Patent number: 8032891Abstract: A mobile device (10) manages tasks (18) using a scheduler (20) for scheduling tasks on multiple processors (12). To conserve energy, the set of tasks to be scheduled are divided into two (or more) subsets, which are scheduled according to different procedures. In a specific embodiment, the first subset contains tasks with the highest energy consumption deviation based on the processor that executes the task. This subset is scheduled according to a power-aware procedure for scheduling tasks primarily based on energy consumption criteria. If there is no failure, the second subset is scheduled according to a real-time constrained procedure that schedules tasks primarily based on the deadlines associated with the various tasks in the second subset. If there is a failure in either procedure, one or more tasks with the lowest energy consumption deviation are moved from the first subset to the second subset and the scheduling is repeated.Type: GrantFiled: May 20, 2002Date of Patent: October 4, 2011Assignee: Texas Instruments IncorporatedInventors: Gerard Chauvel, Dominique D'Inverno, Serge Lasserre, Maija Kuusela, Gilbert Cabillic, Jean-Philippe Lesot, Michel Banâtre, Frédéric Parain, Jean-Paul Routeau, Salam Majoul

Patent number: 7565385Abstract: An electronic system comprises a processor, memory coupled to the processor, and an application programming interface that causes an embedded garbage collection object to be active. The memory stores one or more objects that selectively have references from root objects. The embedded garbage collection object preferably uses control data to cause objects to be removed from said memory, the removed objects comprise those objects that were created while an embedded garbage collection object was active and that do not have references from root objects.Type: GrantFiled: April 22, 2004Date of Patent: July 21, 2009Assignee: Texas Instruments IncorporatedInventors: Gerard Chauvel, Serge Lasserre, Dominique D'Inverno, Maija Kuusela, Gilbert Cabillic, Jean-Philippe Lesot, Michel Banâtre, Jean-Paul Routeau, Salam Majoul, Frédéric Parain

Patent number: 7496930Abstract: In some embodiments, a storage medium comprises application software that performs one or more operations and that directly manages a device. The application software comprises instructions that initialize an application data structure (e.g., an object or array) usable by the application software to manage the device and also comprises instructions that map the application data structure to a memory associated with the device without the use of a device driver. In other embodiments, a method comprises initializing an application data structure to manage a hardware device and mapping the application data structure to a memory associated with the hardware device without the use of a device driver. The application data structure may store a single dimensional data structure or a multi-dimensional data structure. In some embodiments, the device being managed by the application software may comprise a display and the application software may comprise Java code.Type: GrantFiled: April 22, 2004Date of Patent: February 24, 2009Assignee: Texas Instruments IncorporatedInventors: Gerard Chauvel, Serge Lasserre, Dominique D'Inverno, Maija Kuusela, Gilbert Cabillic, Jean-Philippe Lesot, Michel Banâtre, Jean-Paul Routeau, Salam Majoul, Frédéric Parain

Patent number: 7434021Abstract: A process and associated system comprise pre-allocating a portion of memory in a first processor based upon a control input and determining in a second processor if the portion of the pre-allocated memory can satisfy a memory allocation request. Further, if a portion of pre-allocated memory can satisfy a memory allocation request, the technique includes assigning the pre-allocated portion of memory to the allocation request. However, if a portion of pre-allocated memory cannot satisfy a memory allocation request, the technique includes allocating a portion of memory in the first processor to the allocation request.Type: GrantFiled: April 22, 2004Date of Patent: October 7, 2008Assignee: Texas Instruments IncorporatedInventors: Gerard Chauvel, Serge Lasserre, Dominique D'Inverno, Maija Kuusela, Gilbert Cabillic, Jean-Philippe Lesot, Michel Banâtre, Jean-Paul Routeau, Salam Majoul, Frédéric Parain

Patent number: 7330937Abstract: A method is disclosed that comprises determining whether a data subsystem is to operate as cache memory or as scratchpad memory in which line fetches from external memory are suppressed and programming a control bit to cause the data subsystem to be operated as either a cache or scratchpad memory depending on the determination. Other embodiments are disclosed herein as well.Type: GrantFiled: April 5, 2004Date of Patent: February 12, 2008Assignee: Texas Instruments IncorporatedInventors: Gerard Chauvel, Serge Lasserre, Dominique D'Inverno, Maija Kuusela, Gilbert Cabillic, Jean-Philippe Lesot, Michel Banâtre, Jean-Paul Routeau, Salam Majoul, Frédéric Parain

Publication number: 20060023517Abstract: Methods, computer-readable media, and systems for dynamic address translation between a source memory space and a target memory space are provided. In some illustrative embodiments, a method is provided for copying data from a source memory space to a target memory space. The method includes extracting a plurality of source data units, each of size s bits, from the source memory space and translating the plurality of source data units into a plurality of target data units. A target data unit is an addressable unit of the target memory space and each target data unit is of size t bits. The method further includes copying the plurality of target data units into a plurality of contiguous transfer units, each of size b bits, in the target memory space.Type: ApplicationFiled: July 21, 2005Publication date: February 2, 2006Applicant: Texas Instruments IncorporatedInventors: Gilbert Cabillic, Salam Majoul

Publication number: 20050033945Abstract: A technique comprises receiving an instruction and dynamically changing the instruction's semantic based on programmable information that is separate from the instruction. The change in semantic may comprise the inclusion of monitoring code that determines a performance characteristic associated with the instruction or a change in the instruction's operation (e.g., the inclusion of read or write barrier operations to support a garbage collector).Type: ApplicationFiled: April 22, 2004Publication date: February 10, 2005Inventors: Gerard Chauvel, Serge Lasserre, Dominique D'Inverno, Maija Kuusela, Gilbert Cabillic, Jean-Philippe Lesot, Michel Banatre, Jean-Paul Routeau, Salam Majoul, Frederic Parain

Publication number: 20040260911Abstract: A preparation method comprises determining whether an instruction contains an unresolved reference and replacing an unresolved instruction with a predetermined instruction containing an operand associated with reference resolution code. A resolution execution method comprises receiving a plurality of instructions, at least one instruction of which comprises a replacement instruction that replaced a previous instruction, determining whether any of the received instructions comprise the replacement instruction, and executing resolution code to resolve a reference upon determining that a received instruction comprises the replacement instruction. The replacement instruction includes an operand that identifies the resolution code. A processor associated with these methods is also disclosed.Type: ApplicationFiled: April 23, 2004Publication date: December 23, 2004Inventors: Gerard Chauvel, Serge Lasserre, Dominique D'Inverno, Maija Kuusela, Gilbert Cabillic, Jean-Philippe Lesot, Michel Banatre, Jean-Paul Routeau, Salam Majoul, Frederic Parain
