What is microprogram sequencing?
Microprogram sequencing is the process of determining the order in which microinstructions are executed in a microprogram. This sequence is typically controlled by a counter or a control unit that fetches and executes microinstructions sequentially. It plays a crucial role in defining the operation of a microprogrammed control unit in a computer system.
What are the advantages of hardwired control design and microprogrammed control design?
fast
What are the different types of control units and explain the hardwired control unit with diagram?
Answer: Control unit is a computerized part of the speech processor. Most of the controls, such as program, volume and sensitivity, are located on the control unit.
What is the purpose of interposing relay panel?
Interposing relay panel is an Instrument / Electrical cabinet used for hardwired signal (digital inputs and outputs) interfaces between Instrumentation and Control Equipments system and associated circuit breakers,or other electrical devices for monitoring, controlling
What is the work associated with vegetation control?
Pest and plant control are some of the work that is associated with the vegetation control.
Historically which empire was most associated with having control of the Baltic states?
The Soviet Empire was associated with having control of the Baltic states.
How is quality control associated with a products dimensions?
How is quality associated with a product's dimensions.
What type of equipment is manufactured by DSC?
DSC manufactures card, secuirty, and fire access equipment. They also manufacture hardwired and addressable control panels, alarm devices, and central station receivers.
What actions is NOT associated with a revision control system?

What are the differences between hardwired control design and microprogrammed control design?
A hardwired control unit has a processor that generates signals or instructions to be implemented in correct sequence. This was the older method of control that works through the use of distinct components, drums, a sequential circuit design, or flip chips. It is implemented using logic gates & flip flops. It is faster, less flexible & limited in complexity A micro programmed control unit on the other hand makes use of a micro sequencer from which instruction bits are decoded to be implemented. It acts as the device supervisor that controls the rest of the subsystems including arithmetic and logic units, registers, instruction registers, off-chip input/output, and buses. It is slower, more flexible & greater complexity
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.
