Embodiment 1
[0046] figure 1 It is a flow chart of an inter-board control method provided by Embodiment 1 of the present invention. This embodiment is applicable to the control and communication between the common board and the collection board of multi-type service collection equipment. The method can be controlled by the inter-board control device To execute, specifically include the following steps:
[0047] Step S110: Obtain the target address of the control target located on the acquisition board from the address space of the common board at a set period.
[0048]The multi-type business acquisition equipment in this solution is provided with a common board and an acquisition board. The common board includes a central processing unit and a core processing chip. The central processing unit and the core processing chip of the common board are connected through the A / D Bus. D Bus contains 16-bit address bus, 32-bit data bus, read signal, write signal and chip select signal. The core pro...
Embodiment 2
[0056] figure 2 It is a flow chart of an inter-board control method provided in Embodiment 2 of the present invention, which specifically includes the following steps:
[0057] Step S210: Obtain the target address of the control target located on the acquisition board from the address space of the common board at a set period.
[0058] In this scheme, all the signals of the inter-board control bus between the common board and the acquisition board are connected one-to-one, and there is no situation where one signal drives multiple loads, which avoids reading and writing sharing a signal line and a pair of The problem of uncertain signal status under multi-mode and different load conditions.
[0059] In addition, the signal rate of this bus is 32.768Mbit / s, and there are only 15 effective control signals corresponding to one slot. In actual products, ordinary 64-core European sockets are used for connection, and there are no special requirements in terms of design and product...
Embodiment 3
[0073] image 3 It is a structural block diagram of an inter-board control device provided by Embodiment 3 of the present invention. This embodiment is applicable to the control and communication between the common board and the collection board of multi-type service collection equipment.
[0074] Such as image 3 As shown, the inter-board control device includes:
[0075] The address obtaining unit is used to obtain the target address of the control target located on the acquisition board from the address space of the common board according to the set cycle;
[0076] An instruction sending unit, configured to send a control instruction to the target address through the dual-port RAM in the mapping register set of the common board;
[0077] An instruction response unit, configured to respond to the control instruction based on the control target corresponding to the target address.
[0078] Optionally, the instruction sending unit includes:
[0079] The instruction sending...
