PS2_W - Wishbone PS2 Controller
Figure 1. PS2_W - Wishbone PS2 Controller.
The PS/2 Controller component (PS2_W) provides a bidirectional, synchronous serial interface between a host processor and a PS/2 device (keyboard or mouse).
Supply of these soft cores under the terms and conditions of the Altium End-User License Agreement does not convey nor imply any patent rights to the supplied technologies. Users are cautioned that a license may be required for any use covered by such patent rights.
Features at-a-glance
- IBM PS/2 device compatible (keyboard or mouse)
- Bidirectional transmission (synchronous and serial).
- Hardware parity (odd) check on all data received from PS/2 device
- Hardware parity (odd) generation on all data sent to PS/2 device
- Wishbone-compliant
Availability
From an OpenBus System document, the PS2 Port component can be found in the Peripherals region of the OpenBus Palette panel.
From a schematic document, the PS2_W component can be found in the FPGA Peripherals (Wishbone) integrated library (FPGA Peripherals (Wishbone).IntLib), located in the \Library\Fpga folder of the installation.
