Title: Data processing unit, data processing device and control method
Inventor: SATO TAKESHI
IPC: G06F9/48
Filed: 2000-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a data processing unit which enables speedy transition of an address based on an interruption request from a processing unit on the same chip. SOLUTION: The data processing unit comprises a register 18 for external specification which can set a new transition address on PU2 directly from VU3 in a system LSI fitted with the general-purpose data processing unit PU2 and the special-purpose data processing unit VU3. Interruption processing is implemented by outputting a transition address B1 set in the register 18 for external specification against an interruption request signal ϕ2 from VU3, so a transition address is altered or specified dynamically upon receipt of an interruption signal while conventionally interruption has been made possible by rewriting a transition address with software. This enables real time transition dependent on factors of other processing units to be implemented very flexibly.
