  • Patent number: 4449185
    Abstract: In a data processing system having a memory and employing N-bit bytes and two byte addresses, a branch instruction which can cross one page boundary is executed without having to use calculations to effect a change in the contents of the program counter (PC). It is determined whether the value V1 of the (N-1) least significant bits (LSB's ) of the lower order byte of the two byte branch address is greater or less than the value V2 of the (N-1) least significant bits (LSB's) of the lower order byte of the address to which the PC is pointing and also whether PC N.noteq.BR N where PC N and BR N are the most significant bits of the lower order bytes of the PC address and the branch address, respectively. If V1<V2, PC N=1, and PC N.noteq.BR N, the upper order byte of the PC address is incremented by 1 and if V1>V2, PC N=0, and PC N.noteq.BR 7, the upper order byte of the PC address is decremented by 1.

  • Patent number: 4445190
    Abstract: A method for use in an electronic digital signal processing system for improving execution time in locating requested programs, reducing program storage requirements in memory and improving packaging and repackaging of programs on direct access memory devices for the library. A program data set for a system is formed to recognize the references to character program names and to resolve those references into control section identification codes. Each referenced character program name is uniquely encoded to a 16 bit control section identification code used as an input to a table lookup routine. The encoded control section identification for the program library loaded on the direct access memory consists of a data set number, a module index number and a control section number. A similar data structure is used to locate programs in storage by program management once they have been retrieved from the program library stored on a direct access memory device of the system.

  • Patent number: 4443865
    Abstract: A processor module is one of several modules mounted in a rack to form a programmable controller. The module has a microprocessor that executes a sequence of machine language instructions to interpret and thereby execute macroinstructions that are part of a control program stored in a read/write volatile main memory. The rate of execution is improved by reducing the instructions in a fetch sequence used in coupling each macroinstruction to its interpreter sequence of machine-language instructions. Hardware assistance is provided to allow expansion of macroinstruction operation codes as they are fetched. The processor module also allows the user to program his own interpreter sequences for specially defined macroinstructions and to load these sequences into a nonvolatile memory that is plugged into the module. An external auxiliary power supply is connected to the processor module to supply the programming voltage required by the nonvolatile memory.

  • Patent number: 4443863
    Abstract: A data communications system for asynchronous communication having at least two data transmit/receive terminals wherein the display is periodically updated with new send or receive data. In the receive mode the data is accumulated in a receive buffer for a predetermined time interval and then transferred into a text storage buffer which then activates a display access method to process the stored data and update the display. The display access method then goes into an "idle" mode and waits for the next transfer of data which does not occur until the predetermined time interval has expired. In the transmit mode the send data is transmitted without a delay but the display is updated after the predetermined time interval has expired.
