RISC architecture - computer architecture:
What is reduced regarding it? The answer of this question is that to make all instructions the equal length the number of bits that are used for the opcode is reduced. Accordingly fewer instructions are provided. The instructions that were thrown out are the less significant string and BCD (binary-coded decimal) operations. Acutely, now that memory access is limited there aren't various kinds of MOV instructions or ADD instructions. Therefore the previous architecture is called CISC (Complete Instruction Set Computer). RISC architectures are also known as LOAD/STORE architectures.
The number of registers in RISC is typically 32 or more. The first the MIPS 2000 and RISC CPU has 32 GPRs as different to 16 in the 68xxx architecture and 8 in the 80x86 architecture. The only disadvantage of RISC is the code size of it. Typically more instructions are required and there is a waste in short instructions (POP, PUSH).
Conversion of Decimal number 82.67 to its Binary Equivalent Ans. Firstly see the integer part 82 and determine its binary equivalent as The Binary equivalent is (101001
Description Variables show values that can be changed within a procedure or function. Local scope variables are placeholders that reside within a function- or a script-body.
Q. Explain about Butterfly permutation? Butterfly permutation: This kind of permutation is attained by interchanging the most significant bit in address with least significant
Which approaches do not require knowledge of the system state? Ans. Deadlock detection, deadlock prevention and deadlock avoidance; none of the given require knowledge of the s
Q. Register-to-register operands in RISC? Register-to-register operands: In RISC machines operation which access memories are LOAD and STORE. All other operands are kept in reg
State about the Logic Micro-operations These operations are performed on binary data stored in register. For a logic micro-operation each bit of a register is treated as a diff
Describe the Assume - Assembler directives ASSUME: This directive would be used to map the segment register names with memory addresses. Syntax is as below: ASSUME SS:
pls give the list of adaptive mechanism in artificial immune system
Minimise the logic function F (A, B, C, D) = Π M (1, 2, 3, 8, 9, 10, 11,14) ⋅ d (7, 15) Use Karnaugh map. Ans. Given function F=∏M(1,2,3,8,9,10,11,14).d(7, 15) F'=B'D+B'C+AC+AB'
In binary counter the flip flop of lowest order position is complemented with each pulse. This means that JK input position must be maintained with logic one
