Embodiment 1

[0064] Figure 1A , Figure 1B Schematic configurations of the processing unit and the control unit in Embodiment 1 of the present invention are shown respectively.

[0065] Figure 1A Among them, the processing unit 100 has a processing unit 101 , a data storage unit 102 and a communication unit 103 . The so-called "processing unit" refers to a constituent unit of the system that realizes at least one of the four functions of data input and output, processing, transmission, and storage.

[0066] The processing unit 101 executes a specific function. The communication unit 103 outputs function information related to a specific function to the outside in response to a request from the outside. Furthermore, the data holding unit 102 holds function information.

[0067] Here, the processing unit 101 may have a function of merely passing data, that is, merely transmitting without processing. In addition, the data holding unit 102 may have a rewritable configuration, for example...

Embodiment 2

[0157] Next, the distributed processing method according to Embodiment 2 of the present invention will be described. Figure 19 , Figure 20 , Figure 21 It is a flowchart showing the flow of the distributed processing method according to this embodiment.

[0158] In step S1900, the control unit CU1 initializes the above-mentioned processing component connection table. At this time, the control unit CU1 also obtains the information of the processing unit connection table of the control units on the predetermined hierarchy (for example, the number of hierarchies=1). The concept of hierarchy will be described later. In addition, the control unit CU1 initializes the task execution transition table.

[0159] The so-called level refers to the communication distance from the control unit to other control units. Communication distance can be defined by any metric, but most commonly expressed by the time it takes for information to arrive (response speed). In addition to the cla...

Abstract

A processing system is comprised of a processing element (100) and a control unit (200). The processing element (100) is provided with a processing unit (101) for performing a specific function, a communication unit (103) for outputting functional information about the specific function in response to an external request to the outside, and a data holding unit (102) for holding the functional information. The control unit (200) is provided with a communication unit (202) for outputting the functional information of the processing element (100) linked in response to the external request.

Description

technical field [0001] The present invention relates to a processing unit, a control unit, a processing system including these, and a distributed processing method. Background technique [0002] Conventionally, when performing processing consisting of a plurality of steps, the following three methods (1), (2), and (3) are considered to be used. [0003] (1) A method for solving all steps through software; [0004] (2) A method of replacing a part of steps (functions) with hardware; [0005] (3) A method of solving all steps by hardware. [0006] In the method (1), for example, all steps are described in software on a general-purpose CPU. When each step is realized as a subroutine or a thread by one program, it is conceivable that each step is realized by a different program to communicate between processes. [0007] Also, in the method (2), for example, hardware such as a DSP (Digital Signal Processor: Digital Signal Processor) is used to perform accelerated processing (...
