There are many processor architectures that have different instruction memories for different functional units.
SoCs often have multiple functional units on the same die. For radios that allows for a pipeline. You can limit what an EPROM will accept with a crypto signature. This is common stuff. -----Original Message----- From: "David Lang" <[email protected]> Sent: Mon, Mar 14, 2016 at 3:04 pm To: [email protected] Cc: "Wayne Workman" <[email protected]>, "bufferbloat-fcc-discuss" <[email protected]>, [email protected], [email protected] Subject: Re: [Make-wifi-fast] [bufferbloat-fcc-discuss] [Cerowrt-devel]arstechnica confirmstp-link router lockdown On Mon, 14 Mar 2016, [email protected] wrote: > An external "limit-exceeding signal detector" could also be very inexpensive, > if it did not need to do ADC from the transmitted signal, but could get > access > to the digital samples and do a simple power measurement. I agree with this, but have concerns about how you can lock down part of the firmware and not all of it. You still have the problem of telling the chip/algorithm which set of rules to enforce, and updating it when the requirements change.
