Abstract: A circuit arrangement and method of executing program code which utilize power control instructions capable of dynamically controlling power dissipation of multiple hardware resources during execution of a program by a processor. The processor configured to process such power control instructions and to maintain the power modes of the multiple hardware resources to that specified in an earlier-processed power control instruction, such that subsequently-processed instructions will be processed while the power modes of the multiple hardware resources are set to that specified by the earlier-processed power control instruction.

Abstract: A circuit arrangement, method of executing program code and method of generating program code utilize power control instructions (90) capable of dynamically controlling power dissipation of multiple hardware resources (50-60) during execution of a program by a processor (14). Moreover, a processor (14) configured to process such power control instructions (90) is capable of maintaining the power modes of the multiple hardware resources (50-60) to that specified in an earlier-processed power control instruction (90), such that subsequently-processed instructions (90) will be processed while the power modes of the multiple hardware resources (50-60) are set to that specified by the earlier-processed power control instruction (90).

Abstract: The invention is based on the idea to specify operations from different cycles in one instruction and, consequently, to pipeline control connections to remote clusters. Therefore a data processing system is provided. Said system comprises a clustered ILP processor having a plurality of clusters each comprising at least one register file and at least one functional unit, as well as an instruction unit for issuing control signals to the clusters of said processor. The instruction unit is connected to each of said clusters via respective control connections. Furthermore, one or more pipeline register can be arranged in said control connections according to the distance between said instruction unit and the respective clusters.

Abstract: The basic idea of the invention is to provide a clustered ILP processor based on a fully-connected inter-cluster network with a non-uniform latency. A clustered Instruction Level Parallelism processor is provided. Said processor comprises a plurality of clusters (C1-C6) each comprising at least one register file (RF) and at least one functional unit (FUI), wherein said clusters (C1-C6) are fully-connected to each other; and wherein the latency of the connections between said clusters (C1-C6) depends on the distance between said clusters (C1-C6).

Abstract: The basic idea of the invention is to add switches along a bus, in order divide the bus into smaller independent segments by opening/closing said switches. A clustered Instruction Level Parallelism processor comprises a plurality of clusters (C1-C6) each comprising at least one register file (RF) and at least one functional unit (FU), a bus means (100) for connecting said clusters (C1-C6), wherein said bus (100) comprises a plurality of bus segments (100a, 100b, 100c), and switching means (200), which is arranged between adjacent bus segments (100a, 100b, 100c). Said switching means (200) are used for connecting or disconnecting adjacent bus segments (100a, 100b, 100c). Furthermore, a method for accessing a bus (100) in a clustered Instruction Level Parallelism processor is shown. Said bus (100) comprises at least one switching means (200) along said bus (100).
