32 bit processor core for powering MCUs in embedded takes <10 K gates

Beyond Semiconductor and IP provider CAST have designed low power 32-bit BA21 embedded processor achieving 2.5 CoreMarks, operating up to 125 MHz, and need below 10K logic gates (with a 65nm process). Its two-stage pipelined design offers an opportunity to move from 8-bit MCU to 32-bit in embedded systems applications such as wireless communications or mixed-signal control. “The world’s rush towards big data accessed anywhere requires devices that can capture, process, and analyze information within severe power budgets, and this can only be achieved through highly efficient hardware designs,” said Matjaž Breskvar, chief executive officer of Beyond Semiconductor. “To address such needs, this new BA21 core applies unmatched design efficiency to the most area- and power-sensitive end of the processor spectrum, doing more work in less silicon and using less energy than any comparable 8-, 16-, or 32-bit processor. It’s the perfect fit for the next generation of intelligent sensors, deeply embedded devices, or as a helper in complex SoCs.” Cast says "Energy consumption levels for a BA21-based system can be as low or lower than those possible with any competing processor thanks to the small silicon footprint, extreme code density, and lower memory demand of the BA2 instruction set architecture (ISA). Effective power management functions such as clock gating of unused units and...
