    BrandonAzbell
    Camila Nunes The device is TMS320C6202 DMA. A document I would suggest using is the TMS320C620x/C670x DSP Program & Data Memory Controller/DMA Controller . This will provide the high level architecture of the DMA and how it is hooked into the CPU memory system. The DMA on the C6202B has...

  • Forum Post: HPI control problem

    Vladimir Podosinov
    Hello, I am interfacing an ADC to the HPI bus on the TMS320C6455. I know that HPI is a slave peripheral, and that actually makes a lot of trouble for me, but unfortunately there is no other choice for parallel ADC as EMIF is already taken by other device. ADC provides it's own clock (40 MHz), so...

    Craig Neely
    Hi Brandon, Thanks for the reply. That's good news that the EMIFA port is 3.3V as it means I can go to the DM6437's HPI w/o level shifters. Are you certain on the GPIO port? I was guessing it was 1.8V as the Lyrtech schematics for the EVM have boot mode pull-ups to 1.8V on those pins for...

    Craig Neely
    Hello, I'm designing a board around the C6457 processor and I can't find an important bit of info in any of the data sheets. Which bus voltage do the EMIFA, HPI, and GPIO peripheral ports use? 1.8V or 3.3V? I'm embarrassed to ask something so basic, but I've looked everywhere I...

    Fabion et Fronk
    Hello, we do have a question regarding the multiplexed GP0/HPI pins of the TMS320C6418 DSP. We are developing an universal DSP Board with this DSP and a MSP430F1481 microcontroller serving as host for this system. This µC should initialize the DSP via HPI16, whose pins are multiplexed with...

    Hi all OK, now we have the EMAC0 working, but the question is on a different topic I am trying to boot the tci6486 using the HPI port. I write all the code in the DSP memory, and then assert DSPINT according to TI documentation spruea7c. Guess what? It does not work. We translate the coff file...

    Hi yes, i can do that. I added an assembler interrupt vector, that loads at 0x800000 (0x10800000 global space) and jumps to _c_int00, as we did in older DSPs. I am not sure if this was the right thing to do, I am not sure if the software is running yet. We also have a new issue: after issueing...

    Hi yes, I do. Is it possible to connect to the board using CCS and avoid a halt on connect? I mean - while the DSP is running (or not...) , I connect the CCS and maybe break the program execution to see where I am stuck. Also, I wrote Tom that we have a new issue: after downloading and (maybe)...

    We are testing the HPI on the C6747 and are only having partial success. I believe I followed everything in the HPI user's guide needed for initialization. Here is what seems to work so far: The host device can write a value to Address read/write registers and read back this value. The host...

    Jimmy Setyo
    I am using TMS320C6555, and I am connecting HPI bus to FPGA's I/O pins. Since there's no internal pullups on C6455's HD[31:0], am I required to put external pullups on HD[31:0] ? I couldn't find the answer in datasheet nor design checklist. The only thing that I found in the...

    I'm using C6455 EMIF to connect to a C5510 HPI. All data transfer's working great, but I'm running into a race condition which I can't seem to figure out how to solve. Here's the setup: I've got a couple of ring buffers on both the C6455 and C5510 as well as a couple of memory...

  • Forum Post: C6414T HPI Operation Question

    TommyG
    C6414T is interfaced to host with HCSn tied low. The HRDYn signal never goes high when host is reading from DSP except at RESET. Is it a requirement that HCSn transition High to Low for HRDY to change states? In SPRU578C, last paragraph of sec 3.7, it states that HCSn gates the HRDYn output. In other...

  • Forum Post: C6457 HPI Maximum Sustained Throughput

    TommyG
    According to data manual (SPRS582B, sec 7.12.3) it seems that tw(HSTBL) + tw(HSTBH) are the specifications that define how fast the interface can operate. The value for 1.2 GHz CPU is 25 ns or 40 MHz which in HPI32 mode gives 160 MB/sec theoretical maximum. Is this a correct interpretation? Is there...
