• RE: BF54x mobile DDR guidance

    Hi Tim,

    The suggested VDDDDR nominal voltage for mobile DDR on the BF54x is 1.875V. You can look at the operating conditions on page 34 of the ADSP-BF542/ADSP-BF544/ADSP-BF547/ADSP-BF548/ADSP-BF549 Blackfin Embedded Processor Data Sheet (Rev C, 02/2010…

  • RE: VDDMP on BF548

    Hi,

    If you are using MXVR the ferrite bead and capacitance are recommended in the MXVR Board Layout Guidelines section of the ADSP-BF542/ADSP-BF544/ADSP-BF547/ADSP-BF548/ADSP-BF549 Blackfin Embedded Processor Data Sheet . If you aren't using MXVR, then…

  • BF544 pin assignment

    I'd like to develop a dsp board based on ADSP-BF544BBCZ.

    Eventhough it is a subset of BF548/9, I should know the real pins and assignment to draw schematic.

    But I cann't find exact pinout of BF544 device. I've checked ADSP-BF542_BF544_BF547_BF548_BF54…

  • RE: ITU-R BT.656 to digital RGB666 conversion

    I have taken a look at the blackfin processors. I assume that I need one with at least 2 PPI ports. This means that I need to use the ADSP-BF544 or better. According to your website this ‘low-cost’ DSP costs $16.56 at a 1000 pieces, which is far too expensive…

  • Host Memory Mode on Blackfin Processors?

    I'm currently using the ADSP-2186 DSP, and I'm looking to migrate to the
    Blackfin processors. Do Blackfin processors support anything like the Host
    Memory Mode on the ADSP-2186 DSP?

     

    The newly introduced ADSP-BF54x Blackfin Processor…
  • Power Estimates for ADSP-BF54xx (specifically 544)

    I know that there are power estimation tools for older BF families like the 537 but I cannot seem to find any power numbers for the ADSP-BF54x family? Are there any and if not where can I find some rough numbers based on operating modes? Thanks!

  • ADSP-BF544高温(60~70度)无法启动

    现有模件使用ADSP-BF544芯片,部分器件发现在拷机过程中高温无法重启

    后用热风枪单独加热芯片,大约在70度左右CPU无法启动。

    CPU运行程序为只有点灯功能的小程序,高温重启无法点灯。

    但在故障情况下使用仿真器连接是可以正常运行的。

    出现芯片的版本为0.4版。各个批次,新加坡封装,国内封装都出现过问题。

    能否帮忙分析一下问题,或者是否有CPU上电读取程序的时序。

    出错时候CPU内部到底发生了什么能否判断?

    以下为故障时CPU从FLASH读取数据时序

    D0为数据线D0,READ为…

  • RE: gstack-like utility

    Hi,


    I'm not sure how useful this is but from VisualDSP++ Update 9 we added support for detecting when an application's stack size increases beyond its allocated size. You will find more information on page 9-8 of the attached Release Note for Update…

    Hi Alex,

    as VisualDSP++ 5.0 was released almost 3 years ago, there have been a number of bug fixes and improvements to the tools throughout the updates we have issues in that time.
