What is the role of strobe?

In computer or memory technology, a strobe is a signal that is sent that validates data or other signals on adjacent parallel lines. In memory technology, the CAS (column address strobe) and RAS ( row address strobe ) signals are used to tell a dynamic RAM that an address is a column or row address.

What is strobe in logic circuit?

Electronic logic circuits often accept data from one or more inputs, but are required to recognize and process this data at a particular time when it is valid. A strobe line is employed to signal the receiving circuit when the input data is valid.

What is strobe control?

The strobe control technique of asynchronous data transfer operates a single control line to time each transfer. The strobe can be activated by either the source or the destination unit. The strobe is a single line that instructs the destination unit when an accurate data word is accessible in the bus.

What is nibble multiplexer?

In computers and digital technology, a nibble (pronounced NIHB-uhl; sometimes spelled nybble) is four binary digits or half of an eight-bit byte. Nibble interleaving or multiplexing takes a quadbit or nibble from a lower-speed channel as input for a multiplexed signal on a higher-speed channel.

What is strobe and handshaking explain in detail?

Handshaking usually uses two additional hardware lines, one is called “strobe” and the other is called “acknowledge”. The sender provides the signal to the strobe line and the receiver provides the signal to the acknowledge line. Handshaking can be used in both parallel data transfer and serial data transfer.

What is a strobe in FPGA?

Data strobe is the clock signal for the data lines. Each data byte has their own strobe. It is bidirectional signal. It is transmitted by the same component as the data signals.

What are the advantages of handshaking over strobe control?

2.) The second control signal is used to acknowledge that data has been received. The handshake can either be initiated by a source or a destination. Strobe uses a single control line signal to time each transfer whereas handshake uses two control signals.

What is selection lines in multiplexer?

select lines, which are used to select which input line to send to the output. A multiplexer makes it possible for several input signals to share one device or resource, for example, one analog-to-digital converter or one communications transmission medium, instead of having one device per input signal.
