− | The '''TMS1000 Series''' | + | The '''TMS1000 Series''' was a [[microprocessor family|family]] of [[4-bit architecture|4-bit]] [[microprocessor]]s designed and manufactured by [[Texas Instruments]] in the early 1970s. Originally made using [[pMOS logic|pMOS]] technology, TI later expended the family into [[nMOS logic|nMOS]] and [[CMOS]]. These microprocessors are considered to be the first single-chip microprocessors in the world. However, unlike the [[Intel 4004]], it was not released to general market until 1974. |

It was the first microprocessors ever created, designed by [[Texas Instruments]] engineers Gary Boone and Michael Cochran. Gary patented the invention on Aug 31, 1971. On Sep 4, 1973, he was awarded [http://www.google.com/patents/US3757306 U.S. Patent 3,757,306]. Unlike Intel's chips, TI's was not placed into the general market until 1974. Instead TI used the chip for their calculators.<ref name=smithsonianchips>[http://smithsonianchips.si.edu/augarten/p38.htm The Most Widely Used Computer on a Chip The TMS 1000]</ref> |

The TMS 1000 had a relatively simple design with only 43 instructions and 2 general purpose registers. Similar to the [[Intel 4004]], the chip only had a single level of stack and no interrupts. | The TMS 1000 had a relatively simple design with only 43 instructions and 2 general purpose registers.
