Abstract

The invention provides a remote dynamic loading system and method for a processor program on the basis of an FPGA or a CPLD controller. The system comprises an upper computer, a communication unit, an FPGA or a CPLD controller unit, a processer unit and a parallel volatile storage unit, wherein the processor program is stored in the upper computer, the program and a control command are packaged into data frames, identifiers are added, and the data frames are transmitted to the communication unit; the communication unit receives the program and the control command from the upper computer and sends the program and the control command to the FPGA or CPLD controller unit; and the FPGA or CPLD controller unit manages an external bus of the processer unit and receives the data frames from the communication unit at the same time, writes the program into the parallel volatile storage unit according to identifiers and contents of the data frames, and controls the processor to jump to an address where the program is in and start working. According to the system and the method, remote and dynamic loading is performed on the processor on the premise that a storage is not subjected to flash curing.

Description

technical field [0001] The invention relates to the technical field of digital circuit data processing and transmission, in particular to a system and method for remote dynamic loading of processor programs. Background technique [0002] The domestic oilfield ground equipment system is generally composed of multiple signal processing boards. The system hardware configuration of different types of signal processing boards is similar, and the processor executes specific application programs to realize its different functions. [0003] Usually, most of the loading modes of signal processing boards are solidified by program flash, which realizes a single function and cannot dynamically configure, increase and change its functions according to needs. Therefore, the equipment requires a large number of signal processing boards, which are costly and inconvenient to carry. [0004] If the program of the signal processing board can be dynamically loaded by the upper computer, and the...
