It seems like a really strange choice to me that they made the arm and riscv cores mutually exclusive in each core complex since this just wastes die space on the core you're not using which in turn drives up the cost.<p>I feel like it would've been preferable if they either went all in on riscv or at least made it so all 4 cores could be used at the same time.<p>But if I were to guess the performance of the riscv cores probably doesn't match the ARM cores so they weren't confident enough in shipping a pure riscv SoC like espressif does.<p>Any other guesses as to why they might've gone this route?
