cache is the problem occurs in processor
The Intel Pentium bug was an issue with the Floating Point Unit (FPU), which is a section of the processor that performs floating-point calculations.The FPU bug only occurred on earlier Intel Pentium processors, which Intel replaced with fully functional processors.
An FPU or floating point unit is the part of the microprocessor that does math.
A processor (if you are talking about the CPU (central processing unit)) consists of numerous transistors--sometimes millions. An Intel Pentium D has 230,000,000. There are no microprocessors in it since it is a microprocessor in and of itself.A microprocessor doesn't have to be a CPU, but can have a specific function such as graphics processing, sound processing, or FPU (floating-point unit). Of course, many of these separate microprocessors are no longer independent chips.
No, it is a 32-bit processor in the sense of using 32-bit virtual addresses and having 32-bit general purpose registers and ALU that operates on those 32-bit GPRs. It does feature "MMX Technology", which can process 64-bits of information at a time by reusing the FPU's registers, however, in the more common usage, it is not considered a 64-bit processor due to the lack of 64-bit virtual address space and 64-bit GPRs.
* Data/Instruction Cache - An 8192-byte SRAM built into the processor core, designed to store the most commonly used instructions. The 386 supported an off-chip cache, but this was much slower. * Pipelining - This allows the processor to handle a Locate-Fetch-Execute each clock cycle. The pipeline is offset meaning the execute step required information from the previous two clock cycles. A locate would feed the next fetch, the fetch would feed the next execute. The 386 needs to do each step separately. * Improvements to MMU performance. * Integrated FPU - (DX models only) Added accelerated high end math functions.
Floating Point Unit
In some cases, Graphics Processing Units (GPUs) are integrated into CPU to handle video processing tasks more efficiently. GPUs can sometimes be used for more general processing in some cases.Another commonly integrated processor is a Floating Point Unit (FPU), which is more commonly known as a math coprocessor. While a CPU can do its job, the FPU is more efficient because it has specialized hardware and its functions are not derived from code or microcode.In the common sense, processors in addition to the main CPU are known as coprocessors.
To enable the FPU Compare hack in PCSX2, go to the "Emulation" tab and select "Configure." Under the "Settings" menu, navigate to the "Game Settings" section and find the "Advanced" tab. Here, you will see an option for the FPU Compare hack; check the box to enable it. After making your changes, click "OK" to save the settings and improve compatibility for certain games.
Just wait my dear, I have prepared a comprihencive answer of ur questions. When u make friendship with camles, u must keep ur doors of their size. Abbas
FPU stands for Floating Point Unit. It is a specialized part of a computer's central processing unit (CPU) responsible for handling calculations involving floating-point numbers, which are numbers with decimal points or numbers that require very high precision calculations.
Yes, it is fundamental to the operation of even the most basic CPU. ALU stands for Arithmetic Logic Unit. It is the part of the processor which deals with basic logic and mathematical operations (not to be confused with an FPU, which performs more complex calculations of the same nature in a floating point representation). ALUs can be as simple or complex as necessary.
The arithmetic and logic unit (ALU) within the computer's central processing unit (CPU) carries out arithmetic operations. Some designs also support a dedicated floating-point processing unit (FPU), which carries out arithmetic, trigonometric and logic operations based on floating-point variable types.
