    Abstract: A device for transmitting a signal over a serial link includes a transmission processor to carry out, before transmission over the serial link, a scrambling process on successive initial packets of the signal to form a scrambled packet for each initial packet. The transmission processor includes an encoding circuit to carry out an encoding process on each initial packet to deliver an encoded packet. The encoding process includes, for each current initial packet starting from the second, encoding of the current initial packet with the preceding scrambled packet. Calculation circuitry determines, for each initial packet, a bit disparity of the encoded packet and determination of a cumulative bit disparity. Comparison circuitry carries out a comparison process involving the bit disparity of the encoded packet and the cumulative disparity, with the scrambled packet being the encoded packet or the inverted encoded packet, depending on the result of the comparison process.

    Abstract: Embodiments disclosed herein generally relate for efficiently retrieving boot code for a processor from serial NOR flash memory. When a boot code request is received, a request handler in data capture logic tags successive address read requests to indicate whether the requests indicate contiguous addresses in the NOR flash memory for the boot code. Different circuitry in the data capture logic operates on different mesochronous clock signals. One clock signal drives the capture of boot code from NOR flash, and the other controls synchronized tagging, storing, pre-fetching, and transmitting of the captured boot code data.
