On Wednesday, July 25th, SiFive had the pleasure of hosting Girl Geek X at our offices in San Mateo. Girl Geek X is a brilliant organization with the aim of connecting women across companies large and small for the purposes of networking and sharing career advice in the fast-paced tech industry. Over the past 10 years, Girl Geek X has grown from a 400-person dinner hosted by Google to a well-known Bay Area group with a membership base of more than 15,000.
SiFive — Jul 12, 2018
Last week SiFive launched the new E2 Series RISC-V Core IP. The E2 Series represents SiFive’s smallest, most efficient Core IP Series and is targeted specifically for embedded microcontroller designs. One of the reasons it is great for microcontroller applications is because of its extremely small area footprint, just 0.023mm2 in 28nm for the entire E20 Standard Core! Another reason it's great for the embedded market is its configurability. The E2 Series can be configured even smaller than the E20 Standard Core by removing things like the Interrupt Controller and support for the M extension. Another major reason the E2 Series is great for microcontroller applications is its support for the new RISC-V Core Local Interrupt Controller (CLIC) which allows for extremely low latency interrupt operation, hardware preemption, and hardware prioritization of all interrupts. The CLIC specification is a result of collaboration between RISC-V members in the RISC-V Foundation’s Fast Interrupts Technical Group and the draft specification can be found here.
