The FPU (Floating Point Unit) maths co-processing capability is available on all x86 processors since the 80486DX series. The FPU and MMU instruction sets (for the x86 family) have not been considered supplementary instructions since their introduction due to their importance to core CPU functionality.
The Intel 8231 (and revised 8231A) is the Arithmetic Processing Unit (APU). It offered 32-bit "double" precision (a term later and more commonly used to describe 64-bit floating-point numbers, whilst 32-bit is considered "single" precision) floating-point, and 16-bit or 32-bit ("single" or "double" precision) fixed-point calculation of 14 different arithmetic and trigonometric functions to a ...
A floating-point unit (FPU), numeric processing unit (NPU), [1] colloquially math coprocessor, is a part of a computer system specially designed to carry out operations on floating-point numbers. [2] Typical operations are addition , subtraction , multiplication , division , and square root .
In this case, no variation in Y can be accounted for, and the FVU then has its maximum value of 1. More generally, the FVU will be 1 if the explanatory variables X tell us nothing about Y in the sense that the predicted values of Y do not covary with Y. But as prediction gets better and the MSE can be reduced, the FVU goes down.
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.
One PCI Express port (x8 1.0) vs. the T1's JBus interface Two Sun Neptune 10 Gigabit Ethernet ports (embedded into the T2 processor) with packet classification and filtering L2 cache size increased to 4 MB (8-banks, 16-way associative) from 3 MB
Lazy FPU state leak (CVE-2018-3665), also referred to as Lazy FP State Restore [1] or LazyFP, [2] [3] is a security vulnerability affecting Intel Core CPUs. [1] [4] The vulnerability is caused by a combination of flaws in the speculative execution technology present within the affected CPUs [1] and how certain operating systems handle context switching on the floating point unit (FPU). [2]
The CPU core is a two-way superscalar in-order RISC processor. [3] Based on the MIPS R5900, it implements the MIPS-III instruction set architecture (ISA) and much of MIPS-IV, in addition to a custom instruction set developed by Sony which operated on 128-bit wide groups of either 32-bit, 16-bit, or 8-bit integers in single instruction, multiple data (SIMD) fashion (e.g. four 32-bit integers ...
