Introduction

DSP Link is foundation software for the inter-processor communication across the GPP-DSP boundary. It provides a generic API that abstracts the characteristics of the physical link connecting GPP and DSP from the applications. It eliminates the need for customers to develop such link from scratch and allows them to focus more on application development.

The DSP/BIOS RTOS is expected to be running on the DSP.

Device Support

This release supports the following devices. Note that for licensing reasons, different OS's may require you to obtain different downloads (e.g. Linux downloads are licensed GPL, but WinCE downloads are licensed BSD).

• DM6446 EVM:
  • multiprocessor configuration, running Linux (GPP) and DSP/BIOS (DSP)
  • multiprocessor configuration, running WinCE (GPP) and DSP/BIOS (DSP)
• DM6467(T) EVM:
  • multiprocessor configuration, running Linux (GPP) and DSP/BIOS (DSP)
  • multiprocessor configuration, running WinCE (GPP) and DSP/BIOS (DSP)
• OMAP3530 EVM:
  • multiprocessor configuration, running Linux (GPP) and DSP/BIOS (DSP)
  • multiprocessor configuration, running WinCE (GPP) and DSP/BIOS (DSP)
• OMAP-L1XX EVM:
  • multiprocessor configuration, running Linux (GPP) and DSP/BIOS (DSP)

Other devices and configurations supported in DSP Link 1.65.00.03 should also be supported. Device support was not removed, although validation of this release is limited.

Validation

This release was built and validated against using the following software components:

• DSP/BIOS 5.41.03.17

This release was validated using the following hardware platforms. Note that other devices and configurations supported in DSP Link 1.65.00.03 should also be supported. Device support was not removed, although validation of this release was limited.

• OMAP3530 EVM:
  • multiprocessor configuration, running Linux (A8) and DSP/BIOS (DSP)
• OMAP-L138 EVM:
  • multiprocessor configuration, running Linux (ARM 9) and DSP/BIOS (DSP)

Version Information

This product's version follows a version format, M.mm.pp.bb, where M is a single digit Major number, mm is 2 digit minor number, pp is a 2 digit patch number, and b is an unrestricted set of digits used as an incrementing build counter.

To support multiple side-by-side installations of the product, the product version is encoded in the top level directory, ex. dsplink_1_65_01_06.

Subsequent releases of patch upgrades will be identified by the patch number, ex. DSP Link 1.65.01.XX with directory dsplink_1_65_01_XX. Typically, these patches only include critical bug fixes.
