UART with 16-byte FIFO buffers. Up to 1.5 Mbit/s. The ST16C155X is not compatible with the industry standard 16550 and will not work with the standard serial port driver in Microsoft Windows. 16C2450: Dual UART with 1-byte FIFO buffers. 16C2550: Dual UART with 16-byte FIFO buffers. Pin-to-pin and functional compatible to 16C2450.
The 16550 UART (universal asynchronous receiver-transmitter) is an integrated circuit designed for implementing the interface for serial communications. The corrected -A version was released in 1987 by National Semiconductor . [ 1 ]
Representation of a FIFO queue. In computing and in systems theory, first in, first out (the first in is the first out), acronymized as FIFO, is a method for organizing the manipulation of a data structure (often, specifically a data buffer) where the oldest (first) entry, or "head" of the queue, is processed first.
Verilog's 'event' primitive allowed different blocks of procedural statements to trigger each other, but enforcing thread synchronization was up to the programmer's (clever) usage. SystemVerilog offers two primitives specifically for interthread synchronization: mailbox and semaphore. The mailbox is modeled as a FIFO message queue.
JTAG (named after the Joint Test Action Group which codified it) is an industry standard for verifying designs of and testing printed circuit boards after manufacture.. JTAG implements standards for on-chip instrumentation in electronic design automation (EDA) as a complementary tool to digital simulation. [1]

Tech reporter Kara Swisher is working towards assembling a group of investors to purchase The Washington Post from billionaire Jeff Bezos.
Verilog-2001 is a significant upgrade from Verilog-95. First, it adds explicit support for (2's complement) signed nets and variables. Previously, code authors had to perform signed operations using awkward bit-level manipulations (for example, the carry-out bit of a simple 8-bit addition required an explicit description of the Boolean algebra ...
