The layer of an INtime application that loads programs into memory for execution,
such as when a user enters a command at the console.
Events that occur at random times.
(Basic I/O System) On a PC system, the code that resides in ROM to supply
OS-independent access to the computer’s I/O system.
(Blue Screen of Death) An acronym used to describe total Windows failure.
On a network, a client is a computer which makes requests of a remote system that
acts as a server. For example, a client could request a remote server to supply it with
data from one of the server’s disk files.
An 8-byte data structure taken from a descriptor table in memory. Descriptors provide
the CPU with the data it needs to map a logical address into a linear address. The
fields of a descriptor include information concerning segment size, base address,
access rights, and segment type (such as read/write segment, executable segment, call
gate, task gate, trap gate, etc).
Predictable response time. Enables threads to execute before their deadlines expire.
The hardware interface between the CPU or system bus and a device unit.
The software interface between the I/O system and a device controller.
A configuration of INtime where an INtime kernel (RT client) runs on a CPU that does
not run Windows.
A characteristic of object-based systems. The representation of an object is hidden
from the user of that object. Only the object’s type manager can manipulate an object.
Users of an object can manipulate the object only by invoking type manager functions
for the object.
(End of Interrupt) A command sent to a PIC to indicate that an interrupt handler
completed processing an interrupt.
Applications can respond to interrupts as they occur; they do not waste time polling
for interrupts.
A program that receives control when either the operating system or hardware detects
an error.
Generic name for object types managed by INtime software that allow threads to
synchronize and communicate with each other. Exchange objects include:
semaphores, mailboxes, and regions.
