Slide 6 8051s and Beyond

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

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).
