Abstract

The invention discloses a module for starting multiple user programs by a single Flash. The module is characterized by comprising one programmable device and one FLASH chip connected with the programmable device, wherein multiple user program storage regions and one public program storage region are divided in the FLASH chip, each user program storage region stores one corresponding user program, and the public program storage region stores one corresponding EEPROM (Electrically Erasable Programmable Read-Only Memory) program; the programmable device can accept the access of multiple CPUs (Central Processing Units) and one FPGA (Field Programmable Gate Array) in parallel, thereby realizing that the public program storage region in the FLASH chip corresponds to the FPGA, and each user program storage region respectively corresponds to one CPU; and a bus switching module is designed in the programmable device, and the bus switching module can orderly transmit the user programs in the user program storage regions of the FLASH chip to the corresponding CPUs and transmit the EEPROM program to the corresponding FPGA.

Description

technical field [0001] The invention relates to computer startup technology, in particular to a single-chip FLASH startup multi-user program module. This module is mainly used in digital systems for processing large amounts of data, such as image recognition, signal analysis and other fields. Background technique [0002] With the rapid development of information technology, intelligent automatic control system has become a trend. The storage and loading of preset programs have become unavoidable problems for each intelligent automatic control system. The memory of RAM nature cannot meet the requirement of not losing data when power is off. Only ROM-type devices can support data not losing after power off, among which FLASH is widely used for program storage of embedded systems. In a single CPU digital system, a CPU chip needs a FLASH to store programs for it. If a field programmable gate array (ie FPGA) needs to be used in the system, a dedicated EEPROM is required as th...
