The Intel Pentium is a fifth-generation x86 architecture
microprocessor. It is the successor to the
486.
The Pentium was originally to be named 80586 or i586, but the
name was changed to Pentium because numbers could not be
trademarked.
The original Pentium microprocessor had the code name P5, and
was the first Superscalar Cisc microprocessor, produced at
0.8 um.
Early versions of the P5 had a problem in the floating point
unit that, in rare cases, resulted in reduced precision of
division operations. This bug, discovered in 1994, became known
as the Pentium FDIV bug. The 60 and 66 MHz 0.8 um versions of
the Pentium processors were also known for their fragility and
their (for the time) high levels of heat production |
