IPs

• RaveNoC: Configurable Network-on-Chip described in SystemVerilog.
• NoX: Soft-core RISC-V RV32I with AMBA compatible interfaces and FreeRTOS port.
• DMA: DMA engine based on AMBA AXI protocol, fully configurable.
• Skid Buffer: Skid buffer is to break the combinatorial path between the sender and receiver interfaces, also known as register slices (AMBA convention).
• Simple interrupt controller: Generic interrupt controller with configurable fifo size and fixed priority.
• SPI Master: AXI SPI design with programmable FIFO buffer size and external IOs.
• M-TIMER RISC-V: Simple machine timer design fully compatible with privileged RISC-V specification.
• Reset controller: Reset controller used to define start vector value for general purpose CPUs and software controllable reset output.
• Synchronous general-purpose FIFO: Synchronous FIFO design.
• Asynchronous general-purpose FIFO: Asynchronous FIFO design.
• CDC 2-FF: General clock-crossing 2FF design.
• AXI ROM wrapper: General ROM wrapper design for auto-generated images.
