Abstract

The present invention relates to method of processing binary program files, the method comprising a step of transferring a binary program file (11) in the form of binary data packets over a communication network (13) between a transmission device (12) of a server platform (10) and a reception device (14) of a target platform (18), a step of reordering the packets suitable for forming reordered-packet groups, and a processing step which is suitable for successively analyzing the reordered-packet groups so as to identify portions of code. The downloading of the binary program file, on the one hand, and the processing of the binary program file, on the other hand, are carried out according to a pipeline principle, which consequently makes it possible to process said binary program files more rapidly.

Claims

1. A method of processing binary program files, comprising a step (21) of transferring a binary program file (11) in the form of binary-data packets (24) over a communication network (13) between a transmission device (12) of a server platform (10) and a reception device (14) of a target platform (18), characterized in that it furthermore comprises:

a step of reordering the packets, which is suitable for forming reordered-packet groups (25),

a processing step, which is suitable for successively analyzing the reordered-packet groups so as to identify portions of code, the steps of transfer, reordering and processing being suitable for being carried out in parallel.

2. A method of processing binary program files as claimed in claim 1, characterized in that the processing step comprises a binary translation substep (22), which is suitable for translating a portion of code compiled for a source platform into a portion of code compiled for the target platform (18).

3. A method of processing binary program files as claimed in claim 2, characterized in that the processing step furthermore comprises a substep (23) of running the portion of code as soon as it has been translated.

7. A “

computer program”

product, in particular for a digital television receiver-decoder, comprising a set of instructions which, when these instructions are loaded into a data-processing circuit of said digital television receiver-decoder, causes said circuit to carry out the method of processing binary program files as claimed in one of claims 1 to 3.

4. A data-processing device (18) which is suitable for receiving binary program files transmitted over a communication network (13) in the form of binary-data packets (24) by a transmission device (12) of a server platform (10), characterized in that said data-processing device comprises:

means for storing data packets,

means for reordering the packets, which are suitable for forming reordered-packet groups,

processing means, which are suitable for successively analyzing the reordered-packet groups so as to identify portions of code, the means for storage, reordering and processing being intended to operate in parallel.

5. A data-processing device (18) as claimed in claim 4, characterized in that the processing means comprise a binary translation unit (15), which is suitable for translating a portion of code compiled for a source platform into a portion of code compiled for the target platform (18).

6. A data-processing device (18) as claimed in claim 5, characterized in that the processing means furthermore comprise a processor (16), which is suitable for running the portion of code as soon as it has been translated.
