Versal® adaptive compute acceleration platforms (ACAPs) combine Scalar Engines, Adaptable Engines, and Intelligent Engines with leading-edge memory and interfacing technologies to deliver powerful heterogeneous acceleration for any application. Most importantly, Versal ACAP hardware and software are targeted for programming and optimization by data scientists and software and hardware developers. Versal ACAPs are enabled by a host of tools, software, libraries, IP, middleware, and frameworks to enable all industry-standard design flows.

Built on the TSMC 7 nm FinFET process technology, the Versal portfolio is the first platform to combine software programmability and domain-specific hardware acceleration with the adaptability necessary to meet today's rapid pace of innovation. The portfolio includes six series of devices uniquely architected to deliver scalability and AI inference capabilities for a host of applications across different markets—from cloud—to networking—to wireless communications—to edge computing and endpoints.

The Versal architecture combines different engine types with a wealth of connectivity and communication capability and a network on chip (NoC) to enable seamless memory-mapped access to the full height and width of the device. Intelligent Engines are SIMD VLIW AI Engines for adaptive inference and advanced signal processing compute, and DSP Engines for fixed point, floating point, and complex MAC operations. Adaptable Engines are a combination of programmable logic blocks and memory, architected for high-compute density. Scalar Engines, including Arm® Cortex®-A72 and Cortex-R5F processors, allow for intensive compute tasks.

The Versal AI Edge series focuses on AI performance per watt for real-time systems in automated drive, predictive factory and healthcare systems, multi-mission payloads in aerospace & defense, and a breadth of other applications. More than just AI, the Versal AI Edge series accelerates the whole application from sensor to AI to real-time control, all with the highest levels of safety and security to meet critical standards such as ISO26262 and IEC 61508.

The Versal AI Core series delivers breakthrough AI inference acceleration with AI Engines that deliver over 100x greater compute performance than current server-class of CPUs. This series is designed for a breadth of applications, including cloud for dynamic workloads and network for massive bandwidth, all while delivering advanced safety and security features. AI and data scientists, as well as software and hardware developers, can all take advantage of the high-compute density to accelerate the performance of any application.
