Intelligent Neural Support Processor for Preventive Diagnosis And
Error Recovery

      This intelligent neural support processor (INSP) design
provides a better way to automatically perform preventive diagnosis,
recover faster faulty system component, and assure a better
reliability, availability and serviceability, thereby increasing
customer satisfaction.

      A sophisticated piece of INSP is responsible for automatically
performing preventive diagnosis, identifying faulty system components
for faster error recovery through reconfiguration whenever necessary.
It also allows switching system control to the other system if an
unfixed abnormality is detected.

      The scope of its application is from super computers,
mainframes and workstations to personal computers (depending on the
market analysis).  For purposes of discussion, the workstation is
particularly chosen to be the candidate to clarify the ideas at
implementation stages.

      The intelligent neural support processor could be either
implemented in hardware or software depending on the architecture of
the machine.  It is proposed to develop an INS processor as a
medium-scale VLSI-based virtual processor.  The INS processor
communicates to the common on-chip processor (COP) through serial bus
(COP BUS) with an existing common protocol.  The INS provides
functions like hardware debug for module and system, software debug,
running of architectural verification programs whenever necessary,
reading and comparing error logs with various available error
registers, preventing the discontinuation of job processing when
error occurs (by assigning to alternate chip - if hardware redundancy
exists - or by calling the recovery system manager to execute
functional recovery software programs; see Fig. 1), and more.

      In the INS processor, the unit analogous to the biological
neuron, is referred to as a processing element which has many input
paths (like dendrites) and combines the values of these input paths.
The combined inputs are then modified by a transfer function which
could be either a threshold function or a continuous functi...
