| Outline of Final Research Achievements |
uClinux for 32bit computer has successfully worked on tiny 8bit CPU on FPGA. A physical layout of the tiny CPU with only 10000 transistors has been completed. An instruction level workaround technique for bypassing hardware defects, PPC (Partially Programmable Circuit) technique for bypassing logic defects, hardware level defect detector without TMR (Triple Module Redundancy) and reconfiguration technique for defect isolation are established. A dependable FU array accelerator has been designed and the high-dependability has been observed by error injection with an alpha-particle generator.
