  • Patent number: 4409671
    Abstract: A microprocessor on a monolithic integrated circuit is provided having a single clock input pin for receiving a clock input signal. The clock input signal is used to gate address data onto the address bus and to enable a data input dynamic latch. In addition the input clock signal is used to generate two complementary non-overlapping clock signals used for synchronizing purposes within the microprocessor.

  • Patent number: 4330842
    Abstract: A digital data processor on a single monolithic integrated circuit chip is provided which uses one less pin. The elimination of the pin is accomplished by using, internally to the processor, a valid memory address signal to gate information from the address but to an address output line. Whenever an address is not present on the address bus all logic "1's" are generated on the address output bus.

  • Patent number: 4266270
    Abstract: A microprocessor comprises an internal address bus having a first portion (2,4) having a plurality of conductors carrying the low order address byte and a second portion (10) having a plurality of conductors for carrying the high order address byte. The microprocessor further comprises a plurality of registers, including an incrementor (12,13), a program counter (14,15), a temporary register (16,17), a stack pointer (18,19), an index register (20,21), and an accumulator (22,24), each comprising a pair of 8-bit registers for temporarily storing information. An arithmetic logic unit (28) performs computational operations on digital information within the microprocessor. The microprocessor includes a pair of internal data buses (6,8) each having a plurality of conductors for conducting digital information within the microprocessor. Means are provided for coupling selected ones of the registers, or the high or low order portions thereof, to the first and second data buses.

  • Patent number: 4203157
    Abstract: A circuit and a method for adding an 8-bit operand to a 16-bit operand are disclosed such that the number of machine cycles required by a data processor to perform such an addition is reduced. The 8-bit operand and the least significant byte of the 16-bit operand are added together within an 8-bit adder circuit to generate the least significant byte of the result. Simultaneously, the most significant byte of the 16-bit operand is stored in a temporary register and is also input to an increment/decrement network. The adder circuit, after a given delay time, generates a carry signal depending on whether a carry-out was produced by the addition. The carry signal and the sign bit of the 8-bit operand control the mode of operation of the increment/decrement network and determine whether the increment/decrement network or the temporary register will be selected to provide the most significant byte of the result.

  • Patent number: 3943699
    Abstract: The thickness of an electronic watch body may be substantially reduced by having portions of the top surface of the watch extend above the remainder of the top surface. Components of the watch which otherwise result in requiring a thick watch body, such as the battery or the display element (e.g., a liquid crystal display), project up into these raised portions.
