Can real number arithmetic be done without the use of a coprocessor?
Of course! People were doing real arithmetic long before the first computer!
What is the standard IRQ setting for a math coprocessor?
What is the standard IRQ setting for a math coprocessor?
How does a coprocessor work?
A coprocessor is a specialized computer chip that works alongside the main processor to handle specific tasks more efficiently. It offloads certain computations from the main processor, enabling faster processing speeds and better overall system performance. Coprocessors are often used for tasks like floating-point arithmetic, encryption, and graphics processing.
How can you find out what coprocessor you have?
Modern computers typically do not use a coprocessor. Floating-point capabilities are built into the CPU.
What is the first CPU to include an internal math coprocessor?
486SX
Is there microprocessor with the name 80487?
No. An 80487 would have been a math coprocessor for an 80486 general-purpose microprocessor...just like the 8087 was the math coprocessor for the 8086 and 8088, the 80287 for the 80286, and the 80387 was for the 80386. The 80486 was the first Intel processor to contain an on-chip math coprocessor, so there wouldn't have been an 80487 because it wasn't necessary.
How does the 8087 coprocessor work?
the 8087 is a numeric data processor(NDP) it is basically made to work with 8086/8088 processors.it cannot fetch its instruction by own so its buses(address and data buses)are simply connected to the respective buses of the processor.its instruction are recognized by the word F because each and every instruction of this coprocessor starts with the word F.this is how the min processor distinguishes between its own and the coprocessor instructions.(eg):-FADD,FSUB,etc.this coprocessor has 8-registers eacch capable of storing 80-bit temporary real numbers. the BUSY pin of the coprocessor is connected to the main processor's TEST pin.this TEST pin is active low in nature.this is because the speed of operation of the coprocessor and the main processor is different. the need of this coprocessor is because the calculation speed of maths operations containing floating real numbers is very fast than the processors like 8086/8088.during the execution of the program if the processor encounters the instruction starting with F word(11011)then it simply gives control to the 8087.initially the coprocessor is initialized by loading it with the control word which gives the idea to the 8087 that which exceptions are to be ignored.usually after the calculations the status word of the coprocessor is loaded to see which errors hve occurred.
Which processor first integrated the math coprocessor in the CPU chip?
your mom!intel1883
What is an arithmetic series?
An arithmetic series is the sum of the terms in an arithmetic progression.
Is calcul arithmetic or calculus in English?
Arithmetic.
What are the applications of arithmetic algebra?
Sure. There are other applications of arithmetic, but algebra without arithmetic is impossible. A broad knowledge of arithmetic is essential for mastery of algebra.
