<p>A digital processor is disclosed which is adapted for use in the guidance and stabilization of a guided missile. The digital processor is adapted to store a predetermined macroprogram and to process signals produced by various elements within the missile in accordance with such stored program thereby to produce control signals for the missile's flight control mechanism. The digital processor includes, in addition to a means for storing the macroprogram, a data memory and a microinstruction control memory. This latter memory stores sets of microinstructions, each one of such sets corresponding to one of a number of stored macroinstructions which make up the macroprogram. A register is provided which is adapted selectively to load an addressed microinstruction or a digital test word serially applied by means external to the missile. In such an arrangement the missile's digital processor may be readily checked out through a relatively simple interface mechanism. Also included in the digital processor is a set of addressable flip/flops adapted to be set or reset by signals both internal to and external to the processor. The state of an addresse one of the set of flip/flops serves as a condition signal used in the execution of various ones of the microinstructions. Means are also provided which are adapted to couple the output of the macroprogram storage means to the address inputs of the data memory thereby enabling retrieval of both an instruction from the macroprogram memory and its corresponding operand from the data memory within a single clock pulse interval. This invention wherein described was made in the course of or under a contract or subcontract thereunder, with the Department of Defense.</p> |
