Logic - FIFOs Memory is a type of computer memory which is implemented in the form of an array that is accessed in a first-in, first-out (FIFO) fashion. An example of this type of memory is the SN74ACT7811-15FN which is used in a wide range of applications. This article will discuss the SN74ACT7811-15FN and its applications, as well as the working principle behind it.

Tutorial

The SN74ACT7811-15FN is a logic device that incorporates the logic of a First-In-First-Out (FIFO) register. It has 15-bits of buffer memory and an associated control logic using three control lines, denoted as PIPO, PIPE and PE. It is often used in applications where data needs to be buffered, or stored, in order to maintain the integrity of the data being transferred from one point to another.

Applications

The SN74ACT7811-15FN can be used in a number of different applications. It is often used for audio signal processing, serial port communications, and data acquisition. The chip offers a wide range of benefits in these applications. For instance, it can be used to reduce data loss and distortion in audio signals, enable more reliable communications between serial ports, and enable faster data acquisition. Furthermore, it can be used to implement various types of bus architectures and protocols, such as the SCSI bus.

Work Principle

The operation of the SN74ACT7811-15FN is based on the concept of a queue. The queue consists of two sets of registers, a set of input registers and a set of output registers. Data is entered into the input registers and then shifted to the output registers. The control logic associated with the chip then handles the read and write operations between the two sets of registers.

When data is entered into the input registers, the control logic checks to see if there is any available space. If there is space available, the data is shifted over and written to the output registers. If there is not enough space, the data is discarded and it becomes the responsibility of the software to handle the overflow situation.

When data is read from the output registers, the control logic ensures that the read operation only occurs when there is data available. If there is no data available, the read operation is simply ignored. This is done to ensure that data accuracy is maintained.

Overall, the SN74ACT7811-15FN is a great logic device for a wide range of applications. It offers a number of benefits in terms of data integrity and accuracy, as well as being able to handle large amounts of data in a very efficient manner. It has become a popular choice for many different types of applications where data needs to be buffered, or stored, and processed in a FIFO fashion.
