FFTW Home Page. Keep it simple, Stupid! [OMAPL138] Hello DSPLink Program - OMAPL1x Processors Forum - OMAP™ Processors - TI E2E Community - Iceweasel. It'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. DSPLink POOL FAQs - Texas Instruments Embedded Processors Wiki - Iceweasel. DSP Link is still available for download, but no further releases or updates are planned.
Please see IPC Software Options for details and alternatives. This page contains Frequently Asked Questions for the DSPLink POOL module. OMAP3 DSP MMU Configuration - Texas Instruments Embedded Processors Wiki - Iceweasel. 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. However, with a TLB miss the translation will have to be retrieved from the translation tables which would be a less optimal with regards to performance.
For detailed description of the MMU for OMAP35xx see the following manual. DSP MMU Faults - Texas Instruments Embedded Processors Wiki - Iceweasel. Enabling trace in DSPLink - Texas Instruments Embedded Processors Wiki - Iceweasel. DSP Link is still available for download, but no further releases or updates are planned.

Audio Soc example - Texas Instruments Embedded Processors Wiki - Iceweasel. 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 example application uses a DSP-side output audio driver application in-conjunction with an ARM-side application to pass (via a file) raw Pulse-code Modulation (PCM) data to the DSP for processing using Texas Instruments DSP/BIOS Link software stack. Note: This example is not intended to solve system issues when running peripheral drivers on SOC devices (ARM + DSP cores) but as a starting point for developing applications to take advantage of peripheral drivers on both cores.
Example application using DSP Link on OMAPL1x - Texas Instruments eXpressDSP Software Wiki - Iceweasel. DSPLink Memory Map Tutorial [ETH PIXHAWK MAV: Computer Vision on Micro Air Vehicles] - Iceweasel. 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. DSPLink API Guide [ETH PIXHAWK MAV: Computer Vision on Micro Air Vehicles] - Iceweasel. 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. Introduction. Category:DSPLink - Texas Instruments Embedded Processors Wiki - Iceweasel.

DSP/BIOSTM Link overview DSP/BIOS™ LINK is foundation software for the inter-processor communication across the GPP-DSP boundary. Texas Instruments - Iceweasel. BeagleBoard_DSPLink – OSSIE - Iceweasel. 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. DSPLinkGuide - creation-station - This page is under ongoing construction. I'm hoping it will snowball into an idiot's guide to using the DSPLink on the BeagleBoard. There are a number of resources online for the DSPLink, and this p - Project Hosting on G. 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).
