Which of the statement is true about alternative architecures?

Only explicit load and store instructions are permitted access to memory in CISC

machines

Specially designed hardware units, known as cache coherency monitors, monitor

inconsistencies in caches in a multiprocessor system

Superpipelining occurs when a pipeline has stages that require less than two

clock cycles to execute.

One problem with Flynn$\text{'}$s taxonomy is with the MIMD category; there are very

few, if any, applications for this type of architecture.

None of the above.
