Abstract

The invention relates to a method for automatic program programming of multiple DSP chips, wherein a serial bus is used to implement data communications between an upper computer and a processor with the multiple DSP chips. The method comprises the steps that (S1) the upper computer sends an instruction for starting programming a DSP chip program to the processor, and a to-be-programmed data document is transmitted to the processor via the serial bus; (S2) the upper computer conducts automatic program programming of a main DSP chip by an FPGA unit in the processor, and monitors an intermediate state of the programming; (S3) the upper computer conducts automatic program programming of subordinate DSP chips by the FPGA unit in the processor and the main DSP chip, and monitors an intermediate state of the programming; and (S4) the step (S3) is executed repeatedly till the automatic program programming of all the subordinate DSP chips is completed. According to the invention, the automatic program programming of a batch of DSP chips can be achieved; and the whole programming course can be monitored in real time, so accuracy can be ensured.

Description

technical field [0001] The invention relates to a method for automatically programming a processor with multiple DSP chips, in particular to a method for automatically programming a batch of DSP chips. Background technique [0002] In the process of batch debugging of processors, the programming of DSP (Digital Signal Processing, digital signal processing) chips is a time-consuming and laborious program. More importantly, whether the programming of DSP chips is correct or not will directly affect Whether the processor can work normally. In the prior art, the manual programming method is generally used, and the debugger needs to manually load the data files to be programmed. After the programming is completed, it is necessary to send instructions by operating various signal sources to verify whether the programming is correct. For a single DSP chip, manual programming is still feasible. But for batch DSP chips, manual programming will greatly affect the efficiency and accur...
