CPU must be continuously fed with instruction and data; this problem is
known as the von Neumann bottleneck. (2) The architecture is inherently
sequential ; this concept is known as Single Instruction Single Data (SISD).
Despite the above drawbacks, no other architectural computer concept
has found a similar widespread use in nearly 70 years of digital electronics
(Hager and Wellein 2011).
In the past, generic computer systems were big, energy demanding
and expensive. Such drawbacks were bigger for scientifi c computers
because this kind of ...
