"The PCIe support makes it easier to build a fully configured RISC-V PC, such as a 'Linux development workstation"
"For the architecture to really take off, it’s products like these that are required, products that encourage and simply software development."
"The HiFive Unleashed Expansion Board and HiFive Unleashed allow designers to develop complete Linux applications on a modern RISC-V CPU running at 1 GHz+."
"The HiFive Unleashed Expansion Board allows developers to implement custom peripherals in the on-board PolarFire field programmable gate array (FPGA)."
"Microsemi and SiFive Launch HiFive Unleashed Expansion Board, Enabling Linux Software and Firmware Developers to Build RISC-V PCs for the First Time"
"For developers, this looks to be an ideal solution for application design, testing, and implementation."
"Proporcionando conectores para almacenamiento y de E/S, esta tarjeta de expansión para placa RISC-V/Linux facilita la construcción de un completo sistema informático con la placa base a la que complementa."
At its core, the HiFive Unleashed Expansion Board adds PCIe root port capability to the HiFive Unleashed board, enabling you to create a RISC-V PC. Use it to add HDD’s, SSDs, audio cards, network adapters, and/or graphics cards. You can port your linux distro to this platform along with all of your favorite packages. Accelerate software development with an out-of-the-box solution.
The board is 10.7" long by 4.62" wide. It comes with a power supply, USB cable, and a FlashPro4 FPGA programmer.
The board comes pre-programmed with a chiplink to PCIe Root Port bridge enabling easy connectivity to PCIe add in cards. The board also has additional expansion capabilities for bit streams yet to come.
Included with the purchase of the kit is a free, one year Libero GOLD License ($995 value). Initially, the kit will include only a fixed bitstream that can enable a PCIe Root Complex. In the future, we will open up the kit to other solutions. At that time, developers can take advantage of the Libero license. Sign up for updates to stay informed.
As you can see from the block diagram, there is more to this board than just adding PCIe to the [HiFive Unleashed Board] (https://www.crowdsupply.com/sifive/hifive-unleashed). Sign up to be notified of future FPGA bitstream upgrades that enable more functionality for you.
The board measures approximately 10.7” x 4.62.”
Here’s a cool picture of the layout. Connect an M.2 SSD drive on the backside for fast storage.
