PAL (redirected from palling around)

PAL

(1) (Programmable Array Logic) A type of programmable logic chip (PLD) that contains arrays of programmable AND gates and predefined OR gates. PALs are defined by their number of inputs and outputs; for example, a 22v10 PAL means 22 inputs and 10 outputs. The inputs are connected by fuses to logic circuits, which themselves are connected by fuses to the output lines. Often used for glue logic, the fuses are blown apart by a programmer device to create the custom configuration. See PLD and glue logic.

(2) (Phase Alternating Line) A color TV standard that was developed in Germany. It broadcasts 25 interlaced frames per second (50 half frames per second) at 625 lines of resolution. Brazil uses PAL M, which broadcasts 30 fps. PAL is used throughout Europe and China as well as in various African, South American and Middle Eastern countries. PAL's color signals are maintained automatically, and the TV set does not have a user-adjustable hue control. See NTSC and SECAM.

(3) (Paradox Application Language) A programming language used within Borland's Paradox relational database. Paradox is part of Corel's WordPerfect suite. See WordPerfect Office.
