Chip debugging device, debugging method and SOC (System of Chip) chip system

Abstract

The invention discloses a chip debugging device, a debugging method and an SOC (System of Chip) chip system. The chip debugging device is characterized in that a conversion module carries out serial-parallel conversion on input debugging command data; an analysis module analyzes the debugging command data after serial-parallel conversion into an AMBA (Advanced Microcontroller Bus Architecture) bus command and obtains executive result data obtained by a chip through executing the AMBA bus command, so that a function module in the chip is accessed according to the AMBA bus command, read and write operations are carried out on the function module in the chip and an operation result is returned to the conversion module; and the conversion module outputs the operation result after serial-parallel conversion to complete debugging of the chip. In comparison with the prior art, a chip debugging process of the chip debugging device provided in the embodiments of the invention does not need participation of a CPU (Central Processing Unit), CPU resources are not occupied, and the chip is debugged based on the AMBA bus command, so that the function module in the SOC chip can be debugged, and thus the integrity of chip debugging is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a chip debugging device, a debugging method and an SOC chip system. Background technique [0002] The SOC (System of Chip) chip contains a CPU (Central Processing Unit), which connects at least two functional modules through a parallel bus. In the development process of the SOC chip, in order to achieve different functions, different functional modules need to be integrated. Inside the SOC chip After the architecture of the SOC chip is built, it is necessary to debug the functional modules inside the SOC chip. [0003] Existing chip debugging scheme: for example scheme 1 (patent application number: CN201010593731.3), such as figure 1 As shown, the chip debugging equipment includes an upper machine position and a hardware debugging tool; the upper machine position is connected with the hardware debugging tool through a general-purpose port, and the hardware debugging tool ...
