    Data Acquisition and Display (DAD) language offers enhanced microcomputer performance for signal processing. This structured programming language enables faster execution and supports diverse data structures for 8-bit data acquisition.

    Area of Science:

    • Computer Science
    • Software Engineering
    • Embedded Systems

    Background:

    • Microcomputers based on 8080 and Z80 processors require specialized languages for efficient signal acquisition, processing, and display.
    • Existing high-level languages often present performance limitations for real-time data handling tasks.

    Purpose of the Study:

    • To introduce the Data Acquisition and Display (DAD) language, a novel programming solution for 8080/Z80 microcomputers.
    • To demonstrate DAD's capability in accelerating signal acquisition, processing, and display operations.
    • To highlight DAD's compatibility with structured programming paradigms and efficient hardware utilization.

    Main Methods:

    • Implementation of DAD as an interactive compiler utilizing a hardware arithmetic processing unit connected to the S100 bus.

  • Support for multiple data structures including floating point, double-precision integer, and single-byte integer for 8-bit data.
  • Integration with peripherals supporting unsigned-magnitude or 2's-complement formats and utilization of a hardware programmable interval timer.

    • Main Results:

    • DAD exhibits significantly faster instruction execution compared to most high-level languages.
    • The language effectively handles 8-bit resolution data acquisition and processing.
    • Seamless operation under the CP/M operating system for console and disk I/O.

    Conclusions:

    • DAD provides a powerful and efficient language for microcomputer-based signal acquisition and display applications.
    • Its design facilitates high-speed data processing and flexible peripheral interfacing.
    • DAD represents a significant advancement for real-time data handling on 8080/Z80 systems.
