Verilog-to-Routing (VTR) is an open source CAD flow for FPGA devices. [1] [2] [3] VTR's main purpose is to map a given circuit described in Verilog, a hardware description language, on a given FPGA architecture for research and development purposes; the FPGA architecture targeted could be a novel architecture that a researcher wishes to explore, or it could be an existing commercial FPGA whose ...
Congress included $35 million in 2018 and $65 million in 2019 in the budget in support of this. In February 2019, VTR cleared Critical Decision 0, demonstrating a mission need requiring investment, the first in a series of project approvals. At that time, Secretary of Energy Rick Perry announced the start of the Versatile Test Reactor Project. [4]
The system is branded as VideoPlus+/ShowView in Europe due to an existing trademark registration for "VCR" by Philips in that continent, and as G-Code (the "G" standing for the system's developer, Gemstar) in Japan because VCR is not a common abbreviation there ("VTR," for videotape recorder, is used instead). Japan initially used the name ...
The Combined Construction and Operating License (Regulatory Guide 1.206, COL) replaced the previous Draft Regulatory Guide 1145 as the licensing process for new nuclear power plants in the United States. It is a part of a newer "streamlined" process that encourages standard plant designs, and prevents delays in operation that contributed to the ...
The PV-100 was Sony's second model of 2-inch helical VTR, and was released in September 1962. The PV-100 was solid state and had a total weight of about 132 pounds (60 kg). It found use in the airline industry as a replacement for 8mm and 16mm film stock, which were used for in-flight entertainment.
Shortly after it came out, both the 1" Type B and 1" Type C formats of VTR came out. Both used less costly tape, and made just about as good of a picture. Ampex in 1961 made a 2 inch helical scan VTR for a short time, the VR-8000. They also produced another 2" helical VTR, the VR-660, in 1963.
When EIAJ-1 was standardized, no videocassette recorders had yet been introduced. One of the main drawbacks to the format was the need to carefully thread the end of the tape around the head drum, through a gap between the capstan and pinch roller, and around a variety of guides and tensioners.
AMPEX quadruplex VR-1000A, the first commercially released video tape recorder in the late 1950s; quadruplex open-reel tape is 2 inches wide The first portable VTR, the suitcase-sized 1967 AMPEX quadruplex VR-3000 1976 Hitachi portable VTR, for Sony 1" type C; the source and take-up reels are stacked for compactness. However, only one reel is ...
