Universal debugging interface-based SoC (System on Chip) hardware debugger

The invention discloses a universal debugging interface-based SoC (System on Chip) hardware debugger, which comprises a universal debugging interface, a TAP controller, a scan chain, a debugging control register module, a synchronizing module, a JTAG-AHB (Joint Test Action Group-Advanced High-performance Bus) protocol conversion module, an AHB-DMA (Advanced High-performance Bus-Direct Memory Access) module, an AHB bus controller, a debug support unit (DSU), an SoC peripheral module and a processor for supporting debugging. According to the universal debugging interface-based SoC hardware debugger, a JTAG port is applied to the DSU of a GAISLER laboratory open source for the first time, the scan chain is prevented from being plugged into a key path of the processor, and the structure and the performance of the SoC hardware debugger are superior to those of the normal hardware debugging modules at present. The SoC hardware debugger has beenis subjected to tape-out verification to prove that the function is corr
