Extended Algorithm Extended algorithms (algorithms contained in the alg.ext file) are used by
Data I/O to handle device approvals and special device algorithm
updates.
False Positive In programming, a misprogrammed fuse that retains minimal
operational characteristics so that it passes the fuse test. These may be
inadequately programmed, or over-programmed so that they will fail
later in circuit.
File Transfer Operations An operation involving the transfer of data between the programmer and
a host. Upload and download are file transfer operations.
Filename The name of the disk file to use during file operations. The filename must
follow standard DOS conventions: up to eight alphanumeric characters,
followed by an optional three-character file extension, with the two fields
separated by a period. An example of valid filenames would be 27256.dat
or filename.c.
Fuse Verification A type of post-programming device check that checks the fuse pattern
programmed into a logic device with the pattern in user memory.
Fusemap The fuse-level description portion of a programmable integrated circuit.
Fusemaps are typically files in JEDEC Standard # 3A and are downloaded
to PLD programmers for device implementation.
Handshaking The required sequence of signals for communication between two units.
The I/O bus protocol for a unit defines its handshaking requirements.
This is especially true for asynchronous I/O systems in which each signal
requires a response to complete an I/O operation.
High-speed Download A special feature of the programmer that allows the programmer to
download data from a PC at 115.2K baud. To take advantage of this
feature, you must be using HiTerm on a PC, you must enable the High
Speed Download parameter, and you must send User Menu Data to the
Remote port.
High-speed Logic Drivers A device test that increases the speed of the logic transitions between 0 to
1 and 1 to 0 of the test vector input states. This test is a diagnostic tool
designed to help debug and classify test vector failures. Specifically, this
test is designed to help identify vector transitions that are speed
dependent.
Host A micro, mini, or mainframe computer used to control the programmer
in Remote mode. You must use a software driver, such as Data I/O’s
PROMlink to allow the computer to communicate with the programmer.
Host Command (download
& upload)
The command that is sent from the programmer to the host system
during uploading/downloading. See Download Host Command and
Upload Host Command.
I/O Address Offset This value influences the beginning address where data is stored during a
file transfer operation. For uploads, the I/O Offset represents the address
to start loading a formatted data file. For downloads, the I/O Offset is
subtracted from the beginning address in the formatted data file. The
result is then added to the memory begin address to determine where the
block of data is loaded.
