Yeah I'm begging all RISC-V SoC Makers: Please provide a Software Emulator for your RISC-V SoC! A

Just follow the steps in this article to create your RISC- V Emulator. Some SoC Peripherals might be missing, but a Barebones Emulator is still super helpful for porting, booting and testing any Operating System."

@lupyuen

@lupyuen So true. Honestly, I think there should at least be a minimal emulator for every SoC. It helps a lot with operating system development.

@lupyuen maybe I should persuade all SoCs with PCIe to implement PCIe-CPU coherency (because currently Linux in-tree GPU drivers require it)

SWIPT: Long-Range Wireless Power Transfer for Moving Wireless Devices

mdpi.com/2079-9292/13/13/2550

Long-Range Wireless Power Transfer for Moving Wireless IoT Devices

Wireless technologies are revolutionizing communications, with recent deployments, such as 5G, playing a key role in the future of the Internet of Things (IoT). Such progress is leading to an increasingly higher number of wirelessly connected devices. These require increased battery use and maintenance, consequently straining current powering solutions. Since most wireless systems rely on radiofrequency (RF) waves for communications and feature low-power technologies, it is increasingly feasible to develop and implement wireless power transfer solutions supported by RF. In this paper, a simultaneous wireless information and power transfer (SWIPT) solution targeting small mobile devices is presented. This solution uses beamforming to mitigate the path loss associated with the RF power propagation. It relies on an RF backscattering tracking algorithm to power moving devices. The feasibility to power wearable devices is demonstrated by tracking a walking individual (approximately 5 km/h) at a distance of 0.5 m while transferring a minimum of 6 dBm to a wearable device using 2 GHz RF signals. Simulations were used to determine the viability of such a solution to deliver useful power levels to a 1.2 × 1.4 m2 working area without exceeding specific absorption rate (SAR) limits.
