Method and system for dynamically loading processor application programs

Abstract

The invention relates to a technique for dynamically loading processor application programs and a hardware system for realizing the technique. The system mainly comprises a digital signal processor (DSP) 11, a field programmable gate array (FPGA) processor 17, a complex programmable logic device (CPLD) 16, a FLASH memory 13, a synchronous dynamic random access memory (SDRAM) 12, an interface chip14 and a power module 15, wherein fixed programs in the FLASH memory 13 comprise a DSP bootstrap program, a DSP management program and a plurality of FPGA and DSP application programs. A method for implementing the system has the characteristics that: dynamic loading and on-line updating of the FPGA application program and the DSP application program are realized by using the management program; the jump among the bootstrap program, the management program and the application programs is realized by the DSP technique so as to complete the dynamic loading function; and the FPGA is taken over bythe CPLD so as to configure a bus and the FPGA application program is loaded by combining the DSP.

Description

Processor application dynamic loading method and system thereof technical field The invention relates to a system capable of dynamically loading processor application programs and its implementation method. Background technique Functions such as land, sea, and air IFF, communication and navigation, electronic countermeasures, and missile tracking are all realized by independent electronic equipment, such as radio altimeters, IFF devices, TACAN equipment, and DME equipment. These discrete electronic devices all belong to the radio communication system, and their system configurations are similar, and their functions are realized by a processor that executes a specific application program. Typically, the processor may be a digital signal processor (DSP), a microcontroller such as an ARM processor, a field programmable gate array (FPGA), a PowerPC, or a general-purpose processor used in a PC. In these discrete electronic devices, the application program is placed in the ext...
