General system design

General System Design

  • Motorola MC9S12C128

    w/ 16K Fixed Flash EEPROM, 4K Bytes RAM

  • Memory Requirements for Project

    8K ROM, 1K RAM


Kernel selection

Kernel Selection

  • Time Slice kernel

    • Time slice Period of 10ms

    • Bus frequency of 24MHz

  • Estimated Memory Requirements :2K


Task designation

Task Designation

  • 5) Switches and Shock Sensor Input task

  • 6) State Control task

  • 7) Pressure Sensor Input Task


Switches and shock sensor input task

Switches and Shock Sensor Input task

  • Description: Gets the input data from all switches and shock sensor.

  • Execution Time: 1.17us

  • Period: 10ms

  • CPU Load: .000117


State control task

State Control Task

  • Description: The system starts in the ARMED state. If the AlarmSignal variable was set from the switches and sensor task, it would go into the ALARM state

  • Execution Time: 1.54us

  • Period: 10 ms

  • CPU Load: .000154


Pressure input sensor task

Pressure Input Sensor Task

  • Description: Provides a high output signal and temperature compensation

  • Execution time: 10us

  • Period: 10ms

  • CPU Load: .001


Estimated cpu load

Estimated CPU Load

L = .000117+.000154+.001 = .00127

LMAX = .13%
