RISC-V pioneer SiFive has announced a new family of processor cores, the Core IP 7 Series, which it claims are “the highest performance commercially available RISC-V cores” and which come in hard-real-time, performance, and Linux-capable variants.
“The SiFive Core IP 7 Series represents a major advancement in RISC-V. The 7 Series brings features to market that have been in-demand but unavailable to customers,” claims SiFive’s Jack Kang of his company’s latest launch. “SiFive offers the broadest portfolio of RISC-V Core IP with the most power efficient and highest performance cores. The 7 Series is our latest innovation that will allow designers to achieve higher efficiency by tailoring their core to the characteristics of their domain – from the smallest edge devices to the data center.”
The family starts with the E7 Core IP Series, a two-part 32-bit family with the single-core E76 and quad-core E76-MC both designed for use where hard-real-time operation is a requirement. The S7 Core IP Series is made up of the 64-bit single-core S76 and quad-core S76-MC, which target latency-sensitive applications including enterprise storage, storage compute, radio base stations and the like.
Finally, the 64-bit single-core U74 and four-plus-one-core U74-M4, which uses four U74 application cores and a single S7 monitor core, are designed to run full-featured operating systems including Linux – as the company’s previous U5 Series has proven on the HiFive Unleashed development board. The company has also pledged future variants with eight application cores.
