Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not a limitation of the present invention.

[0024] Programmable logic device, namely PLD (programmable logic device), PLD is produced as a general integrated circuit, and its logic function is determined according to the user's programming of the device. The integration level of general PLD is high enough to meet the needs of designing general digital systems. In this way, a digital system can be "integrated" on a PLD by the designer's own programming, without having to ask the chip manufacturer to design and produce a dedicated integrated circuit chip

[0025] Such as figure 2 As shown, the present invention uses PLD as a switching module between the smartphone processor and peripheral devices, and can easily implement hardware for each external device through a hardware description language (VHDL, Very-High-Speed ​​Integrated Circuit Har...

Abstract

The invention discloses a programmable logic device for realizing a mobile phone hardware interface, which belongs to the technical field of mobile phone hardware interface, and includes a data sending part, a data receiving part, a clock frequency dividing part, a timing control part, an output buffering part and a registering part; The receiving part is connected to the timing control part, the data sending part is connected to the timing control part, the timing control part is connected to the output buffer part, the clock frequency division part is connected to the timing control part, and the register part is respectively connected to the data sending part and the data receiving part; the data sending part is also connected to the output Buffer component; the beneficial effect of the above-mentioned technical scheme is: through the programmable logic device, the user can customize the hardware interface of the mobile phone, expand the application range of the mobile phone interface, which greatly facilitates the development and design of the smart phone system; at the same time, the integrity of the high-speed signal Sex, compatibility of port level and improvement of driving ability all have a great improvement effect.

Description

Technical field [0001] The present invention relates to the technical field of mobile phone hardware interface, in particular to a programmable logic device for realizing the mobile phone hardware interface. Background technique [0002] In the hardware design of smart phones, it is often encountered that the development of many functions is restricted due to the limited interface resources of the hardware platform. In addition, peripheral devices such as display screens, cameras, touch screens, sensors and other peripheral devices are often encountered due to supply reasons or product demand changes caused by device changes, but these changes are often due to the inconsistency of the new device and the interface definition during hardware design. Or the lack of compatibility in the hardware design leads to corresponding major changes in the entire hardware design, wiring, and board manufacturing. [0003] However, the current smart phone hardware design on the market is mainly de...
