ARC EM DSP supports Always-on DevicesSemiWiki - Eric EsteveJun. 23, 2014 |
The ARC EM family is the low-power, embedded and low footprint processor part of the larger ARC processor. To target the ultra low-power markets like wearable and IoT, Synopsys has added DSP capabilities to EM5D and EM7D. To be specific, these cores are optimized for ultra low-power control and DSP, thanks to:
- Energy-efficient 3-stage RISC pipeline
- Unified single cycle 32x32 MUL/MAC unit
- Energy-efficient signal processing of voice/speech, audio and sensor data
- Operating Floating Point Unit (FPU)
Thus, the EM5D and EM7D cores are especially suited to always-on voice activated and sensor processing applications. The dynamic power consumption of the ARC EM processors can be as low as 3 uW/MHz, particularly well-suited for wearable devices and battery powered applications.
