SPARC has RISC architecture which has a simple instruction set but MC68020, MC68030, and 8086 have CISC architecture which is more complex than CISC.
62. Which is the first company that defined RISC architecture?
A. Intel
B. IBM
C. Motorola
D. MIPS
Answer: B
In the 1970s IBM identified RISC architecture. RISC architecture is used in high-end applications such as video processing, telecommunications, and image processing.
63. Which of the following processors execute its instruction in a single cycle?
A. 8086
B. 8088
C. 8087
D. MIPS R2000
Answer: D
MIPS R2000 possesses RISC architecture in which the processor executes its instruction in a single clock cycle and also synthesizes complex operations from the same reduced instruction set.
64. How is memory accessed in RISC architecture?
A. load and store instruction
B. opcode instruction
C. memory instruction
D. bus instruction
Answer: A
The data of the memory address is loaded into a register and manipulated, and its contents are written out to the main memory.
65. Which of the following has Harvard architecture?
A. EDSAC
B. SSEM
C. PIC
D. CSIRAC
Answer: C
PIC follows Harvard architecture in which the external bus architecture consists of separate buses for instruction and data whereas SSEM, EDSAC, and CSIRAC are stored-program architecture.
66. Which of the following statements are true for von Neumann architecture?
A. shared bus between the program memory and data memory
B. separate bus between the program memory and data memory
C. external bus for program memory and data memory
D. external bus for data memory only
Answer: A
von Neumann architecture shares a bus between program memory and data memory whereas Harvard architecture has a separate bus for program memory and data memory.
67. What is CAM stands for?
A. content-addressable memory
B. complex addressable memory
C. computing addressable memory
D. concurrently addressable memory
Answer: A
(CAM) stands for Content-addressable memory is computer memory that operates as a hardware search engine for search-intensive applications.
CAM is capable of searching its entire contents in a single clock cycle. Non-von Neumann architecture is based on content-addressable memory.
68. Which of the following processors uses Harvard architecture?
A. TEXAS TMS320
B. 80386
C. 80286
D. 8086
Answer: A
TEXAS TMS320 processors use Harvard architecture. It is a digital signal processor which has small and highly optimized audio or video processing signals. It possesses multiple parallel data buses.
69. Which company further developed the study of RISC architecture?
A. Intel
B. Motorola
C. university of Berkeley
D. MIPS
Answer: C
The University of Berkeley and Stanford university provides the basic architecture model of RISC.
70. Princeton architecture is also known as
A. von Neumann architecture
B. Harvard
C. RISC
D. CISC
Answer: A
The von Neumann architecture is also known as the von Neumann model or Princeton architecture.
