WH440 is housing four 64-bit RISC-V app processors, management core, caches, interrupt controller, memory management unit, memory protection unit, Ethernet, UART and connectivity to FPGA.
WH440 features four extension ports (WTM) based on Wavious proprietary WLINK die-to-die interface. Each WTM supports throughputs of up to 56GB/s at low latency. The extension ports enable our customers to add features such as high-speed connectivity (PCIe, SATA, USB, etc) , multimedia (CSI, DSI, etc) memory interface (DDR, LPDDR, HBM, GDDR etc) or co-processors, such as GPU, ML/AI accelerator, ISP etc.
WLP120 contains LPDDR4x/5 memory controller and two channel LPDDR4x/5 PHY to provide connectivity to main DRAM memory.
The SW stack has been developed to boot, train entire system, and runtime manage it. This system is capable to run RTOS and Linux OS.
