Micro computer and method of optimizing microcomputer

A microcomputer comprising:

• a circuit block;
• a nonvolatile memory configured to store optimization data for optimization of an operation of said microcomputer;
• and
• an optimization circuit configured to read out memory optimization data as a part of said optimization data from said nonvolatile memory in response to a first frequency clock signal and to optimize an operation of said nonvolatile memory based on said memory optimization data;
• and then to read out circuit block optimization data as another part of said optimization data from said nonvolatile memory in response to a second frequency clock signal and to optimize an operation of said circuit block based on said circuit block optimization data, and
• wherein a frequency of said first frequency clock signal is lower than that of said second frequency clock signal.

A method of optimizing a microcomputer, comprising:

• generating a first clock signal until the optimization of said microcomputer is completed;
• reading out memory optimization data as a part of optimization data for optimization of an operation of said microcomputer from a nonvolatile memory in synchronization with a first frequency clock signal of said first clock signal to optimize an operation of said nonvolatile memory;
• reading out circuit block optimization data as another part of said optimization data from said nonvolatile memory in synchronization with a second frequency clock signal of said first clock signal to optimize an operation of a circuit block;
• and
• generating a second clock signal after the optimization of said microcomputer is completed,
• wherein a frequency of said first frequency clock signal is lower than that of said second frequency clock signal, and
• a CPU operates in response to said second clock signal.
