A dual processor computer system with error checking includes a first processing system for executing a series of instructions including output instructions. A second processing system executes the series of instructions independently of and in synchronism with the first processing system. Shared resource devices are coupled to the first and second processing systems for receiving data from output instructions from the first and second processing systems substantially simultaneously. Error checking devices are located downstream of the shared resource means for checking the data received from the first and second processing systems only following a write operation into the shared resource means.

A dual processor computer system with error checking capability comprising: a first processing system for executing a series of instructions including output instructions containing data to be written into a designated system element; a second processing system for executing said series of instructions independently of and in synchronism with said first processing system; shared resource means, coupled to said first and second processing systems, for serving as a designated element for selected ones of said output instructions executed by said first and second processing systems and for recording the data contained in said selected ones of said output instructions, said shared resource means receiving said data from said first and second processing systems substantially simultaneously; and error checking means, coupled to said shared resource means and to said first and second processing systems, for checking the data received by said share resource means from said first and second processing systems for errors and for correcting said errors only when said selected ones of said output instructions are executed by said first and second processing systems to write data into said shared resource means.
