    VHDL Asynchronous Reset Not Working!

    I can guess that the reset polarity is oposite (should be if A_Reset = '0' then) Avi

    Test Bench compilation error

    The Data signal should be a four bit signal and the OpCode should be a 3 bit signal size but they are both defined as Operand. The Operand type in your Alutypes library is probably defined as a 1 bit size. Avi

    COS & SIN functions in VHDL

    Thanks for your replies! The reason I need these functions is that I need to implement conversion from Polar form to Rectangular form in FPGA (for Image processing) I downloaded a CORDIC core from the opencores wesite but the Polar form to Rectangular is not implemented there yet (only...

    COS & SIN functions in VHDL

    Hi, Does anybody know how to implement cos/sin functions in VHDL. Or even better, is there any on the shelf IEEE cos/sin functions? Thanks

    Altera's ByteBlaster II

    Hi, I'm intending to use Altera's EPCS4 serial configuration device and i noticed that it requires a new configuartion cable (ByteBlaster II). The old configuration cable (ByteBlasterMV) data sheet included a schematic of the cable. ByteBlaster II data sheet is missing the electrical schematic...

    multiple rising edges(clocks), falling edge

    hi, if you have a clock in your design then you can detect rising and falling edges by synchronising these signals to the clocks and using one or two (if you want to be sure that you're not sampling noises) Flip Flops and comparing the input signal and the output of the Flip Flop example...

    KMODE_EXCEPTION_NOT_HANDLED

    Hi, first of all i want to thank all of you who helped me through this despairing problem. Finaly my computer works as it supposed to be. I formatted my HD and Installed all my programs again. I think that SESaskDFC was right and a virus was eating my computer's resources and it is true that it...

    KMODE_EXCEPTION_NOT_HANDLED

    My computer became to be very wierd in the last fiew days: I upgraded my HD from 10G to 40G and I noticed that the CPU is almost 100% used even in Idle operation (described in another thread). After that my CD-R/RW stoped working. It was recognised in the BIOS and in the task manager but when I...

    100% use of CPU after Hard Disk Replacement

    bcastner, I'm sorry but I'm not familiar with the WMI. Can you please explain in more details what should I do? thank you!

    100% use of CPU after Hard Disk Replacement

    The reason I knew that these two processes (and others) are taking 100% precent of CPU usage is that I saw it in the processes window in Task Manager. an interesting observation is that even when I close all the programs include all the ones that usualy runs on windows startup (clearing them...

    100% use of CPU after Hard Disk Replacement

    A small correction: when the system is idle the CPU diagram in the task manager is almost full (shows 70-80% usage)

    100% use of CPU after Hard Disk Replacement

    Two examples: A Tetris game (TetriStation) and an installation of windows update. I stated these examples in purpose because they shouldn't use more than 20-30% of the CPU. another thing that is weard is that even when the system is idle the CPU diagram in the task manager is full (shows 100%...

    100% use of CPU after Hard Disk Replacement

    Well, finally I,ve got a 80 pin conductor and now the HD is in UDMA-5 transfer mode. But... unfortunatly the problem continue as it was before The CPU is in 100 percent use. I'm a little hopeless because I think that the solution will be to reformat the hard drive again.

    100% use of CPU after Hard Disk Replacement

    I have a "stupid" question: how can i recognise a 40-Pin cable or in another words what is the visualy difference between the 40 and 80 pins cables?
