Description

Technical Field

Background

The CPLD (Complex Programmable Logic Device) adopts CMOS (Complementary Metal Oxide Semiconductor) EPROM (Erasable Programmable Read Only Memory), EEPROM (Electrically Erasable Programmable Read Only Memory), flash Memory, SRAM (Static Random Access Memory), and other programming technologies, thereby forming a high-density, high-speed, and low-power Programmable Logic Device. The method is easy to realize various algorithms and combinational logic functions, has the advantages of no power failure loss configuration, convenient upgrading and the like, and is widely applied to communication equipment.

Currently, a server device in the market usually uses a CPLD as an auxiliary system to assist a Central Processing Unit (CPU) in system control, such as controlling functions of a power-on timing sequence, an LED lamp, turning on and off, and resetting. As shown in fig. 1, the existing server mainly includes a CPU10, a bridge piece 20, and a CPLD30, where the CPU10 is communicatively connected to the bridge piece 20, and the bridge piece 20 is communicatively connected to the CPLD 30. The CPU10 has information communication with the bridge 20, and the bridge 20 transmits information to the CPLD30 through GPIO (General-purpose input/output), so that the CPLD30 is used to assist the CPU10 in system control. However, the auxiliary system using CPLD has the following disadvantages:

1. when burning new firmware, a professional burner is required to be used for wiring burning, and online burning cannot be carried out.

2. The CPLD has limited storage space and cannot execute too complicated programs; the CPLD is composed of a plurality of logic gates, different CPLD devices are required to be selected according to different functional requirements, but the number of the logic gates is limited, so that the functions which can be realized are limited, and complex functions cannot be realized. For example, a function of a long time delay, for example, a time delay of 500ms, cannot be realized. This function cannot be achieved because the CPLD may not provide enough logic gate resources because the longer time delay would occupy more logic gates.

3. The CPLD generally uses VHDL (Very High Speed Integrated Circuit Hardware Description Language) for programming, but VHDL programming is not the mainstream programming method and the programming difficulty is large.

4. The CPLD adopts GPIO to acquire information from the bridge chip only in one direction, can only execute simple control and cannot realize information interaction.
