A processor having a SIMD architecture, including an array of elementary processors, each elementary processor being associated with an elementary memory cell, a central controller connected to the elementary processors by an instruction bus and a status bus. The central controller transmits a sequence of instructions in a loop, each instruction including a calculation flow indicator. Each elementary processor has an instruction filter that makes it possible to reject or take into account an instruction depending on the identifier it contains. This operating mode makes it possible to emulate a MIMD processor on a SIMD architecture.

MIMD processor emulated on SIMD architecture

A method for preloading into a hierarchy of memories, bitstreams representing the configuration information for a reconfigurable processing system including several processing units. The method includes an off-execution step of determining tasks that can be executed on a processing unit subsequently to the execution of a given task. The method also includes, during execution of the given task, computing a priority for each of the tasks that can be executed. The priority depends on information relating to the current execution of the given task. The method also includes, during execution of the given task, sorting the tasks that can be executed in the order of their priorities. The method also includes, during execution of the given task, preloading into the memory, bitstreams representing the information of the configurations for the execution of the tasks that can be executed, while favoring the tasks whose priority is the highest.

The invention relates to a method for scheduling the processing of tasks and to the associated device, the processing of a task comprising a step for configuring resources required for executing the task and a step for executing the task on the thereby configured resources, the method comprising a selection () of at least one level of independent tasks to be processed in accordance with an order of precedence and a step for sorting () out the tasks of the level of tasks to be processed in order to define, an order of priority in the processing of the tasks, depending on the number of resources required for processing the tasks on the one hand and on a time characteristic of the tasks on the other hand.
