Abstract

PURPOSE:To shorten a communication time and to speed up control by adding a common address to respective controlled packages so as to transmit a control text. CONSTITUTION:A control package 1 and plural controlled packages 21-2n, all of which have processors, are connected by a communication path 3. An address 11 is extracted from the control text CT transmitted from a control package 1 in a control text reception part 21, and the address is compared with an address which has been set in an address setting part 23 in an address comparison part 22. When they coincide, s reception part 21 transmits a control command 12 to a command analysis part 24. When a global address is added to then control text CT as the address 11, respective controlled packages 21-2n receive them, and same control is attained by the one-time communication. Thus, the communication necessary time can be shortened and the speed up of control is realized.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a multi-processor system consisting of a control package having a processor and a plurality of controlled packages each having a processor. The present invention relates to a communication control method applied when a controlled package receives text.

[Conventional technology]

In such a multiprocessor system, each individual address is determined for each controlled package, and the control package sends the control text by specifying this address.This operation is performed for each controlled package. The control package sequentially controls each controlled package.

[Problem to be solved by the invention]

However, if the control package performs the same control on each controlled package, the control text must be sent to each controlled package, which increases the communication time required and causes a delay in control. is inviting.

[Means to solve the problem]

In order to solve the above-mentioned problem, the present invention is constructed by the following means.

That is, in the multiprocessor system described above,
The address setting section sets multiple addresses including a common address for each controlled package, compares the address in the incoming control text with the address of the address setting section, and receives the control text containing the matching address. Each controlled package is provided with an address comparator section for controlling the address comparison section.

[Effect]

Therefore, by adding a common address to each controlled package and sending the control text, the control package receives the control text at the same time in each controlled package. This can be done through communication.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to figures showing examples.

FIG. 2 is a block diagram showing the entire configuration, in which a control package 1 and a plurality of controlled packages 21 to 2n, each having a processor, are connected by a communication path 3. According to the control by the control package 1, each controlled package 2. .about.2n each execute a predetermined control process.

FIG. 3 is a diagram showing the structure of the control text sent by the control package 1, which includes an address 11 specifying the controlled package to be received and a control command 12).
The controlled packages 21 to 2n compare the address 11 in the control text with their own address, and when they match, determine that the control text should be received, and analyze the control command 12. In addition to doing so,
The content of this is meant to be funny.

FIG. 1 is a block diagram showing a control text reception processing circuit. In the control text CT (control text transmitted from the control package 1), an address 11 is extracted in the control text reception section 21 and is sent to the address comparison section 22. In addition, a comparison is made with the address set in the address setting section 23, and if they match, the address comparison section 22 gives this result to the control text reception section 21, so that the same reception section 2
1 sends the control command 12 to the command analysis section 24, the control command 12 is analyzed here, and the control text CT is thereby received.

However, in the address setting section 22, a plurality of addresses such as a global address common to each controlled package 21 to 2n and each individual address are set in advance, and the control text CT hegeglobal address is an address. 11, each controlled package 2
The address comparators 22 of □~2n are to produce matching outputs at the same time.4, each controlled package 21~2n
Since the control package 1 receives the CT (control text) all at once, the control package 1 can simultaneously perform the same control on each of the controlled packages 21 to 2111 by transmitting only one time.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, there is provided an address setting section in which a plurality of addresses including a common address are set for each controlled package, and an address in an incoming control text and an address in the address setting section. By providing an address comparison section that compares the addresses and receives the control text containing the matched address, if the control text is sent with a common global address added, this can be done simultaneously in each controlled package. Since the same control can be performed in a single communication regardless of what is being received, communication time can be shortened and control speed can be increased, resulting in remarkable effects in multiprocessor systems for various purposes. .
