“From the BM1385 onwards, we’ll be using full-custom design flow. While full-custom design flow is more work intensive and does have a greater margin of error, it results in greater efficiency, which is where profit can be found,” Smith continued. “It’s difficult to predict the how long our new chip will take to bring to market, but development on our next chip
