Dividing method and device of memory space of flash memory in field-programmable gate array

Abstract

The embodiment of the invention provides a dividing method and device of a memory space of a flash memory in a field-programmable gate array, and belongs to the technical field of field-programmable gate arrays (FPGA). The dividing method of the memory space of the flash memory in the field-programmable gate array includes the steps that an input number of storage spaces that the memory space of the flash memory in the FPGA is divided into is received, wherein the number is a natural number larger than 0; input sizes of all the storage spaces are received; according to the received number of the storage spaces and the received size of each storage space, the memory space of the flash memory in the FPGA is divided correspondingly. The starting address of each storage space is stored in a register. By the adoption of the dividing method and device of the memory space of the flash memory in the field-programmable gate array, the technical problem is solved that the sizes and number of thestorage spaces are limited, the convenience and flexibility of FPGA data storage are significantly improved, space waste caused by a traditional FPGA memory space dividing method based on parallel FLASH is thoroughly avoided, and the cost of a FPGA system is significantly reduced.

Description

technical field [0001] The invention relates to the technical field of field programmable gate array FPGA, in particular to a method and device for dividing the storage space of flash memory in the field programmable gate array. Background technique [0002] Field Programmable Gate Array (FPGA: Field-Programmable Gate Array) is becoming larger and larger, which puts forward higher requirements for the convenience of FPGA data storage and the cost of the system. Among many FPGA data storage methods, based on flash memory ( FLASH) FPGA data storage method, compared with other FPGA data storage methods, has been widely used due to its user-friendliness and lower system cost, and has become the mainstream FPGA data storage method in the industry. [0003] At present, based on the FPGA storage space division method of parallel FLASH, the FPGA divides the parallel FLASH into 2, 4, 8, 16 equal-sized 2 by controlling the high address of the parallel FLASH. n share. The size and qu...
