Embodiment 1
[0026] This embodiment provides a digital signal processor DSP loading method, such as figure 2 As shown, the method includes:
[0027] Step A1: the DSP receives the signal sent by the field programmable gate array FPGA to notify the DSP to perform initialization;
[0028] Step A2: The DSP obtains the reset configuration word RCW stored in the FPGA according to receiving the signal notifying the DSP to perform initialization;
[0029] Step A3: The DSP configures the hardware resources of the DSP according to the acquired RCW.
[0030] Through the description of the above steps A1 to A3, the DSP realizes its own loading, that is, the configuration of its own hardware resources. The embodiment of the present invention realizes a method for loading a digital signal processor DSP. By this method, no Add an independent storage device, such as EEPROM, to store RCW, but store RCW in FPGA by acquiring. Since the FPGA can be controlled by the CPU, the update of the RCW stored on th...
Embodiment 2
[0032] An embodiment of the present invention provides a DSP loading method for a digital signal processor. In order to facilitate the understanding of a DSP loading method provided by the embodiment of the present invention, first of all image 3 A device including at least a CPU module, a Flash module, an FPGA module and a DSP module is shown for illustration. In order to make the FPGA module and the DSP module work normally, it is necessary to load the DSP module and the FPGA module respectively, so that the device can work normally. In this device, the communication between the CPU module and the FPGA module is carried out through the local bus (Local Bus). 2 The EEPROM of C or SPI interface, the EEPROM in the FPGA passes through I 2 The C or SPI interface communicates with the DSP. After the FPGA completes its own configuration, it loads the stored RCW into the DSP to realize the DSP loading RCW.
