Technical Terms - Hardware (A-Z) - FPU

What does FPU stand for?

• Floating Point Unit

• Fast Processing Unit

• Fixed Point Unit

• Function Processing Unit

Where is the FPU located in a computer?

• Inside the CPU

• Separate from the CPU

• In the RAM

• In the GPU

What type of calculations does an FPU perform?

• Floating point calculations

• Integer calculations

• Boolean calculations

• String calculations

Why is it inefficient to use the same processor for both integer and floating point operations?

• It slows down the processor

• It increases power consumption

• Different logic is required for each type of operation

• It reduces memory usage

What type of calculation would be sent to the FPU for processing: 1.0023 x 5.789?

• String calculation

• Floating point calculation

• Integer calculation

• Boolean calculation

What is typically used to measure FPU calculation speed?

• RPM

• FLOPS

• MBps

• IPS

What is the label for integer performance in SPEC benchmarks?

• FPUbench

• INTbench

• SPECfloat

• SPECint

What type of operation can be performed by both the integer processing unit and the FPU?

• Bitwise AND

• Addition

• String Concatenation

• Matrix Multiplication

What is the purpose of an FPU in a processor?

• To reduce power consumption

• To increase memory usage

• To improve graphics performance

• To handle calculations with non-integer numbers faster

Why is it usually unnecessary for a programmer to write instructions specifically for either processing unit?

• It slows down the processing speed

• It increases the complexity of the program

• It requires specialized programming skills

• The CPU automatically sends instructions to the corresponding processor
