EnSilica launches eSi-3260 processor core with comprehensive SIMD DSP extensions targeting IoT sensing nodes and always-on applications
Combines advanced DSP features with eSi-RISC’s characteristic low power and
small silicon footprint
Wokingham, UK – 14th April 2015. EnSilica, a leading independent provider of semiconductor IP and services, has added to its family of eSi-RISC processor cores with the launch of the eSi-3260 targeted at IoT sensing nodes and always-on applications. The eSi-3260 combines advanced DSP functionality with the characteristic eSi-RISC small footprint and extremely low power consumption.
The inclusion of a 64-bit precision, fully-pipelined MAC unit makes the eSi-3260 ideal for audio, high accuracy sensor hub, motion control and touch screen applications. In addition to 32-bit data, the MAC unit supports dual 16-bit SIMD (single instruction multiple data) multiply and MAC operations. Uniquely, full complex multiplication is also supported, performing four multiplies and two additions per cycle. The inclusion of saturating and rounding arithmetic, along with instructions to support bit-reversed addressing, provides
excellent FFT acceleration and accuracy.
The eSi-3260 employs a 5-stage pipeline which has been optimized to deliver market-leading performance in mainstream process nodes with frequencies of over 1GHz obtainable in a 28nm process with dynamic power as low as 14μW/MHz. This can be reduced to 3μW/MHz when optimizing the processor for power, rather than frequency. A flexible memory architecture, with either native, AXI or AHB interfaces, allows the inclusion of instruction and data caches as well as tightly coupled memories for running code that is timing critical. The addition of a cache facilitates high-performance operations even when they are run from embedded Flash.
The radix-8 fast divide and square root options enable 32-bit integer division and square root operations to be reduced to six cycles, greatly decreasing the cycle count in sensing operations where these operations are key to the code operation. An optional, fully pipelined single precision floating point capability helps accelerate high dynamic range calculations for applications such as gesture recognition and fingerprint detection. Custom instruction support allows a further level of application acceleration such as IIR and logarithmic DSP operations or cryptographic operations for standards including ECC, RSA, AES and SHA.
“The balance of processing performance, silicon area, low power and DSP functionality provided by the eSi-3260 delivers a distinct technology edge for customers looking to develop complex IoT sensing nodes and devices in what is a highly competitive market,” said Ian Lankshear, CEO of EnSilica.
Adopting the eSi-RISC series of processors for its touch screen controllers, Ken Tsui, Vice President, Design Engineering of Solomon Systech Limited said: “The solution developed by EnSilica, with its excellent features, has enhanced greatly the functionality of our product. We look forward to joining hands again with the team to develop more high-performance IC solutions.”
