which connects the clusters and the memory banks of the memory subsystem, so that the data item is transmitted from the cluster issuing the store instruction to the cluster issuing the load instruction through the switch device, thereby achieving data exchange between the clusters. Herein, the data item is selectively stored in the memory module depending on the address. Furthermore, the data item is also transmitted between the memory and the clusters over the switch device.
