ADDRESS STROBE Meaning and
Definition
-
Address Strobe, commonly abbreviated as AS, is a signal used in digital electronics and computer systems to initiate or latch the address data on the address bus. It is a control signal that coordinates the timing and flow of information between the computer's memory and other connected devices, such as peripherals or input/output devices.
The Address Strobe signal is primarily generated by the CPU or memory controller to indicate that a memory or input/output operation is about to occur. When the AS signal is activated, it synchronizes with other control signals and assists in initiating the transfer of data over the address bus. The AS signal typically works in conjunction with other control signals, such as the Read (RD) and Write (WR) signals, to facilitate the proper transfer of information.
In operation, the Address Strobe signal is typically sent as a pulse or a series of pulses with a specific timing and duration. These pulses are used to latch or capture the address data on the address bus, allowing the memory or peripheral device to identify the desired location for data transfer. Once the address is latched, the data transfer can proceed, enabling the transfer of data to or from the addressed location in the computer's memory or external devices.
Overall, the Address Strobe signal plays a crucial role in coordinating the flow of data in digital systems, ensuring precise timing and coordination between memory and peripherals for efficient and accurate data transfers.
Etymology of ADDRESS STROBE
The term "Address Strobe" is derived from two separate words: "address" and "strobe".
1. Address: In computing, an address refers to a unique identifier that enables the location of a specific memory location or data storage location. It helps in accessing and retrieving information from a particular area in the computer's memory hierarchy.
2. Strobe: In electronics and digital systems, a strobe refers to a pulse or signal that acts as a timing reference for coordinating different parts of a circuit or system. It helps in synchronizing operations and ensuring proper timing for data transfer or other processes.
Therefore, when combined, "Address Strobe" signifies a signal or pulse that enables the timing and synchronization required for accessing and retrieving information from a specific memory address in a computer system. It is commonly used in computer memory systems to control the transfer and retrieval of data.
