The means for managing the auxiliary processing units include means for allocating an auxiliary logical processing unit to an execution thread to be executed, and means for managing the correspondence between the auxiliary logical processing units and the auxiliary physical processing units. The auxiliary processing units execute in parallel the execution threads for the task by way of the auxiliary logical processing units, which are allocated as late as possible and freed as early as possible. | 12-22-2011 |
20130031309 | SEGMENTED CACHE MEMORY - A cache memory associated with a main memory and a processor capable of executing a dataflow processing task, includes a plurality of disjoint storage segments, each associated with a distinct data category. A first segment is dedicated to input data originating from a dataflow consumed by the processing task. A second segment is dedicated to output data originating from a dataflow produced by the processing task. A third segment is dedicated to global constants, corresponding to data available in a single memory location to multiple instances of the processing task. | 01-31-2013 |
20130247058 | SYSTEM FOR SCHEDULING THE EXECUTION OF TASKS BASED ON LOGICAL TIME VECTORS - A method for scheduling interdependent tasks on a multi-task system includes: associating to each task a logical time vector indicative of the current occurrence of the task and the occurrences of other tasks on which the current occurrence depends; defining a partial order on the set of logical time vectors, such that a first vector is greater than a second vector if all first vector components are greater or equal to the respective second vector components, and at least one component of the first vector is strictly greater than the respective component of the second vector; after an execution of a task, updating its logical time vector for a new occurrence by incrementing at least one component of the vector; comparing the logical time vectors according to the partial order relation; and executing each task having a logical time vector smaller than all other logical time vectors. | 09-19-2013 |
20130263152 | SYSTEM FOR SCHEDULING THE EXECUTION OF TASKS BASED ON LOGICAL TIME VECTORS - A comparator unit for two Nm-bit data words, comprises a comparison output indicative of an order relation between the two data words, the function of the comparison unit being represented by a logic table comprising rows associated with the possible consecutive values of the first data word and columns associated with the possible consecutive values of the second data word, where each row includes a one at the intersection with the column associated with the same value as the row, followed by a series of zeros. The series of zeros is followed by a series of ones completing the row circularly, the number of zeros being the same for each row and smaller than half of the maximum value of the data words. | 10-03-2013 |
