The average rate of cosmic-ray soft errors is inversely proportional to sunspot activity. That is, the average number of cosmic-ray soft errors decreases during the active portion of the sunspot cycle and increases during the quiet portion. This counter-intuitive result occurs for two reasons.
In 1979, James Ziegler of IBM, along with W. Lanford of Yale, first described the mechanism whereby a sea-level cosmic ray could cause a single-event upset in electronics. 1979 also saw the world's first heavy ion "single-event effects" test at a particle accelerator facility, conducted at Lawrence Berkeley National Laboratory's 88-Inch ...
Players control Ares' movement with WASD keys on the keyboard and aim with a mouse.Ares can double jump and roll to avoid attacks and obstacles and can change his suit during the course of the game which gives him a different aesthetic appearance and abilities.
One of the major improvements the PCI Local Bus had over other I/O architectures was its configuration mechanism. In addition to the normal memory-mapped and I/O port spaces, each device function on the bus has a configuration space, which is 256 bytes long, addressable by knowing the eight-bit PCI bus, five-bit device, and three-bit function numbers for the device (commonly referred to as the ...
Exclusive OR the byte in the D register with the memory byte at R(X), move the result into the D register: XOR: 2 F4: Add the byte in the D register to the memory byte at R(X), move the result into the D register: 2 F5: Subtract the byte in the D register from the memory byte at R(X), move the result into the D register: SD: 2 F6: Shift the D ...
The Aerial Reconfigurable Embedded System (ARES) was a concept for an unmanned VTOL flight module that can transport various payloads. The concept started as the TX ( Transformer ) in 2009 for a terrain-independent transportation system centered on a ground vehicle that could be configured into a VTOL air vehicle and carry four troops.
The System Management Bus (SMBus or SMB) is a single-ended simple two-wire bus for the purpose of lightweight communication. Most commonly it is found in chipsets of computer motherboards for communication with the power source for ON/OFF instructions.
STM8 instructions consist of an optional prefix byte (72 16, 90 16, 91 16, or 92 16), an opcode byte, and a few (up to four, but rarely more than two) bytes of operands. Prefix bytes mostly modify the addressing mode used to specify the memory operand, but in some cases, prefixes 72 and 90 change the meaning of the opcode byte completely.
