Hi jidan, We are having trouble inputting the numbers.How do you input the floating point numbers? We are doing it in VHDL language.How do we convert the...
Hi, I think that is mentioned in the documention. Not only do you have to convert it to binary, but also to a IEEE-754 binary format. Use a special caluclator...
Hi Jidan, Thanyou for your last mail.We were having trouble converting the floating point numbers to binary.Do you have the code for it? If possible can we get...
... converting the floating point numbers to binary.Do you have the code for it? If possible can we get the code for addition and subtraction of FPU in VHDL. ...
hi jidan . i am very much confused with the exception unit in floating point unit. we have to do seperate module for exception unit or we can combine the...
Hi, The project website for fpu100 at opencores.org says that the fpu is pipelined. Does that mean that it is possible to give the next set of operands to the...
Hello sir . Thank u for ur mail. We can give the next set of operands only after the number of cycles completed. The modifications to be done in the project...
... Hi Advait, Sorry for replying late. For some operations e.g. addition/subtraction (somebody please correct me if I am wrong), you don't have to wait until...
Hello, This email message is a notification to let you know that a file has been uploaded to the Files area of the 32bit_fpu group. File : /fpu_v19.zip ...

Jidan, is this corretion also in the CVS? Martin...
No, I still didn't. When I uploaded the code, I tried also to update the CVS, but the program I use (WinCVS), always crashed. I will try to solve this over the...
... serial multiplier is used (thanks to Chris Basson!) ... Done! Thanks, please keep this list informed when you update your FPU as I'm also including it in...
The instructions for getting test vectors suggest running timesoftfloat. However, that program was designed not to test the accuracy of the results, just to...
I've gotten the fpu-100 core to work using Modeltech (on Linux), but I haven't been able to get the included test-bench to work. This because of my limited...
It is working now. I'm not sure what the difference between my build environment at work and at home is, but I have it working at home (Ubuntu 7.04/i386) now....
I do not have the problem of no vectors testing the square root (a 100 in the third line of the text block), but I have the same repetition issue you mentioned...
... I skimmed the file timesoftfloat.c fpu_v19 and from John Hauser. The line: minIterations = 1000 is changed to minIterations = 100000 and there are some...
Hi everyone! For the past few months I've worked on a comparison between the FPU and a Softfloat implementation in Java running on an Altera FPGA with JOP, the...
I agree, there's a bug. I think it's in post_norm_mul.vhd, in the process that sets s_shl2 and s_shr2 (starting around line 145 in my copy, though I may have...
Hello; I will work with parallel architecture, That's why i need to know the development of code sources of microprocessor to choose a subsequent architecture...
Hello, i have the fpu_v19 Version of the FPU. All arethmetic operations works, but not the multiplicate. I get a wrong result. For example: 10 000 000 * 1.212...
I see that nearly all of the messages posted here in the last year are just spam. Is anyone still watching this group? Are there other users of the FPU...
this is a great little fpu core. I played with it a bit, then wanted to make some improvements, features enhancement. But the original author is mostly...
How about the group moderator, is he around? We can at least get rid of the spam by changing the way new users are approved. I do that with about a dozen...
We also identified bugs in dealing with un-normalized numbers (when the exponent has the value "0", there is special treatment of the mantissa), and the...
