Nexys 2 Spartan 3 FPGA Arrives

COMP-E — Sat, 07 Mar 2009 19:40:22 +0000

It took a week to get it from Washington state, but it’s finally here. My gorgeous Nexys 2 board I ordered from Digilent. It uses the Xilinx Spartan 3-e chip and has a lot of nice extra features that the one that Xilinx makes didn’t have. Digilent’s website also has a ton of cool addons for the board which I hope to get when there’s some money to spare. I’m going to start out slow and try and reacquaint myself a bit with verilog. My intent is to make a simple calculator and then perhaps move to converting my SLSL code for the 8085 over to verilog. The Nexys 2 board does come with some cool peripherals such as a ps2 port so I may get sidetracked and see what I can do if I hook up an old ball mouse too it. I’ll try to keep you all posted here so the RSS grabs it, but check the forum for code postings and photos. I’ll try to include links as things crop up.

Digital Design Implementing 8085

COMP-E — Sat, 07 Mar 2009 19:30:37 +0000

All op codes are not represented / implemented in this design however adding them should be very straight forward. This digital design utilizes a bus in order to achieve high efficiency and throughput. The design is scaled back a bit and uses less registers than the actual 8085. This can be easily modified though. Additional op-codes can also be added. Included in this post is are the .src (source) .fmt (format/debug) files. Note that the ‘cpu’ is reading op codes from memory not a .in file!

Five Surgeons

Five surgeons were taking a coffee break and were discussing their work. The first said, “I think accountants are the easiest to operate on. You open them up and everything inside is numbered.” The second said, “I think librarians are the easiest to operate on. You open them up and everything inside is in alphabetical order.” The Third said, “I like to operate on electricians. You open them up and everything inside is color-coded.” The fourth one said, “I like to operate on lawyers. They’re heartless, spineless, gutless, and their heads and their butts are interchangeable.” Fifth surgeon said, “I like Engineers…they always understand when you have a few parts left over at the end…”
