Abstract

The invention provides a method for realizing online debugging on application codes of a 51 soft core. The method comprises the following steps: by modification of the 51 soft core and a Monitor-51, merging an independent external data space of the 51 soft core with a code space to form a unified readable-writable external memory space RAMx and generate an FPGA (field programmable gate array) configuration data file containing the 51 soft core; downloading the FPGA configuration data file containing the 51 soft core into an FPGA, thereby realizing online debugging on the application codes of the 51 soft core. The method is practical and feasible; the development period of a programmable system-on-chip based on the 51 soft core is shortened greatly; and the method is applicable to MC8051 cores and other 51 soft cores.
