Renesas provides a clear advantage with their new RX100 MCU series by providing critical DSP functionality not found in other entry-level 32-bit MCUs. Unlike competitive M0/M0+ families, the RX111 provides a hardwarebased MAC (multiply/accumulate) and divide capability – offering a huge improvement in design efficiency and performance compared to softwarebased implementations. The RX111 also offers an extensive DSP instruction set and a 32-bit Barrel shifter – also not found in competitive M0/M0+ offerings. The extensive DSP capabilities offered in the RX100 series make it the obvious choice for low-cost, low-power signal-processing applications.
RX111 DSP Advantage
Only entry-level 32-bit family with hardware-based MAC and divide capability*
|Hardware MAC (Multiply/Accumulate)||Yes (48-bit)||No|
|Barrel Shifter||Yes (32-bit)||No|
RX Series Computing Capabilities vs ARM
The RX100 core features 1.56 DMIPS/MHz and 3.08 CoreMark/MHz performance and achieves 50 DMIPS at 32MHz.
Sources: Cortex M Series CoreMark and DMIPS available on www.arm.com. RX200 and RX100 CoreMark estimates are from Renesas with IAR compiler. RL78 and RX600 CoreMark are published on www.coremark.org. DMIPS/MHz are published on all Renesas brochures for RX and RL families.
