Abstract: A decoder that includes a micro-alias register to store information from a micro-operation for use by later micro-operations in the micro-operation flow. The decoder includes one or more XLAT PLAs that produces PLA control micro-operations ("Cuops"), a microcode sequencing unit that produces microcode Cuops, and an aliasing mechanism that extracts fields and stores them in macro-alias registers. A multiplexer is provided to select the appropriate Cuop to be stored in a Cuop register. Multiple Cuops may issue each cycle. A multiplexer is coupled to select one of the Cuops and to store predetermined fields in the micro-alias register for use by subsequent Cuops. Micro-alias data and macro-alias data can be utilized simultaneously with a Cuop to form an Auop.

Abstract: A livestock detaining gate preferably constructed of steel, having a gate latch system for locking gate panels into a closed position, and for permitting the panels to rotate into either a forward or rear open position. The latch system is preferably comprised of two cylindrical pipe sections suspended from parallel bars, which are also parallel to the upper edge of the closed gate panels, and are positioned slightly above said upper edge, with one cylinder to the front and one to the rear of the closed gate panels. An additional parallel rod is positioned slightly ahead of the forward cylinder, with another parallel rod positioned slightly behind the rear cylinder. The cylinder may swing inward upon contact with the closing gate panel top, allowing the gate panel to close. However, the extreme forward and rear rods prevent either cylinder from swinging outward, thus locking the gate panels in the closed position. A cantilever lift system is connected to the cylinder supporting rods.
