Imagination Technologies to design RISC-V cores [cnx-software.com]
Now better known for its PowerVR embedded GPUs, Imagination Technologies tried to enter the CPU market by purchasing MIPS Technologies and introducing microAptiv, interAptiv, and proAptiv cores [cnx-software.com] in 2012.
It did not end up well, as the company had to sell its MIPS technology a few years later, and the MIPS architecture is now barely supported [cnx-software.com]. But Imagination is now working on getting back into the CPU space by designing RISC-V cores.
[...] a May 2021 report by the Financial Times [ft.com] claims Imagination expects to invest up to $150m over the next two years to target a fresh push into the processor design market, specifically citing the RISC-V architecture.
