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 ]
It was introduced by National Semiconductor, which has been sold to Texas Instruments. National Semiconductor claimed that this UART could run at up to 1.5 Mbit/s. 16C552 16750: 64-byte buffers. This UART can handle a maximum standard serial port speed of 460.8 kbit/s if the maximum interrupt latency is 1 millisecond. This UART was introduced ...
YMODEM is a file transfer protocol used between microcomputers connected together using modems. It was primarily used to transfer files to and from bulletin board systems. YMODEM was developed by Chuck Forsberg as an expansion of XMODEM and was first implemented in his CP/M YAM program.
Complete protocol flexibility for the bits transferred Not limited to 8-bit symbols; Arbitrary choice of message size, content, and purpose; Simple hardware and interfacing Hardware implementation for subs only requires a selectable shift register Subs use the main's clock and hence do not need precision oscillators
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 ...

The original Verilog simulator, Gateway Design's Verilog-XL was the first (and only, for a time) Verilog simulator to be qualified for ASIC (validation) sign-off. After its acquisition by Cadence Design Systems, Verilog-XL changed very little over the years, retaining an interpreted language engine, and freezing language-support at Verilog-1995.
No matter how you slice it, the Chicago Cubs were one of the most disappointing teams of 2024. Improved play in the second half enabled a winning record and a second-place finish in the NL Central ...
