PL050_KMI component

This section describes the PL050_KMI component.

PL050_KMI - about

ARM PrimeCell PS2 Keyboard/Mouse Interface (PL050). This model is written in LISA+. It communicates with models of PS/2-like devices such as a PS2Keyboard or PS2Mouse.

PL050_KMI contains the following CADI targets:

  • PL050_KMI

PL050_KMI contains the following MTI components:

PL050_KMI - ports

This section describes the ports.

Table 4-136 PL050_KMI ports

Name Protocol Type Description
pvbus PVBus Slave Slave port for connection to PV bus master/decoder
intr Signal Master Master port signaling completion of transmit or receive
clock ClockSignal Slave Clock input, typically 1MHz, which sets the master transmit/receive rate
ps2device PS2Data Slave Used to communicate with a PS/2-like device

PL050_KMI - registers

This section describes the registers.

PL050_KMI - verification and testing

This component passes tests as part of the VE example system by using VE test suites and by booting operating systems.

PL050_KMI - performance

This component is not expected to have a significant impact on performance of a PV system. However if it is connected to the Visualisation component, then the performance of the component depends on that of the visualization.
