# The KCP53000 Core Family (formerly Polaris)

Polaris used to be the name of a simple, 64-bit RISC-V ISA CPU.
However, before I could actually complete the project,
I discovered that AMD had a line of GPUs by that name.

So, I've decided to rename the Polaris CPU to something deliberately not trademarkable: KCP53000.
In so doing, I've also decided that there ought to be a family of useful modules built to work with this CPU.
Just as one considers the "m68K" a complete *family* of products built around the Motorola 68000 (and later, CPU32) ISA,
so too should people regard the KCP53000 as the first member of a *family* of KCP53K ("53K") cores.

The following cores exist so far in this repository:

|ID|Subdirectory|Description|Datasheet?|
|:-:|:-:|:--|:-:|
|KCP53000|processor|64-bit processor built on the RISC-V 64-bit integer instruction set.|[Yes](processor/docs/SUMMARY.md)|
|KCP53001|arbiter|64-bit Furcula interconnect arbiter.|Not yet (note 1)|
|KCP53002|wb-bridge|64-bit Wishbone interconnect bridge.|Not yet (note 1)|
|KCP53003|bottleneck|64-bit to 16-bit Furcula bridge.|Not yet|

**Notes**

1. A prototype of these cores are documented in the [Example Application](processor/docs/example.md) chapter of the KCP53000's datasheet.
