Aircraft Communications Addressing And Reporting System - ARINC Specifications
429 Specification for receiving and broadcasting ARINC 429 broadcast data (data transfer between avionics LRUs) ... ARINC 429 is the one way communication data bus (one pair of data bus use for transmit data and another pair of data bus use for receive data) ARINC 618 Defines the air / ground. 619 Defines the protocols for the ACARS / CMU to use to transfer file data between other avionics in the aircraft ...
... Originally simply known as SDRAM, single data rate SDRAM can accept one command and transfer one word of data per clock cycle ... Chips are made with a variety of data bus sizes (most commonly 4, 8 or 16 bits), but chips are generally assembled into 168-pin DIMMs that read or write 64 (non-ECC) or 72 (ECC) bits at a time ... Use of the data bus is intricate and thus requires a complex DRAM controller circuit ...
... DDR2 SDRAM is a double data rate synchronous dynamic random-access memory interface ... In addition to double pumping the data bus as in DDR SDRAM (transferring data on the rising and falling edges of the bus clock signal), DDR2 allows higher bus speed and requires lower power by ... combine to require a total of four data transfers per internal clock cycle ...
Bus Encryption
... Bus encryption is the use of encrypted program instructions on a data bus in a computer that includes a secure cryptoprocessor for executing the encrypted instructions ... Bus encryption is used primarily in electronic systems that require high security, such as Automated teller machines, TV set-top boxes, and secure data communication devices such as digital police radios ... Bus encryption can also mean encrypted data transmission on a data bus from one processor to another processor ...
SIGBUS - Bus Error
... On POSIX-compliant platforms, bus errors usually result in the SIGBUS signal being sent to the process that caused the error ... A bus error rarely means that the computer hardware is physically broken—it is normally caused by a bug in a program's source code ... There are two main causes of bus errors Non-existent address The CPU is instructed by software to read or write a specific physical memory address ...

Famous quotes containing the words bus and/or data:

    If Rosa Parks had taken a poll before she sat down in that bus in Montgomery, she’d still be standing.
    Mary Frances Berry (b. 1938)

    To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.
    F. Scott Fitzgerald (1896–1940)
