Flexible Processor Cores And Popular RTOS Combine To Target Demanding IoT Apps


EnSilica and Express Logic have collaborated to port Express Logic’s popular ThreadX real-time operating system (RTOS) to EnSilica’s eSi-RISC family of silicon-proven, highly-configurable embedded processor cores. The combination is capable of addressing the most demanding IoT and industrial applications.

The combination of eSi-RISC and ThreadX helps today’s embedded developers who are challenged to provide solutions that process high volumes of complex data using minimal processor cycles and memory. EnSilica’s flexible eSi-RISC processor cores and ThreadX’s highly efficient ThreadX RTOS create a commercial-grade solution capable of addressing the most demanding projects now and into the future, says the company.

ThreadX features efficient real-time responsiveness and code compactness that appeal to developers of the most demanding, deeply embedded consumer and industrial electronics. ThreadX ease-of-use is facilitated by its intuitive, highly functional API and advanced, instant-on RTOS features.


The small footprint, high-performance, and low-power characteristics, when combined with ThreadX’s pre-certification for many safety standards, make the combination suitable for IoT and industrial applications.

EnSilica’s eSi-RISC is a family of highly configurable and low-power soft processor cores for embedded systems that scale across a wide range of applications and uniquely support both 16-bit and 32-bit configurations. The cores have been extensively silicon proven in a variety of ASIC technologies down to 28nm.

The eSi-RISC family includes the eSi-1600 16-bit processor, eSi-3200 32-bit processor, eSI-3250 32-bit processor, eSi-3250sfp incorporating a single precision floating point processor, eSi-3260 32 bit processor with SIMD DSP extensions and eSI-32X0MP 32-bit scalable, asymmetric multicore processor. The processor cores also benefit from a configurable memory architecture and configurable cache options.

Single Software Platform Unifies More Than 150 TI Processors

The company says that a commercially supported RTOS is more preferable for successful embedded product development and fast time-to-market delivery. The combination of ThreadX and eSi-RISC delivers unrivalled compactness, high performance and low-power for all manner of embedded applications.
