One-instruction set computer

<p>A one-instruction set computer (OISC), sometimes referred to as an ultimate <a href="/facts/RISC/aQbGM62p">reduced instruction set computer</a> (URISC), is an <a href="/facts/Abstract_machine/zuC4RKLn">abstract machine</a> that uses only one instruction – obviating the need for a <a href="/facts/Machine_language/bgdQ1Fxf">machine language</a> <a href="/facts/Opcode/UaLMp56C">opcode</a>. With a judicious choice for the single instruction and given arbitrarily many resources, an OISC is capable of being a <a href="/facts/Universal_computer/ojCtglYu">universal computer</a> in the same manner as traditional computers that have multiple instructions.: 55  OISCs have been recommended as aids in teaching computer architecture: 327 : 2  and have been used as computational models in structural computing research. The first <a href="/facts/Carbon_nanotube_computer/JqUVUBYz">carbon nanotube computer</a> is a <a href="/facts/1-bit_computing/ArKvhVbw">1-bit</a> one-instruction set computer (and has only 178 transistors).
