What is the source of the instruction from which all proteins are made?
Basic source of instruction for protein synthesis is DNA.
What is the different between MOV and MVI in 8085?
In the 8085 microprocessor, the MOV instruction copies data between two registers, or between a register and memory. The MVI instruction differs only in that the source data is contained in the byte immediately following the opcode byte.
What is 6 stage instruction pipelining?
1. FI (fetch instruction) - get the next instruction 2. DI (decode instruction) - decode the opcode and operands 3. CO (calculate operands) - calculate EA of the operands 4. FO (fetch operands) - fetch operands from memory (not necessary for register data) 5. EI (execute instruction) - execute instruction storing result if necessary 6. WO (write operand) - write the result in MEM
What is the use of the source index in a 8086 processor?
The Source Index (SI) register is used by certain string type instructions to read from memory. Typically, the instruction is "repeated" with a repeat prefix to iterate through memory until some condition is met.
What types of locations can hold source and destination operands?
Source and result operands can be in one of four areas:• Main or virtual memory: As with next instruction references, the main or virtual memory address must be supplied.• Processor register:With rare exceptions, a processor contains one or more registers that may be referenced by machine instructions. If only one register exists,reference to it may be implicit. If more than one register exists, then each register is assigned a unique name or number, and the instruction must contain the number of the desired register.• Immediate: The value of the operand is contained in a field in the instructionbeing executed.• I/O device: The instruction must specify the I/O module and device for the operation.If memory-mapped I/O is used, this is just another main or virtualmemory address.
What is your number 1 source for golf?
RotarySwing.com was the first online golf instruction website and is the number 1 source for golf instruction videos online.
How many register are located in 8088microprocessor?
there are 14 registers in 8088 micro processor. All the 14 are 16 bit registers. They are4 segment registers viz - code segment register, stack segment register, data segment register, extra segment register.general registers are - accumulator register i.e. AX, base register i.e. BX, count register i.e. CX, data register i.e. DX and stack pointer (SP), base pointer (BP).index registers are - source index(SI), destination index(DI),and the other registers are instruction pointer and flags register.
What are the five stages in DLX pipeline in computer architecturect?
DLX is a simple pipeline architecture for CPU. It is mostly used in universities as a model to study pipelining technique.The architecture of DLX was chosen based on observations about most frequently used primitives in programs. DLX provides a good architectural model for study, not only because of the recent popularity of this type of machine, but also because it is easy to understand.Like most recent load/store machines, DLX emphasizes A simple load/store instruction setDesign for pipelining efficiencyAn easily decoded instruction setEfficiency as a compiler targetOperations There are four classes of instructions: Load/StoreAny of the GPRs or FPRs may be loaded and stored except that loading R0 has no effect.ALU OperationsAll ALU instructions are register-register instructions.The operations are :- add- subtract- AND- OR- XOR- shiftsCompare instructions compare two registers (=,!=,,=).If the condition is true, these instructions place a 1 in the destination register, otherwise they place a 0.Branches/JumpsAll branches are conditional.The branch condition is specified by the instruction, which may test the register source for zero or nonzero.Floating-Point Operations- add- subtract- multiply- divideAn Implementation of DLXImplementing the instruction set requires the introduction of several temporary registers that are not part of the architecture.Every DLX instruction can be implemented in at most five clock cycles. The five clock cycles are Instruction fetch cycle (IF)Instruction decode/register fetch (ID)Execution/Effective address cycle (EX)Memory access/branch completion cycle (MEM)Write-back cycle (WB)Detailed description of each follows:Instruction fetch cycle (IF):IR
What learn about drama?
Drama is the part of literature,,It is the source of entertainment and instruction.
What is a memory register?
A memory mapped register is a register that has its specific address stored in a known memory location.
What are the typical elements of machine instruction?
Operation code, source operand reference, result operand reference, and next instruction reference. (source: Computer organization and architercture eighth edition by William Stallings)
