摘要： A plurality of processors (10) in a multiprocessor circuit is coupled to a plurality of independently addressable memory banks (12) via a connection circuit (14). The connection circuit is arranged to forward addresses from a combination of the processors (10) to addressing inputs of memory banks (12) selected by the addresses. The connection circuit (14) provides for a conflict resolution scheme wherein at least one of the processors (10) is associated with an associated one of the memory banks (12) as an associated processor. The connection circuit (14) guarantees the associated processor a higher minimum guaranteed access frequency to said associated one of the memory banks (12) than to a further one of the memory banks (12) other than the associated one of the memory banks (12). A defragmenter (16) detects data associated with a task running on the associated processor (10) that is stored on the further one of the memory banks (12) and move said data to the associated one of the memory banks (12) during execution of the task. The defragmenter cause addressing of the data by the associated processor (10) to be remapped from said further one of the memory banks (12) to the associated one of the banks after said moving, preferably incrementally as movement of data progresses.

摘要： Signal stream processing jobs contain tasks (100), each task (100) to be performed by repeated execution of an operation that processes a chunk of data from a stream. Each job comprises a plurality of the tasks (100) in stream communication with one another. A plurality of processing units (10), which are mutually coupled for the communication of signal streams execute that tasks. A preliminary computation is performed for each job individually, to determine execution parameters required for the job to support a required minimum stream throughput rate if each task of the job is executed in a respective context wherein opportunities to start execution of the task occur separated at most by a cycle time T defined for the task. At run time combination of jobs is selected for execution. Groups of the tasks of the selected combination of jobs are assigned to respective ones of the processing units (10), checking that for each particular processing unit (10) a sum of worst case execution times for the tasks assigned to that particular processing unit (10) does not exceed the defined cycle time T defined for any of the tasks (100) assigned to the particular processing unit (10). The processing unit (10) execute the selected combination of jobs concurrently, each processing unit (10) time multiplexing execution of the group of tasks (100) assigned to that processing unit (10).

摘要： The invention relates to a very large instruction word (VLIW) processor, comprising a plurality of execution units (101, 103,105), a register file (109, 111, 113) and a communication network (117) for coupling the execution units and the register file. In case of an application specific VLIW processor, i.e. a VLIW processor designed for handling a specific range of applications, the communication network of the VLIW processor may not support all types of data conversions. Therefore, it may turn out that a certain data type conversion is not possible for some applications to be run on such a VLIW processor. By incorporation a type conversion unit (107) in the architecture of the VLIW processor, it can be guaranteed that any desired data type conversion can be performed. In case of a partially connected communication network (117), a communication device (129) can be incorporated as well in the architecture, allowing every execution unit to transfer a value to the type conversion unit, and allowing the type conversion unit to transfer a value to any segment of the distributed register file.

摘要： A multiprocessing system executes a plurality of processes concurrently. A process execution circuit (10) issues requests to access a shared resource (16) from the processes. A shared access circuit (14) sequences conflicting ones of the requests. A simulating access circuit (12) generates signals to stall at least one of the processes at simulated stall time points selected as a predetermined function of requests from only the at least one of the processes and/or the timing of the requests from only the at least one of the processes, irrespective of whether said stalling is made necessary by sequencing of conflicting ones of the requests. Thus, part from predetermined maximum response times, predetermined average timing can be guaranteed, independent of the combination of processes that is executed.

摘要： A data processor (200) includes an operation execution unit (225) for executing instructions from an instruction memory (210) indicated by a program counter (220). A loop control circuit (230) stores respective associated loop information for a plurality of instruction loops in a register bank (232). The loop information includes at least an indication of an end of the loop and a loop count for indicating a number of times the loop should be executed. The loop control circuit (230) detects that one of the loops needs to be executed and in response to said detection, loads the loop information for the corresponding loop, and controls the program counter to execute the corresponding loop according to the loaded loop information. The loop information is initialized in response to a loop initialization instruction (240), where the initialization instruction is issued prior to and independent of a start of the loop initialized by the loop information.

摘要： A compute program is executed in a VLIW processor, which contains a plurality of functional units and a plurality of register files that are each coupled to a respective subset of the functional units. When a first instruction is executed that results in writing of a result to a register file in a register addressed by a result address from the first instruction, the result is copied to a copy register in a register file. The copy register is selected dependent on the register file to which the result was written, but at least partially independent of the result address, so that results written to different addressed registers in the register file are copied to the same register in the copy file. Subsequently a copy instruction may be executed to copy the result from the copy register file to a second register file, from which the result may be used as operand of another instruction.
