From the instruction set perspective,
Intel processors
have eight general purpose registers in 32-bit mode, and sixteen general purpose registers in 64-bit mode, however, from the internal hardware perspective, Intel processors have many more registers.
Which processor requires more number of registers Mcq?
Which processor requires more number of registers? Explanation:
RISC
Requires more number of registers.
Which architecture has more number of registers?
The main distinguishing feature of
RISC architecture
is that the instruction set is optimized with a large number of registers and a highly regular instruction pipeline, allowing a low number of clock cycles per instruction (CPI).
Does CISC have more registers?
CISC RISC | Transistors used for storing complex instructions Spends more transistors on memory registers |
---|
Which processor includes multiple clocks?
CISC stands for Complex Instruction Set Computer. 2.
CSIC processor
has complex instructions that take up multiple clocks for execution. The average clock cycle per instruction (CPI) is in the range of 2 and 15.
What is not a CISC processor?
Explanation: The semantic gap is the gap between the high level language and the low level language. 7. Out of the following which is not a CISC machine. … Explanation: The
RISC machine architecture
was the first to implement pipe-lining.
Is an example of RISC processor?
Examples of processors with the RISC architecture include
MIPS, PowerPC, Atmel’s AVR, the Microchip PIC processors, Arm processors
, RISC-V, and all modern microprocessors have at least some elements of RISC. … The MIPS architecture was one of the first RISC ISAs and has been used widely to teach the RISC architecture.
Is CISC faster than RISC?
In common CISC chips are
relatively slow
(compared to RISC chips) per instruction, but use little (less than RISC) instructions. … Therefore fewer, simpler and faster instructions would be better, than the large, complex and slower CISC instructions.
How many registers does an i7 have?
There are
16
general purpose registers in the x86-64 architecture.
Why do computers need RAM registers?
Registers are a type of computer memory used to quickly accept, store, and transfer data and instructions that are being used immediately by the CPU. … The computer needs processor
registers for manipulating data and a register for holding a memory address
.
Why does Intel still use CISC?
The reason Intel uses a set of RISC-like micro-instructions internally is
because they can be processed more efficiently
. So a x86 CPU works by having a pretty heavy-duty decoder in the frontend, which accepts x86 instructions, and converts them to an optimized internal format, which the backend can process.
Why is x86 so popular?
The
IBM
train
It’s hard to shake 36 years of momentum, and that’s the main reason x86 is so popular. IBM is no longer a dominant force in computing, but up until the late 1980s, it dominated that industry. … Within a couple of years, several companies sold IBM-compatible computers.
Is MIPS a CISC processor?
The MIPS processor, designed in 1984 by researchers at Stanford University, is a
RISC (Reduced Instruction Set Computer) processor
. Compared with their CISC (Complex Instruction Set Computer) counterparts (such as the Intel Pentium processors), RISC processors typically support fewer and much simpler instructions.
What is an 8 core processor?
A quad-core CPU has four central processing units, an
octa-core CPU
has eight central processing units, and so on. This helps dramatically improve performance while keeping the physical CPU unit small so it fits in a single socket.
What is unique about a multi core processor?
Multicore processing
can increase performance by running multiple applications concurrently
. The decreased distance between cores on an integrated chip enables shorter resource access latency and higher cache speeds when compared to using separate processors or computers.
Which is the fastest memory?
- Fastest memory is cache memory.
- Registers are temporary memory units that store data and are located in the processor, instead of in RAM, so data can be accessed and stored faster.
