Title: Dsp pointer abnormality detection circuit
Inventor: SAKAI NOBUYUKI
IPC: G06F11/30
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To precisely detect the pointer abnormality by using a cycle change detection circuit, a same address detection circuit which detects the identity between the jumping destination address of a program execution instruction code and the address of contents of a program counter, and a decision circuit which decides the detection output of the decision circuit.

A same address detection circuit 30 detects that a program execution instruction code is equal to a jump instruction and also the jumping destination address is equal to the address of contents of a program counter 22. A decision circuit 40 detects that the detection output of the circuit 30 is not generated within a cycle of the input data and outputs this fact to the outside. In such a constitution, the pointer abnormality can be precisely detected without affecting the increase/decrease of execution steps nor expanding the execution instruction code.
