The Fusion Real Time Operating System (RTOS) for The PowerPC is the worlds most widely used fully-featured Operating System for PowerPC.

The Fusion RTOS is optimized for 16/32-bit networking and media-centric processors. It is priority based, pre-emptable, deterministic, and protects against priority inversion. The RTOS has been fully ported and optimized for The PowerPC DSP.

For details on the supported capabilities please refer to the PowerPC Users guide. This guide may be downloaded from the Technical Manuals section of the web site. For general RTOS information please go to the RTOS home page.

Power PC Embedded RTOS Features

The Fusion RTOS supports three major areas:

• Hardware Interrupt Management.
• Power Management.
• Uart, Print and Command Line support.

  Interrupts:

  The Fusion RTOS for PowerPC provides a full software feature set to control and manage interrupts as follows:

  • Direct Task synchronization from an interrupt handler.
  • Allows interrupt handlers to be written in C.
  • Supports Nested Interrupts.
  • Provides for delayed task reschedule from the interrupt dispatcher.
  • Interrupt handlers may be dynamically installed or removed.
  • Support for direct vectored interrupts.
  • Allows for control of wake on interrupt configuration for each interrupt.
  • Provides easy interrupt installation by peripheral name.
  • Provides disabling interrupts for a specified peripheral.
  • Provides disabling/enabling of all interrupts.
    
    

  Power Management:

  The Fusion RTOS for Power PC provides full software support for power management:

  • Provides complete PLL control.
  • Provides control of PLL frequency.
  • Provides PLL Bypass and Engage functions.
  • Provides Core and Bus frequency control.
  • Provides Core Voltage control.

  Command Line Interface:

  The Fusion RTOS for PowerPC provides a uart management mechanism for printing text, variables and taking character input. Please review the Fusion SHELL users manual for complete details concerning the command line interface and printing capabilities.

  • Example Uart driver for send and receive.
  • Integrated with the Fusion SHELL command line.
  • Provides support for Printing text and variables.
  • Provides support for fosGetChar function calls.

  Integration:

  The Fusion RTOS for Power PC has been integrated with a number of Fusion products, and on-going development work continues to expand this integration. Currently supported Fusion Products are:

  • Fusion Net. The full suite of networking products.
  • Fusion File. The Fusion Flash File System. FAT12/16
  • Fusion Web Server
  • Fusion Web Browser. (In Progress)
  • Fusion HTML GUI. (In Progress)
