Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] In the FPGA+DSP architecture design scheme adopted in the present invention, DSP start-up related codes are generally stored in an external memory, and DSP initialization needs to obtain data from the external memory to complete start-up related configurations. The FPGA of the present invention can set the start mode of the DSP by controlling the GPIO pins related to the start mode of the DSP, and the DSP can automatically obtain the start configuration value from the corresponding external memory to complete the start of the DSP.

[0031] This method is based on the characteristics of FPGA rewritable and reprogrammable, and can flexibly configure related DSP initialization requirements. The technical solution adopted by the present invention to solve related technical problems is: a method for flexible configuration of DSP initialization based on FPGA...

Abstract

The invention relates to a method for configuring DSP initialization, which adopts an embedded FPGA + DSP structure, and an FPGA completes the DSP initialization configuration before a DSP works. Themethod comprises the steps of DSP power supply initialization, the clock initialization, the reset initialization and the DSP start-up mode configuration. The method of configuring DSP initializationof the invention adopts the FPGA programmable characteristics, can configure different DSP initialization requirements, can save external hardware resources, and is relatively simple to realize.

Description

technical field [0001] The invention belongs to the field of electronic information application, and in particular relates to a method for configuring DSP initialization. Background technique [0002] With the rapid development of embedded technology, the field of embedded applications is becoming more and more extensive, and higher and higher requirements are put forward for embedded related technologies. In the field of embedded applications, especially data processing, the demand for data is relatively large, and the processing results require high real-time performance. On this basis, DSP solutions are often used. DSP chips have powerful computing capabilities, fast processing speed, and can complete complex calculations, which can meet the needs of embedded applications. For the development of common DSP application fields, DSP initialization is a problem that often needs to be solved in development. According to different application requirements, different types of ...
