What is timing and control in computer architecture?
Timing pulses are used in sequencing the micro-operations in an instruction. For example, when LDA instruction is executed, the memory is read operation is performed in timing pulse T1 and memory writer operation is performed in timing pulse T2. Now the combination of the signal LDA and T1 can be used as a control signal for performing read operation. Similarly, the combination of the signal LDA and T2 can be used as a control signal for performing write operation.A master clock generator is used for controlling the timing for all register in a computer system. A state of a register cannot be changed by a clock pulse until it is enabled by the control signal, which are generated in the control unit and provide control inputs for multiplexers, processor register, and micro-operations. The control organization is of two types; hardwired control and micro-programmed control.Hardwired ControlIn a hardwired control, the control signals are generated by using the collection of combinational circuits. The main advantage of the hardwired control is that, it can be optimized to produce a fast mode of operation. Whenever a change or modification is to be done in the design, then the wiring among the various components needs to be done. Micro-Programmed ControlIn a micro-programmed control, a control memory is used for storing control information which is also programmed for initiating the sequence of micro-operations. Whenever any change or modification is required in the design, it can be done by updating the micro-program in the control memory.
What are the problem associated with dynamic memory allocation?
Not freeing it when you no longer need the memory.
Memory and thinking are most closely associated with which part of the central nervous system?
Memory and thinking are most closely associated with the Frontal Cortex.
Why memory to memory acess is not possible in 8086 micro processor?
Memory to memory access is certainly possible in the 8086/8088 microprocessor. Look at the repeated string copy instructions.
Difference between Picture Box control and Image Control?
Image BoxPicture Box1) it is not act as container control 2) not use of memory to store the picture3) editing of picture is not possible in picture box4) Not having auto size property5) Having stretch property1) it act as container control2) use of memory to store the picture3) editing of picture is possible in picture box4) having auto size property5) not having stretch property
Can I upgrade my laptop notebook memory?
It depends on the type of laptop you have. It is possible to upgrade the memory on most notebooks. It's also possible to add external memory.
Automatic and effortful processing are associated with which stage of memory?
Automatic processing is associated with implicit memory, while effortful processing is associated with explicit memory. Automatic processing occurs without conscious awareness, while effortful processing requires conscious effort and attention.
What side of heart controls memory functions?
Medically heart does not control memory. Brain has the memory controls.
What is architecture characteristic of risc and cisc?
character of risc -load store architecture -fixed length instruction -hardwired control instruction -pipelined implementation character of cisc -many instruction that access memory directly -large number of addressing mode -variable length instruction code -support of misaligned accesses answer by sachita pandey
