Abstract: A circuit includes: a parallel data interface; and transition control circuitry coupled to the parallel data interface. The transition control circuitry is configured to: receive an input bit stream sample; determine a bit transformation pattern for the input bit stream sample in accordance with a target criteria; and generate an output bit stream symbol from the input bit stream sample and the bit transformation pattern, wherein the output bit stream symbol has more bits than the input bit stream sample.

Abstract: A one-time write, read-only memory for storing trimming parameters includes an address pointer table, a fixed packet portion, and a flexible packet portion. The fixed packet portion includes one or more fixed packets, each fixed packet including trimming parameters for a component identified for trimming during a design phase. The flexible packet portion includes one or more flexible packets of different types. Each flexible packet includes trimming parameters for a component identified for trimming after the design phase. One packet type includes a length section and a number of fields equal to a value stored in the length section. Each field includes an address, a trimming parameter, and a mask. Another packet type includes trimming parameters associated with operands in operating instructions for a microcontroller, where the operands include an address and a mask.
