| 1. An interrupt control apparatus applied to a data processing system having a function of executing a conditional instruction
that executes a designated data processing when a designated branch condition of the conditional instruction is satisfied,
wherein a determination of the branch condition of the conditional instruction and the executed data processing when the branch
condition of the conditional instruction is satisfied are indivisible, said apparatus comprising:
a break detection section for detecting a breakpoint set at an arbitrary position of an instruction sequence;
a condition determination section for determining whether an instruction of a designated address as an instruction located
at an address specified as a break point address is executed as satisfying a branch condition of said conditional instruction;
and
a control section for controlling a break-interrupt based upon a breakpoint detection result from said break detection section
and execution of the instruction of the designated address according to a branch condition determination result from said
condition determination section.
