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).
A device which converts BCD to Seven Segment is called ? Ans. DECODER is a device that converts BCD to Seven Segment. This coverts binary words in alphanumeric characters.
Using D-Flip flops and waveforms explain the working of a 4-bit SISO shift register. Ans. Serial In-Serail Out Shift Register: Fig.(a) demonstrates a 4 bit serial in-serial out
What is bus arbitration? It is method by which the next device to become the bus master is selected and bus mastership is transferred to it. There are two ways for doing this:
Compiler is used to change the high-level language program into machine code at a time. It doesn't needs special instruction to store in a memory, it keeps automatically. The imple
Extranets can be also used to connect an intranet to Internet so that remote offsite access can be made in a company's intranet by an authorized individual. This can facilitate thr
Explain the Benefits of Interpreter? The benefit of an interpreter though is that it doesn't need to go through the compilation stage during which machine instructions are gene
The Concept of Thread Thread is a chronological flow of control within a process. A process can include one or more threads. Threads have their own register values and program
