I thought this was about a new kind of bignum acceleration, which has been a thing in some embedded systems for more than a decade. NXP had one on an el-cheapo SoC product already back in 2008-2009. But no, this is apparently a generic ECC acceleration unit. It's still a bignum system but a somewhat more focused one. I would love to see some comparative benchmarks - not only on speed, but also on driver implementation complexity.
