Benefits of technology

This technology described in this patents allows an integrated chip (IC) card or smartcard device to operate at different speeds depending upon user preferences. By embedding programming into these memories, the IC card's operation becomes faster due to fewer cycles needed during execution. Additionally, the system includes features like error detection mechanisms, support for both hardwired and softwire interfaces, and simplified interface designs. Overall, this innovative approach simplifies the hardware architecture while maintaining efficiency and performance.

Problems solved by technology

Technics Problem addressed in this patents include improving the efficiency and flexibility of embedding memory into computer programs without requiring extensive modifications during development cycles due to the lengthy process required for generating them. Additionally, current techniques require significant effort from developers who want to rewrite code rather quickly because they may lack speed capabilities. Therefore, new generations of built-in RAM cores were developed which allow users to easily modify certain aspects of the hardware configuration through external interfaces like USB tokens.
