How do you make bus port connectors in Logic Works?
Press Ctrl+B (or alternative go to "Schematic" --> " New Breakout") Enter the Bus name followed by the number of pins you want and press OK. example for name is D0..2 -> creates Bus D with signals D0, D1 , D2
What is ALE in 8085 in microprocessor?
ALE=Address Latch Enabled.(pin number 30 in 8085)8085 has a special pin referred as ALE, which indicates whether multiplex bus functions as an address bus or a data bus. Whenever 8085 starts any new operation, ALE signal goes to logic 1 for about 1/2 clock cycle, at about the falling edge of CLK. If ALE=1 then multiplex bus functions as address bus. After that half clock cycle, it goes to logic 0 for nearly 3 or 4 clock cycles. If ALE=0 then multiplex bus acts as a data bus.The ALE pin helps to enable the latching of lower order ADDR bus. The AD0-AD7 pins, as well as other control pins such as S0, S1, IO/M-, and the other address pins A8-A15, are setup to be correct at the falling edge of ALE.
What is business logic and presentation logic in java?
business logic ....refers to the domain specific logic rules,proc,and processes presentation logic......concerned with how objects are displayed to the user of the software
How is c language different from fuzzy logic?
fuzzy logic is a logic which we have to implement in c language
What are the applications of tristate logic?
The most common application of tri-state logic is in the use of LED circuits. They can also be used on a shared electric bus.
What is the difference between external data bus and internal data bus?
A data bus connects different parts of a circuit and comprises a group of parallel wires, each one carrying a different logic signal.
Difference between synchronous bus and asynchronous bus?
1. Syncrhonous bus includes clock in control lines whereas asynchronous bus is not clocked. 2. the devices which need to be connected by synchronous bus should be at same speed whereas an asynchronous bus may connect many devices with varying speeds. 3. A fixed protocol is defined to communicate using synchronous bus which is relative to the clock. An asynchronous bus uses handshaking protocol.
What do you mean by data bus buffer?
It simply amplifies the current or power. It is used to increase the driving capability of a logic socket.

Diff by the way unidirectional buffer and bidirectional buffer?
A bi-directional buffer includes first and second unidirectional buffers connected for retransmitting signals in opposite directions between first and second buses. When an external bus driver pulls the first bus low, the first unidirectional buffer pulls the second bus low and generates a signal inhibiting the second unidirectional buffer from actively driving the first bus. When the external bus driver allows the first bus to return to the high logic level, the first unidirectional buffer temporarily supplies a high charging current to the second bus to quickly pull it up. Similarly, when an external bus driver pulls the second bus low, the second unidirectional buffer pulls the first bus low and generates a signal inhibiting the first unidirectional buffer from actively driving the second bus. When the external bus driver allows the second bus to return to the high logic level, the second buffer temporarily supplies a high charging current to the first bus to quickly pull it up. The bi-directional buffer includes a register for storing and reading out data representing successive logic states of a signal on the first bus, thereby providing a history of data appearing on the bus
What is the LSI Logic about in computers?
The LSI Logic in computers refers to the host bus adapter that provides throughput to internal server storage rays in computers. It is available for purchase through several different websites such as Amazon and Yahoo!
Why higher order address bus not multiplexed with data bus of 8085?
The higher order address bus is not multiplexed with data bus of 8085 because that is the way Intel designed the processor. Besides, the data bus is only 8 bits and the address bus is 16 bits. If you were to multiplex the whole address bus on the data bus, you would need two T1 (ALE) states, and that would be excess logic. Back to the original answer - that is simply the way Intel designed the processor.
What is a bus specify the function of address bus and direction of information flow on the address bus?
A bus is a collection of conducting wires which connect the processor and other devices in parallel scheme. The function of an address bus is to carry the address of the memory locations from the processor to the memory device, the address bus is unidirectional(only in one direction) in this processor so the flow of information on this bus is from the microprocessor to the attached device(memory module).
What is the difference between unidirectional buffer and bidirectional buffer?
Unidirectional buffer allows data to flow in only one direction, either from input to output or from output to input. Bidirectional buffer allows data to flow in both directions, enabling communication between two devices or systems bidirectionally.

What is meant by multiplexed address data bus?
Multiplexing of the data and address buses is done to reduce the pin count on the microprocessor chip. The address information is emitted at the beginning of a memory cycle, and external logic is expected to latch that address. Then the bus becomes the data bus and the required data is transferred to or from memory using the latched address.In the 8085, this saves 8 pins at the cost of 1 pin, ALE. In the 8086/8088, this saves 16 pins at the cost of 1 pin, ALE. In some architectures or modes, there is no ALE, but the external logic is still required to know when to latch the address based on some other criteria.As an example of that, in the original Intel 4004, the microprocessor's bus was 4 bits, while the address bus was 12 bits. There were 8 clock cycles. In the first three, external logic was expected to latch the three 4 bit parts of the 12 bit address. Similarly, in the next two, the resultant opcode, which as 8 bits, was multiplexed by the external logic into two 4 bit parts. (The 4004 was only a 16 pin chip, but it packed a lot of complexity in its day, being the world's first microprocessor.)
