Nuvacore, a CPU startup founded by legendary architects Gerard Williams, John Bruno, and Ram Srinivasan, is taking an unconventional approach by designing its WarpCore processor's core IP independent of a specific instruction set architecture, deferring ISA selection until later in development. This Core First strategy allows the team to optimize the microarchitecture for performance and power efficiency in AI and data center applications before committing to an ISA like Arm, RISC-V, or x86.
