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

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

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...

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

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...

There are a lot of books that describes how to implement a FIFO One of them is VHDL for Programmable logic by Kevin Skahill Good Luck!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

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...

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...

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...

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!

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...

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

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%...

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.

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?

Well, I downloaded the Intel Application Accelerator as cdogg suggested and below you can see some details on my IDE controller and the MAXTOR Hard drive (I guess that the problem could be with the 40-Pins cable): Controller Information IDE Controller: Intel(R) 82801BA Ultra...

Thank you all for your help!!! Here's a little more info on my computer: I use ASUS P4B266 with Intel's 1.6G P4 (100MHz external bus),and 256MB of RAM. The Primary IDE, which connected only to the Hard drive supports and use UltraDMA When I first started using this Hard Disk I formmatted it...

Well, Before I installed my new hard drive I formatted the disk. do you think that I will need to format it again?

Hi, I replaced my hard disk to MAXTOR 40.0GB DiamondMax Plus 8 ULTRA ATA133 IDE 7200RPM. I use Pentium 4 1.6GB and Win2000. Since i replaced my hard disk my computer is very very slow. When I open the task manager I can see that the CPU is 100% used and the processes that uses it are software...
