Computer with improved error handling in which hardware errors can be software corrected without the need for an expensive redesign as hardware errors can be trapped before they occur

摘要

Computer has an workflow controller with a program counter and an instruction decoder (4) for generating single instruction steps for a command that is to be executed. An error correction device (7) is connected to the flow controller and associated with it is a monitoring device (10), an error store (11) and an error handler (12). The error store includes known instructions that lead to errors, while the monitoring device compares the next instruction to execute with the known error instructions and if there is an agreement activates the error handler so that it undertakes appropriate counter measures.
