The document discusses the evolution of 8-bit to 32-bit processors and microcontrollers, emphasizing the advantages of CAST's offerings, particularly the 8051-compatible cores and the new BA2X family of processors. It highlights the need for higher processing power and code density in modern applications, while asserting that CAST provides a cost-effective and efficient alternative for developers. The 8051 remains relevant for many embedded systems, but the flexibility, power, and efficiency of the BA2X family present compelling reasons for migration.

- 6. Migration Dilemma: Switch from 8051 to 32-bit? 8051 is familiar, efficient and affordable, but: Its processing power is marginal for some modern systems Better code density will significantly reduce memory cost, the dominant expense in many chips Software teams would rather avoid writing code for an 8-bit CPU The 8051 is just too slow to transfer or perform computations on the 32- or 64-bit data typical today The data volume of many apps is beyond the 8051’s capabilities More and more systems need to run an OS and use common AHB peripherals Yet 32-bit processors have much bigger requirements: They can use significantly more silicon and power They can be tremendously more expensive, esp. with royalties Slide 6 8051s and Beyond

- 14. A Suggestion: Don’t Believe Us! Get our software tools, compile and simulate your code, and then measure code size and performance on your own (or just ask us). Let us know your process node, libraries, and target frequency and we will work together on area and power characterization. Do the same with the competition (if they are willing).

Editor's Notes
- #5: FSM stands for Finite State Machine, which typically implements the logic that controls the data-path. FSMs are handcrafted (in RTL) and once they are implemented in silicon you can not change them
- #6: Leader in mixed-signal applications like“smart sensors” and “multi-function” housekeeping functions like firmware updates, calibrations, configuration management etc)Logos are just for some of the recognizable brands that are our customers. More than 200 licences.
