Claims

[Claims for Utility Model Registration] A CPU running state analyzer that observes the running state of a program installed in a microprocessor (CPU), which analyzes each address range where tasks (or routines) of the program are located. A preset setting section, an address comparator section that inputs the address from the CPU and set address information from the setting section, and detects that the set address has been accessed, and an address comparator section that selects the content of the CPU access and performs the selected access. a display selection section that outputs a latch clock when 1. A CPU running state analyzer comprising: a CPU running state analyzer, which is capable of grasping which task a CPU is executing;
