microwatt VS vISA

My favorite part of this project is the pretty large battery of test cases. A lot of chip rtl releases don't bother with open sourcing the verification too, and that's arguably more useful than the rtl in the first place.

MicroWatt is the only one I know of.

I have several OpenPOWER systems, including the POWER9 I use as my usual desktop. Besides IBM and other server manufacturers like Tyan and Wistron, you can get them as Raptor workstations and servers.

If you want an OpenPOWER design to play with, look at Microwatt ( https://github.com/antonblanchard/microwatt ) which is complete enough to boot Linux.

Not true, as of 2019 the power ISA is able to be used without needing to pay any royalties to ibm under the openpower foundation. There's already a few projects that have taken advantage of it such as libreSOC and Microwatt. Source code for various firmware components are also freely available pertaining to the power platform.

https://github.com/antonblanchard/microwatt is an example of a Linux-capable 64-bit core that has been submitted on multiple Open MPW shuttles:

At the other end of the scale, if anyone wants to play you can run a little openpower CPU on a FPGA with completely open source. https://github.com/antonblanchard/microwatt

It's capable of running Linux, some example docs are https://shenki.github.io/boot-linux-on-microwatt/

Why dismiss POWER or SPARC ? :-)

Speed test against my six lines of verilog cpu when? *

* Only six lines of verilog if one only uses FPGA LUTs as Ram.

Well, I made a CPU Instruction Set Architecture called Bit-Bit-Jump that can simulate Bit-Bit-Jump Machine Code at approximately 5.6 Megahertz here: https://gitlab.com/VitalMixofNutrients/vISA

Hello. Over the past six months, I have been working on a CPU ISA named Bit-Bit-Jump. Suprisingly, it is actually the world's simplest CPU ISA, comprising only SIX lines of Verilog code.

You're right, it doesn't look like an actual binary.. How can I turn it into an actual binary?

Well, the simplest ISA is six lines of Verilog and it's called Bit-Bit-Jump

Idea: Because I don't have the money for Vivado (Free version is limited to a few thousand lines of Verilog) / Quartus (Free version won't let me perform DPR), it would be awesome if you could find a way to implement my Bit-Bit-Jump Soft-Core into your project.
