+We seek investors, sponsors (whose contributions thanks to NLNet may be
+tax-deductible), engineers and potential customers, who are
interested, as a first product, in the creation and use of an entirely
libre low-power mobile class system-on-a-chip. Comparative benchmark
performance, pincount and price is the Allwinner A64, except that the
We can look at larger higher-power ASICs either later or, if funding
is made available, immediately.
-Recent applications (Oct 2019) are for a test chip in 180nm, 64 bit, single core dual issue, around 300 to 350mhz. This will provide the confidence to go to higher geometries, as well as be a commercially viable embedded product in its own right.
