No.2（1999）23.Design of selfchecking microprocessors by coding

Taku SONODA, Hisanao MORI, Kazumi SAKAMAKI and Takeshi KANAOKA

Microprocessors are indispensable to control systems such as industrial machines. However standard microprocessors are hardly designed fail-safe, and the need for reliable microprocessors against errors and hardware failures are increasing. In this paper, the design of self-checking microprocessors which used hamming code as error-detecting and error-correcting code to detect errors in DATA-BUS was proposed.Also, these self-checking microprocessors can be redesigned for user's needs because they are designed by VHDL.
