Supplying central processor with instruction data for fast microprocessor, micro-controller and signal processor

摘要

The central processing unit (1) takes the prepared instruction data from a memory (2). The CPU selectively acquires the instruction data read from the memory or other, neutral instruction data. The neutral data is defined instruction data which causes no operations in the CPU unit, or which causes an operation which has no significant effect on the execution of the program being run by the central unit. The neutral data is permanently available or is very rapidly accessed from a separate memory or generation device.
