[0043] The present invention will be further described in detail below in conjunction with specific embodiments, which are for explanation rather than limitation of the present invention.
[0044] The present invention is a SoC on-chip system, which is used for the access of the off-chip DSP to the on-chip peripherals of the SoC. At the same time, it provides a method for switching on-chip buses that can access and control the on-chip peripherals in a time-sharing manner by the DSP and the on-chip RISC processor. The DSP directly accesses the resources on the SoC chip, thereby realizing the data interaction mechanism between the DSP and the on-chip RISC processor through dual-port RAM. Improve the processing efficiency in the DSP+SoC computer system. The SoC on-chip system proposed by the present invention enables the DSP to access SoC on-chip resources through EMIF and can interact with the on-chip RISC processor. In order to realize the control of the on-chip peripherals by the...
