  • Forum Post: How do I manage the hardware memory page boundary in C55x processors?

    Naser Salameh
    Fix In the TMS320C55x CPU revision 2.1/2.2, memory is organized in pages of 64K words due to the fact that many aspects of the architecture are limited to 16-bits (the A-unit ALU and the ARn registers are some examples). Although the C55x data addresses are 23 bits, address calculations done by the...

  • Forum Post: C5000 Support on CCS 3.1

    mjones
    How can I find out if my version of CCS 3.1 supports C5000? The version we run pre-dates my time at the company and claims support for all processor types in the Component Manager, but I have no C5000 options in the setup window. Any ideas?

    BrandonAzbell
    CCS v3.1 did have a version that was targeted specifically for the C2000 family only. The full, or Platinum version, would have had support for all devices at that time but did not include any C64x+ based devices. Does your installation of CCS v3.1 have the code generation tools for C5000 installed...

    E2E_display_name_Mike
    After a little more testing and consulting with Brad, it turns out the culprit is a function called minit(). This function seems to be allowed in a non-BIOS project, but causes problems in a BIOS project. The easy work around is to not use this function and this option will work in my case. There are...

    Hi, I am using DSK5510 fixed-point board. It has TLV320AIC23b audio codec. I am trying to generate a sine wave with DC offset (for modulation) but I see its AC part only when I view sine wave on oscilloscope. Is AIC23b AC coupled? Thanks, Abhishek Seth.

    Brian Willoughby
    I have read SPRU596A and SPRU511 as well as scanned the csl_usb.h header, and I think I have a decent start on programming a USB Device firmware for the C5506. However, it would really help to see some sample code. I could not find anything installed with CCS3. Any pointers would be welcome.

    I'm familiar with the 55xx assembly instruction SAT, and the associated compiler intrinsic, _lsat( ). These seem to be intended for signed arithmetic. My question is: Does there exist a comparable facility for unsigned data? BTW, it would be nice if there were a single consolidated list of all...
