DURA Automotive Systems Selects Green Hills Software's Platform for Advanced Driver Assistance NXP FTF Technology Forum - Green Hills Software, the worldwide leader in high assurance operating. The Greenhills License Manager (or GHS LM) is a license manager that is mandatory for all GHS software running on a host machine (as opposed to their embedded products for IoT and other devices). There are 4 available license models. DURA Automotive Systems selects Green Hills Software’s platform for Advanced Driver Assistance Green Hills Software, the worldwide leader in high assurance operating systems, today announced.

GStreamer, DSP/BIOS and DSP Link™, found on e.g. Texas Instruments DaVinci.

DSP/BIOS Link or DSPLINK is an IPC (interprocessor communications) scheme for passing messages and data in multiprocessor systems. In the case of the DaVinciDSP family from Texas Instruments, this scheme would allow passing of messages and data between an ARM client and a DSP server. DSPLINK can be used to implement a layer of software abstraction called a RPC that allows a remote function on the DSP to appear as local function calls in the ARM application code. The Codec Engine IPC communication layer is implemented using a RPC call scheme built on top of DSP/BIOS LINK.

Overview[edit]

DSP/BIOS LINK is implemented using shared memory and internal interrupts[clarification needed] from the ARM to the DSP and vice versa.

The shared memory protocol for IPC is implemented as follows:

  1. The ARM and DSP are programmed to a pre-determined memory address where a message will be sent from the ARM to the DSP; and another for messages sent from the DSP to the ARM.
  2. One processor sends messages to the other by writing the message into the pre-determined address and then sending an interrupt to signal the other processor that a new message is available. When transferring data buffers, only a pointer to a given buffer needs to be passed since the buffer resides in shared memory that is accessible to both the processors. ARM buffer addresses must be translated into physical addresses when being presented to the DSP, as the DSP does not have an MMU or a concept of virtual addressing.
  3. Once the processor receiving the message has read it, it marks a flag in shared memory to indicate that the message memory is now available to be rewritten with another message.

The DSP included in many DaVinci-based devices generally runs TI's DSP/BIOSRTOS. When multiple, heterogeneous cores are included in the device (e.g. DM644x), DSP/BIOS Link drivers run on both the ARM processor and the DSP to provide communication between the two.

Operating systems[edit]

A number of ARM9 operating systems support DSP/BIOS Link drivers:

  • QNX Neutrino
  • LEOs (RTOS)
