72831L25PFI application field and working principle

72831L25PFI is an integrated high-speed first-in-first-out memory block that implements a dual-channel, single-ported memory structure. It is used in high-speed data buffering and transfers, as well as in space-constrained applications. The 72831L25PFI provides a maximum data transfer rate of 4 Gigabits per second (Gbps).

Application field

The 72831L25PFI is a versatile logic-FIFO (first-in, first-out) memory with a wide range of applications. It is typically used for data buffering in networking systems, such as packet aggregation and packet switching in routers and switches. It can also be used for buffering of video data transmission in optical communication systems, and for buffering of audio, image and video streams in multimedia systems. In addition, 72831L25PFI is used for data buffering in high-speed memory systems in network storage and storage area network (SAN) systems. It is also used in industrial automation, radar, automotive and aerospace applications that require high-speed data buffering.

Working Principle

The 72831L25PFI is a single-ported logic-FIFO memory block with two channels. The two channels are configured such that for each channel, there are two pointers that maintain the head and tail positions, and a number of entries that store the data. The block operates at a maximum of 4 Gbps and can hold up to 256 entries in each channel, with an entry size of 36-bits each. When the block receives a data signal from the input interface, it stores the data in a specific address location, as specified by the write pointer. At the same time, the write pointer is incremented, and the data is stored in consecutive memory locations. The read pointer is also incremented, so that the same data can be accessed from the same address if the data is to be read multiple times. When the read pointer and the write pointer are the same, the FIFO is said to be full.

The 72831L25PFI implements a single-ported signaling scheme to ensure read and write operations are synchronized. For any read or write operation, the current memory address is calculated by reading the read/write pointer, and then incrementing the pointer by the number of entries to be read/written. All operations such as write, read and re-read are synchronized via the single-ported signaling scheme, which ensures that the data in the memory can be accessed without any delays or overwriting. The single-ported signals also enable the FIFO to provide higher throughput and higher data transfer rates.

The 72831L25PFI is an advanced logic FIFO memory block designed to address the demands of high-speed data buffering and transfers. It is an ideal choice for applications that require high speed data transmissions, as it offers a maximum transfer rate of up to 4 Gbps, as well as an expandable memory capacity of up to 256 entries in each channel. Its single-ported signaling enables faster read and write operations, while preventing any data loss or corruption due to overwriting. Its small size and low power consumption make it ideal for space-constrained applications.
