Early versions have a broken FIFO buffer and therefore cannot safely run any faster than the 16450 UART. [14] Versions of this UART that were not broken have 32-character FIFO buffers and could function at standard serial port speeds up to 230.4 kbit/s if the operating system has a 1 millisecond interrupt latency.
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 ]
The USART's synchronous capabilities were primarily intended to support synchronous protocols like IBM's synchronous transmit-receive (STR), binary synchronous communications (BSC), synchronous data link control (SDLC), and the ISO-standard high-level data link control (HDLC) synchronous link-layer protocols, which were used with synchronous voice-frequency modems.
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.
This ambiguity is intentional. Wishbone is made to let designers combine several designs written in Verilog, VHDL or some other logic-description language for electronic design automation (EDA). Wishbone provides a standard way for designers to combine these hardware logic designs (called "cores"). Wishbone is defined to have 8, 16, 32, and 64 ...

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.
