Embodiment Construction
[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0041] Such as figure 1 As shown, it is a schematic diagram of the multiprocessor system provided by the first embodiment of the present invention. The multiprocessor system can be a control system in products such as artificial intelligence, multimedia, and voice communication, or a server in a cloud storage system, etc. . The multiprocessor system of this embodiment includes a central processing unit (Central Processing Unit, CPU) 11, a memory 12, a memory mapper 16, and a processor 17, and the central processing unit 11 and the memory 12 are respectively connected to a memory bus. In addition,...

The invention provides a multiprocessor system data processing method and a multiprocessor system. The multiprocessor system comprises a central processing unit, a memory, at least one processor having a different bit width from the memory and at least one memory mapper, wherein each memory mapper is connected with a corresponding processor. The method comprises the steps that each memory mapper converts data of a memory into preset bit width data, and the preset bit width data correspond to the bit width of a processor connected with the memory mapper; the processor reads and processes the preset bit width data generated by the corresponding memory mapper. According to the method and the system disclosed in the invention, the data of the memory is converted into the preset bit width datacorresponding to the bit width of the processor through the memory mapper, so that the processor does not need to have the same bit width as the memory, the flexibility of the multiprocessor system isgreatly improved, the data migration between the processors is avoided, and the cost of the multiprocessor system is saved.
Description
technical field [0001] The present invention relates to the field of computer systems, and more specifically, relates to a multiprocessor system data processing method and a multiprocessor system. Background technique [0002] Multiprocessor Systems (Multiprocessor Systems) refers to two or more processors with similar functions. The processors can exchange data with each other. All processors share memory, I / O devices, controllers and external devices. The entire hardware The system is controlled by a unified operating system, and the overall parallelism of jobs, tasks, programs, arrays and elements at all levels is realized between processors and programs to improve data processing speed. At present, multiprocessors have been widely used in artificial intelligence, multimedia, voice communication and other products. [0003] However, since multiple processors need to share the memory, the multiple processors need to have the same bit width as the memory, which greatly lim...
