Hi, all. I build an Apple-I clone on the Spartran3 starter kit, and placed it on my web site. http://www.ip-arch.jp/indexe.html The all logics are written with SFL, but you can convert to verilog with my tool (sfl2vl) on the above site. The archive includes logic files under SFL folder Xilinx UCF and BMM and MEM files and BIT file under Xilinx folder and readme.txt (attached bel...

Hi, I am working on a project which requires an ARM processor (hard core or softcore) to be put on a fpga. Basically the project targets on Hardware-Software Integration to improve the performance of cryptographic algorithms. Some parts of the algorithm work on ARM processor and parts of the algorithm which are computationally intensive are built on FPGA for hardware acceleration. I ha...


MMIX on FPGA

(I tried to ask something similar a few days ago, but have yet to see it on the list-- please forgive me if this is a duplicate. I could be misremembering, but I seem to recall somebody (perhaps Tommy Thorn?) saying that they knew of someone working on creating an FPGA version of Knuth's MMIX CPU. Does this ring a bell with anyone? Anyone know the status of this project, or how to g...


A High Performance 32-bit ALU

I decided to post the "best" ALU I've seen so far in the hope some people here can profit from it and help me improve it. Obviously what is "fast" and "general purpose" is relative, but it should be able to support the operations needed for MIPS and similar, that is, all the basic logical operations (OR, AND, XOR, NOT, ...) as well as add, sub, cmp, ..., and must include a bypass path. I tri...

Hi, It looks like this group has been slumbering for a bit. This seems to be the ideal place to have my discussion, but I'm not sure if there will be anyone listening? I see that there are lots of members of this group, but not many postings. I am returning to my project to implement a small CPU in an FPGA. I had looked at some of Jan Gray's work back in 2002 or so. I don't see wh...

hai all , i am arun . i am working on interfacing SD card using FPGA. i am using SPI mode of communication to SD card . 1. i wrote the code in verilog for the identification mode , i generated clock frequency of 100 khz to SD clk then i kept the SD card clock cycle to run for 74 cycles with CS high 2. after lowered the CS to 0 and gave the command 0 i.e 40_00_00_00_00_95 (hex) to the...

Hello, I have decided to use c3088 camera which uses ov6620 from Omnivision on my project. I would like to grab 2 frames into the FPGA. The camera has VSYNC, HREF, PCLK AND 8 bit for each pixel data. VSYNC tells us the start of a new frame, HREF tells us the start of new line while PCLK tells us a new pixel coming in. The camera provides 352x292 pixel but I'm only interested in the 1st ...
