What is RISC microprocessor?
RISC, or Reduced Instruction Set Computer.
is a type of microprocessor architecture that utilizes a small, highly-optimized set of instructions, rather than a more specialized set of instructions often found in other types of architectures.
What is RISC vs CISC?
The CISC approach attempts to minimize the number of instructions per program, sacrificing the number of cycles per instruction. RISC does the opposite, reducing the cycles per instruction at the cost of the number of instructions per program.
Why is RISC faster than CISC?
RISC processors can be designed more quickly than CISC processors due to its simple architecture. The execution of instructions in RISC processors is high due to the use of many registers for holding and passing the instructions as compared to CISC processors.
Which came first RISC or CISC?
Microprocessors were introduced in the 1970s, the first commercial one coming from Intel Corporation. By the early 1980s, the RISC architecture had been introduced. The RISC design came about as a total redesign because the CISC architecture was becoming more complex.
Which are the processors based on RISC Mcq?
This set of Embedded Systems Multiple Choice Questions & Answers (MCQs) focuses on “RISC Processor”. 1. Which are the processors based on RISC? Explanation: SPARC and MIPS processors are the first generation processors of RISC architecture.
Where are RISC processors used?
RISC (Reduced Instruction Set Computer) is used in portable devices due to its power efficiency. For Example, Apple iPod and Nintendo DS. RISC is a type of microprocessor architecture that uses highly-optimized set of instructions.

Who coined the term RISC?
One was a project at the University of California, Berkeley, under the direction of David Patterson and Carlo H. Sequin—who coined the term “RISC.” The other project was led by John L. Hennessy at Stanford University.
Is Pentium RISC or CISC?
Intel Pentium processors are mainly CISC-based, with some RISC facilities built into them, whereas the PowerPC processors are completely RISC-based.
