- MichaelZuo 3y ago> If it requires any initialisation itself, it must be handled by a hardcoded state machine in the RTL logic. Thanks, that's what I was trying to ask about. How does the 'hardcoded state machine in the RTL logic' in the SBE execute the very first instruction?
- hlandau 3y agoThe SBE is a processor. It fetches instructions and executes them, starting from a reset vector. That reset vector is the OTPROM.
- MichaelZuo 3y agoTo clarify, I'm asking about how the 'hardcoded state machine' functions at the beginning of boot-up, not of the overall SBE that is initialized later.
