4. Why Now?
8051s aren’t dead
Still cost-effective for simple mixed-signal
They set the standard for value
But, customer needs are changing
Many applications need more complex processing
Example of a market in flux: Automotive
Example of big product advancements: Displays

9. BA22 Code Density
CSiBE Comparison
BA2 Instruction set
outperforms
competition
Code size includes
some data, so
actual difference
is smaller
BA22 Customer Comparisons
Code density up to 20% better than ARM Thumb-2
Much better than full ARM, PPC, and MIPS

19. A suggestion: Don’t believe us!
Get our software tools, and development kits;
compile and simulate your code and then
measure code-size and performance on your
own; ask us to help you get started
Let us know of your process
node, libraries, and target frequency and we
will work together on area and power
characterization
