Abstract

A Programmable Logic Device (PLD) and an access method thereof are provided. The PLD includes: a power supply (10), a PLD module (20) and a flash (30). The power supply (10) is for providing a work power supply to the PLD module (20) and the flash (30); the flash (30) is for storing data needed by the PLD module (20) and / or an external processor (50), and for allowing the PLD module (20) and / or the external processor (50) to access the data. The PLD could reduce the area of the single board of a PCB effectively, save the cost, enable the hardware design to be more integrated and the usage to be more convenient, and be adapted to the application situation of the communication system hardware realization, which needs the simultaneous usage of the FLASH memory and the PLD.

Description

technical field [0001] The present invention relates to the communication field, in particular to a programmable logic device and an access method thereof. Background technique [0002] In the field of integrated circuits, with the increasing miniaturization of electronic components and the continuous improvement of integrated circuit technology, chip miniaturization and integration have become a trend, because the higher the degree of chip integration, the smaller the product volume , the lighter the weight, the more convenient the design, the better the stability and the lower the cost. [0003] In the hardware implementation process of communication equipment, it is often necessary to use FLASH (flash memory) storage devices and programmable logic devices (Programmable Logic Device, PLD) at the same time. Among them, FLASH storage devices are mainly used to store the startup code and file system of the processor. To ensure that the processor startup code is not lost when...
