The Pentium FDIV bug is a hardware bug affecting the floating-point unit (FPU) of the early Intel Pentium processors. Because of the bug, the processor would return incorrect binary floating point results when dividing certain pairs of high-precision numbers.
Following the Pentium FDIV bug, the patchable microcode function took on a wider purpose to allow in-field updating without needing to do a product recall. [ 1 ] In the P6 and later microarchitectures, x86 instructions are internally converted into simpler RISC -style micro-operations that are specific to a particular processor and stepping level .
In late 1994, the Intel Pentium FDIV bug played out mailing list and in the newsgroup comp.sys.intel. The posters were acoumplished scientist and engineers from major companies. While Intel was claiming the bug was minor, the readers of these newsgroups found out how serious the defect was.
The Pentium (also referred to as the i586 or P5 Pentium) is a microprocessor introduced by Intel on March 22, 1993. It is the first CPU using the Pentium brand . [ 3 ] [ 4 ] Considered the fifth generation in the x86 (8086) compatible line of processors, [ 5 ] succeeding the i486 , its implementation and microarchitecture was internally called P5 .
President Trump has floated the idea of giving taxpayers a $5,000 refund check as a dividend from savings created by DOGE. Here's what to know.
In computing, Machine Check Architecture (MCA) is an Intel and AMD mechanism in which the CPU reports hardware errors to the operating system.. Intel's P6 and Pentium 4 family processors, AMD's K7 and K8 family processors, as well as the Itanium architecture implement a machine check architecture that provides a mechanism for detecting and reporting hardware (machine) errors, such as: system ...
