This repository contains a RISC-V privilege spec 1.11 (WIP) compatible CLINT .
The CLINT plugs into a generic register interface, which may be adapted to various protocols including AMBA APB and AXI 4/Lite (see repository for adapter IPs).
Address | Description | Note |
---|---|---|
BASE + 0x0 |
msip | Machine mode software interrupt (IPI) |
BASE + 0x4000 |
mtimecmp | Machine mode timer compare register for Hart 0 |
BASE + 0xBFF8 |
mtime | Timer register |
To simplify CLINT reconfiguration in your project, you can include the GNU Make fragment clint.mk
in your makefile, for example:
include $(bender path clint)/clint.mk
# Alternative number of cores
CLINTCORES = 4
# Alternative register config template
$(CLINTROOT)/data/clint.hjson.tpl: config/clint.hjson.tpl
cp $< $@
# Rebuild CLINT RTL
all: clint
