Abstract
An exemplary aspect of the present invention is a data processing system, including a function block that operates based on a clock, a clock supply control circuit that controls supply of the clock based on an enable signal, a storing part that stores a command table in which a debug command and a number of clocks needed to process the debug command by the function block are made correspondent to each other, and a debug system part that executes debug processing based on an input debug command, in which the debug system part refers to the command table and outputs the enable signal in accordance with the number of clocks corresponding to the input debug command.
Claims8
A data processing system, comprising:
- a function block that operates based on a clock;
- a clock supply control circuit that controls supply of the clock based on an enable signal;
- a storing part that stores a command table in which a debug command and a number of clocks needed to process the debug command by the function block are made correspondent to each other;
- and
- a debug system part that executes debug processing based on an input debug command, wherein
- the debug system part refers to the command table and outputs the enable signal in accordance with the number of clocks corresponding to the input debug command.
A debug method of a device comprising a function block that operates based on a clock, the method comprising:
- stopping a clock signal;
- referring to a command table in which a debug command and a number of clocks needed to process the debug command by the function block are made correspondent to each other to supply the clock signal in accordance with the number of clocks corresponding to an input debug command;
- and
- executing debug processing based on the input debug command.
