Overview

The DB8279 Programmable Keyboard / Display Interface core is a full function equivalent to the Intel 8279 / Mitsubishi 8279 / NEC uPD8279 devices.

The DB8279 simultaneously and independently interface a keyboard and display to a microprocessor. The keyboard section provides a scanned interface to a 64-contact key matrix keyboard. The display section contains a 16x8 display RAM which refreshes a numeric or alphanumeric segment display.

Key features

  • Simultaneous and independent scanning of a keyboard and refresh of a display, significantly offloading these functions from the microprocessor.
  • Keyboard section:
    • 8-character Keyboard FIFO
    • 2-Key Lockout or N-key Rollover with Contact Debounce
    • Interrupt Output on Key Entry
    • Programmable Keyboard Scan & Debounce rates
  • Display Section:
    • Dual 8- or 16-Numeric Display
    • Single 16-Character Display
    • Right or Left Entry 16-Byte Display RAM with address autoincrement
    • Programmable display refresh rate
  • Available in VHDL, Verilog, or FPGA-Specific Netlist

Cortex-M And Classical Series ARM Architecture Comparisons

ARM has introduced many processors. Each set or groups of processors are having different core and different Features. A new entrant or Designer to the ARM can make use of this paper for easy understanding and choose a processor that is well suited for the requirements. This paper gives brief comparison of the Architectures.

DDR2 Signal Integrity

This paper highlights a typical design approach that can be adopted for an embedded PC (X86 based) board memory subsystem using a VIA VX700 system controller DDR2 interface. Boards with this chipset can feature either an Intel Pentium processor or VIA processor on front side bus (FSB).

Extreme partitioning

Small changes in the initial design of a complex embedded system can often have an unpredictable outcome and have a significant impact on the final system performance
