[0046] The present invention will be further described in detail below in conjunction with the drawings.
[0047] According to the content of the above invention, the present invention is a digital signal processor emulator based on PCI interface and JTAG interface. The emulator is used in the digital signal processor debugging system, interconnected with the debugging host through the PCI board (PCI interface), and interconnected with the target processor through the JTAG interface. It contains the above two interface control logic and the main controller unit. The main controller unit contains DMA controller logic and macro instruction analysis logic. By using DMA operation, the interactive speed and simulation speed of debugging data can be greatly improved. The use of macro instruction analysis operation facilitates the development of simulation software of the debugging host and enhances more simulation debugging functions.
[0048] As shown in Fig. 2, the emulator provided b...
