With what part of the CPU was the Intel Pentium bug an issue?

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.

What type of processor is sometimes integrated with the CPU to handle certain tasks more efficiently such as video processing?

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.

Why do math coprocessors enhance the capabilities of an ordinary CPU?

They simply make it easier to do floating point instructions.Before the 486 computers, math processors (or floating point units) in IBM compatibles were optional. The 486DX was the first CPU to include a floating point set as standard equipment. Intel did release the 486SX which was much like the 386DX, which had no floating point set.Most of the older programs that required floating point instructions were compiled with floating point libraries. These were instructions that used the CPU to emulate a math coprocessor. The software would call the floating point command just like the coprocessor was there. The CPU would throw an exception that it didn't understand the command, then the exception handler would send the command to the floating point library which would then execute it.But these routines were slow and the CPU had to be tied up to run them. A lot of the floating point libraries also had floating point processor detection routines. So if a math coprocessor was detected, then all the software interrupts used by the emulator sets would be routed to the math coprocessor. So when the CPU refuses to execute an instruction, the coprocessor takes over.In certain cases, the CPU can continue with the next instructions while the FPU is busy if there is no risk of a race condition. A race condition is when there is a chance that the result might not be there when it is needed. For instance, you don't want the CPU to process the results of the FPU before the results arrive, or the CPU will get random garbage from memory and act the next instruction upon the garbage. Then the FPU puts its result in that area of memory too late. So one way around that is the FWAIT instruction. That pauses the CPU while the FPU finishes to prevent a race condition.


Is The ALU part of the CPU?

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.


Can unemployment benefits be garnished by a creditor in Indiana?

I JUST spoke to a person that is part of Dave Ramsey's Financial Peace University - a certified consultant/counselor and he stated that creditors cannot garmish unemployment checks or the wages earned via an unemployment claim. Additionally, when I spoke to the main FPU number in TN, the counselor online stated that creditors cannot garnish SS and disability pensions/wages, either.
