Elevating Your SoC for Reconfigurable Computing – EFLX® eFPGA and InferX™ DSP and AI

Field-Programmable Gate Arrays (FPGAs) have long been celebrated for their unmatched flexibility and programmability compared to Application-Specific Integrated Circuits (ASICs). And the introduction of Embedded FPGAs (eFPGAs) took these advantages to new heights. eFPGAs offer on-the-fly reconfiguration capabilities, allowing system designers to adapt to evolving protocols and cryptographic standards without the need for costly hardware changes. This inherent flexibility not only reduces risk but also ensures longevity and scalability, essential factors in today’s fast-paced technological landscape.

Flex Logix is well known for its reconfigurable computing solutions, particularly embedded Field-Programmable Gate Arrays (eFPGAs). What may not be as well-known is the company’s signal processing IP. As Artificial Intelligence (AI) applications continue to proliferate across industries, the need for making asynchronous decisions has become increasingly imperative. These applications demand robust support for linear math operations, convolution, and transforms, all of which require a powerful signal processing engine. To address this need, FlexLogix offers signal processing IP as well. By combining eFPGAs with dedicated signal processing capabilities, designers can develop more efficient solutions that preempt the signal processing engine’s starvation due to memory bandwidth limitations. This integration not only enhances performance but also unlocks new possibilities for real-time processing and analysis in AI applications. This was the focus of a talk by Jayson Bethurem, VP of Marketing at FlexLogix, at the IPSoC 2024 Silicon Valley conference.

eFPGAs and Asynchronous Applications

eFPGAs present a versatile solution for asynchronous applications, operating without a global clock signal and relying on local timing mechanisms. One key advantage of eFPGAs in this domain is their ability to offer custom timing control, allowing designers to implement precise timing circuits and control mechanisms tailored to the specific requirements of asynchronous applications. This flexibility enables optimization of timing parameters such as delay, skew, and signal propagation independently for different parts of the circuit, ensuring efficient operation.

Moreover, eFPGAs facilitate the implementation of fine-grained synchronization techniques, such as handshake protocols and delay-insensitive circuits, commonly used in asynchronous design methodologies. These synchronization mechanisms ensure correct operation and data integrity in asynchronous systems, even in the presence of varying delays and timing uncertainties. Additionally, eFPGAs provide high-speed interconnect resources that can be customized to build efficient communication channels between asynchronous modules or data processing elements, enhancing the performance and scalability of asynchronous systems. With support for dynamic reconfiguration, power efficiency features, and fault tolerance mechanisms, eFPGAs serve as an attractive platform for developing efficient and reliable asynchronous systems across various domains.

Signal Processing in eFPGA Use Cases

eFPGAs enable customizable accelerators for algorithms in machine learning and signal processing. Additionally, eFPGAs handle protocol offloading in communication systems, reconfigurable I/O interfaces in consumer electronics, and real-time data processing in storage and communication devices. They also support firmware upgrades in embedded systems and dynamic resource allocation in high performance computing (HPC). In automotive and industrial automation, eFPGAs facilitate sensor fusion and real-time image processing. They enable customizable networking protocols, enhance security features, and ensure fault tolerance in critical systems.

Summary

eFPGA integration streamlines product development by minimizing mask spins, reducing engineering costs, and accelerating time-to-market. Their adaptability ensures longevity by accommodating evolving protocols and facilitating periodic bug fixes through firmware updates, thus averting costly recalls. They enable product differentiation by implementing unique features, attract customers, and support premium pricing. Moreover, they meet regional requirements, address security threats, and streamline testing and debugging processes, further enhancing efficiency. Lastly, eFPGA integration supports the integration of evolving IP cores (such as in the field of AI), ensuring products remain competitive with the latest technological advancements without requiring hardware upgrades.
