Problems solved by technology

The polling method first needs to occupy additional software address resources, and increases the design complexity of the CPU control bus (mainly involves increasing the access logic to the corresponding registers, and this usually makes the timing of the CPU control bus worse. )
Secondly, the software polling method will take up CPU computing time and affect CPU performance.

Embodiment 1

[0041] In order to facilitate signal broadcasting between functional modules in an integrated circuit, an integrated circuit is provided in an embodiment of the present application. See figure 1 as shown, figure 1It is a schematic diagram of the basic structure of the integrated circuit provided in the embodiment of this application. The integrated circuit includes:

[0042] Each functional module that needs to realize signal broadcasting, and a relay broadcasting network set between each functional module.

[0043] The relay broadcast network includes at least one relay broadcast module, and each functional module is connected to the relay broadcast module. At this time, each functional module together with the relay broadcast network constitutes a broadcast domain. After each functional module outputs a signal, the relay broadcast module that receives the signal broadcasts the signal to all functional modules connected to the relay broadcast network according to the conne...

Embodiment 2

[0086] On the basis of the first embodiment, this embodiment further illustrates the solution of the present application by taking several specific practical application scenarios as examples.

[0087] see Figure 7 The integrated circuit structure shown includes a master control module and multiple slave modules, all of which are connected to the relay broadcast network.

[0088] The relay broadcast network is composed of multiple relay broadcast modules connected to each other.

[0089] During the application process, the relay broadcasting modules in the relay broadcasting network can configure the mutual connection relationship according to the actual physical location. The master control module and multiple slave modules can be connected to any relay broadcast module, and the connection relationship can be determined according to the actual physical location between the modules, which is friendly to the back-end physical layout.

Abstract

The invention provides an integrated circuit, a broadcasting method of the integrated circuit, a relay module and electronic equipment, and the integrated circuit comprises a relay broadcasting network which comprises at least one relay broadcasting module; and at least two functional modules connected with one relay broadcast module in the relay broadcast network through a signal broadcast input interface and a signal broadcast output interface so as to realize signal broadcast through the relay broadcast network. Thus, the relay broadcast network is arranged to connect the functional modules, so that signal broadcast among the functional modules can be realized only through the relay broadcast module of the relay broadcast network, software intervention is not needed any more for signal broadcast among the functional modules, polling is not needed, and the CPU performance is not influenced; and meanwhile, the software address space is not occupied, so that the control bus design becomes simpler, and the control bus design complexity can be reduced.

Description

technical field [0001] The present application relates to the technical field of integrated circuits, in particular, to an integrated circuit, an integrated circuit broadcasting method, a relay module and electronic equipment. Background technique [0002] In traditional integrated circuit design, multiple functional modules (such as CPU (Central Processing Unit / Processor, central processing unit), DMA (Direct Memory Access, direct memory access) module, USB (Universal Serial Bus, universal serial bus) module etc.) often need to be implemented through software polling. The polling method first needs to occupy additional software address resources, and increases the design complexity of the CPU control bus (mainly involves increasing the access logic to the corresponding registers, and this usually makes the timing of the CPU control bus worse. ). Secondly, the software polling method will occupy CPU computing time and affect CPU performance. Contents of the invention ...
