[OMAPL138] Hello DSPLink Program - OMAPL1x Processors Forum - OMAP™ Processors - TI E2E Community - IceweaselIt's been a few days, no much progress. What I have done is: 1, Re-configured the dsplink using command: perl dsplinkcfg.pl --platform=OMAPL138 --nodsp=1 --dspcfg_0=OMAPL138GEMSHMEM --dspos_0=DSPBIOS5XX --gppos=ARM --comps=ponslrmc --trace=1 --DspTskMode=1
From Texas Instruments Embedded Processors Wiki Translate this page to DSPLink can be used by itself, or as part of Codec Engine (CE) . This page gives details of changing the DSPLink memory map when used 'raw'.
From Texas Instruments Embedded Processors Wiki Translate this page to This page contains Frequently Asked Questions for the DSPLink POOL module.
From Texas Instruments Embedded Processors Wiki Translate this page to What are TLBs? The OMAP35xx MMU has Translation Lookaside Buffers (TLB). The TLB is a cache the allows the MMU to accelerate virtual to physical address translation by holding the most recent translations. For example if there is a TLB hit then the translation will be retrieved from the TLB cache.
From Texas Instruments Embedded Processors Wiki Translate this page to Some TI processors such as the OMAP3530 have a memory management unit (MMU) for both the ARM and the DSP.
From Texas Instruments Embedded Processors Wiki Translate this page to Overview In certain kinds of failures seen in applications, sometimes the system just hangs without a kernel crash dump.
From Texas Instruments Embedded Processors Wiki Translate this page to Introduction The audio Soc example is a demo application that illustrates the use of DSP-side peripheral drivers running in conjunction with a Linux kernel application on a ARM processor for select Texas Instruments Soc (System on a Chip) devices. This example contains both a DSP-side and an ARM-side application.
The memory map is necessary to define the memory areas where Linux and DSP work on. It can be adjusted to the needs of the application. Instructions how to calculate the size based on the application can be found below. Via the Linux bootloader (u-boot) the Kernel software has to be informed which RAM regions they should use.
Learn here what DSPLink is, what it can be used for and how to use it. The complete toolchain is described on the OMAP3 DSP Toolchain page. The installation of a Windows or mixed Windows/Linux toolchain is also described in detail there. The installation for OpenEmbedded builds is described in the DSPLink installation guide .

Contents: There are multiple options of how to make use of the onboard TI TMS320C64x+ DSP. The first step is to install the GPP/DSP interface. Two of the more popular interface options are DSPBridge and DSPLink. Both were developed by TI but DSPLink is still supported, which makes DSPLink a more preferable option.
After digging around online and chatting it up on the #Beagle IRC channel, it seems like a lot of people are using the BeagleBoard as a tiny ARM/Linux box. While this is all well and good, the beauty of the OMAP is the DSP sitting next to the ARM. We set out to create our synthesizer using the DSP to generate, filter, and transform audio waveforms; however, much to our dismay, using the DSP is no easy task. Armed (hah, that could be a pun..) with extremely limited Linux skills, this page documents our approach to concurring DSPLink. In the BeagleBoard 's OMAP3530 and similar processors, Texas Instruments has included a general purpose processor (ARM) and digital signal processor (DSP).
