RISC-V RV64IS-compatible processor for the Kestrel-3

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
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 chapter of the KCP53000's datasheet.
