As the name suggest, this category of computing devices has only one instruction in its instruction set. At a first glance, this may seem impossible and you may think over how a minimum of two distinct symbols are needed to represent an information (in connection to binary numbers).
One Instruction Set Computer (OISC) (also known as ultimate reduced instruction set computer (URISC)) is a computer architecture that has only one instruction in its instruction set.
Read this article to understand the working of OISC using an example
There are three approaches to implementing OISC:
- Bit-manipulating machines
- Transport triggered architecture machines
- Arithmetic-based Turing-complete machines
