A public technical article edition tracing the evolution of ARM Cortex-A processors in industrial computing products, featuring EBYTE's full series of core boards, single board computers and industrial PCs, from single-core to octa-core architectures, with future trend predictions.
Introduction: The Core Driver of Industrial Computing
Driven by the waves of industrial IoT, edge computing, AI vision and smart manufacturing, industrial computing products are undergoing a profound transformation from "single/dual-core" to "multi-core heterogeneous" architectures. ARM Cortex-A series processors, as the mainstay of industrial-grade embedded systems, clearly reflect the eternal pursuit of higher performance, lower power consumption and stronger AI computing power in industrial computing.
This article reviews the evolution of ARM Cortex-A processors from single-core to octa-core, combined with EBYTE's full series of core boards, single board computers (SBCs) and industrial PCs, and predicts future technology trends.
Which User Pain Points Are Solved?
The analysis of multi-core processor development trends mainly serves the following four core user groups, precisely addressing their rigid requirements:
| User Group | Typical Role | Core Pain Point | How Trends Solve It |
|---|---|---|---|
| Embedded system architects | Hardware engineers, project managers | Need to choose processor architectures with foresight so products don't become outdated in 3-5 years, while balancing performance, power and cost | Understanding multi-core processor trends enables early product roadmap planning and selection of the most competitive processor platforms |
| Industrial automation solution providers | System integrators, PLC engineers | Need high-performance edge computing platforms running HMI, data acquisition, AI inference and more simultaneously; traditional single-core processors fall short | Multi-core processors run tasks in parallel: one core for HMI, one for data acquisition, one for AI inference — no mutual interference |
| IoT gateway developers | IoT solution providers, system integrators | Need edge gateways with local AI inference while processing large amounts of sensor data; computing requirements keep rising | From quad-core to octa-core, processors with integrated NPUs become mainstream, providing ample compute for edge AI inference |
| AI edge computing practitioners | AI algorithm engineers, system architects | Need to run more complex AI models locally (YOLOv5, ResNet), demanding higher compute and lower latency | Processors evolve from 1 TOPS NPU to 2 TOPS NPU and beyond, continuously improving edge AI inference capability |
Evolution of Multi-Core ARM Cortex-A Processors
Single-Core Era: Low-Cost, High-Reliability Entry-Level Choice
Representative architecture: ARM Cortex-A7 (32-bit)
Core products: NXP i.MX6ULL, Allwinner T113-S3
Typical product: EBYTE ECK20-6Y28C (i.MX6ULL)
Technical features:
Clock range: 792MHz ~ 1.2GHz
Core advantages: extreme cost-performance, ultra-low power, mature Linux ecosystem
Typical applications: low-cost PLCs, HMIs, IoT gateways, data acquisition terminals
Trend analysis: Single-core Cortex-A7 processors remained the mainstream choice for low-cost industrial control until around 2025. However, as edge computing and AI demands grow, their processing capability has gradually become a bottleneck — especially in scenarios requiring multiple simultaneous tasks or graphical interfaces.
Dual-Core Era: Performance Improvement and China-Made Substitution
Representative architecture: ARM Cortex-A7 (32-bit) dual-core
Representative products: Allwinner T113-i, T113-S3
Typical products: EBYTE ECK30-T13IA, ECK31-T13SA
Technical features:
Clock range: 1.2GHz
Core advantages: heterogeneous dual-core (Cortex-A7 + RISC-V + DSP), significantly improved performance, fully China-made design
Typical applications: IoT gateways, HMI, smart cities, edge computing
Trend analysis: Dual-core processors mark the leap from "good enough" to "great to use". In the Allwinner T113 series, the addition of RISC-V and HiFi4 DSP demonstrates the potential of heterogeneous multi-core architectures, laying the foundation for higher-performance processors.
Quad-Core Era: Fusion of High Performance and AI Computing Power
Representative architecture: ARM Cortex-A55 (64-bit) / Cortex-A53 (64-bit)
Representative products: Rockchip RK3562, RK3568
Typical product: EBYTE ECK40-E (RK3562)
Technical features:
Clock range: 2.0GHz
Core advantages: quad-core 64-bit architecture, integrated 1 TOPS NPU, AI inference support, performance leap
Typical applications: edge AI computing, industrial vision, smart terminals, high-performance HMI
Trend analysis: The emergence of quad-core processors marks the official entry of industrial computing into the AI era. With 1 TOPS NPU compute, devices can run lightweight AI models locally with millisecond-level response. The leap from 32-bit to 64-bit also means support for larger memory and more complex applications.
Octa-Core Era: Ultimate Performance and AI Flagship
Representative architecture: ARM Cortex-A55 (64-bit) octa-core
Representative product: Allwinner T527
Typical product: EBYTE ECB32-PB series (single board computer)

Typical applications: edge AI computing, self-service terminals, digital signage, smart manufacturing, robotics
Trend analysis: Octa-core processors represent the current highest performance level of industrial-grade ARM processors. With 2 TOPS NPU compute, more complex AI models such as YOLOv5 and MobileNetV3 can run. Powerful video processing makes them excellent for digital signage, video surveillance and similar applications.
Summary of Core Development Trends
Trend 1: From Single-Core to Multi-Core, Continuously Improving Parallel Processing
| Era | Core Count | Typical Architecture | Representative Product | Typical Applications | Core Advantage |
|---|---|---|---|---|---|
| Single-core era | 1 | Cortex-A7 | ECK20-6Y28C (i.MX6ULL) | Low-cost PLC, HMI | Extreme cost-performance, low power |

Trend 2: From General Computing to AI Heterogeneous Computing — NPU Becomes Standard
Early stage: Processors relied only on the CPU for general computing; AI inference depended on the cloud.
Middle stage: Integrated DSPs (e.g. HiFi4) and GPUs assisted AI computing, but with limited efficiency.
Now: Integrated dedicated NPUs (Neural Processing Units) have become mainstream, such as the RK3562's 1 TOPS NPU and the T527's 2 TOPS NPU. NPUs are designed specifically for AI inference, delivering efficient compute at low power.
Future: NPU compute will continue to increase, supporting more precisions (e.g. INT4, INT8) and enabling more complex AI models — including Transformer architectures — to run at the edge.
Trend 3: From 32-Bit to 64-Bit, Supporting Larger Memory and More Complex Applications
32-bit era (ARMv7-A): Supports up to 4GB memory, suitable for lightweight Linux applications.
64-bit era (ARMv8-A/v8.2-A): Supports 8GB or even more memory, providing ample headroom for complex applications such as AI models, databases and containerized applications.
Trend 4: From Imported to China-Made
Early stage: The NXP i.MX6ULL (imported) was the mainstream choice with a mature ecosystem but relatively high cost.
Now: China-made processors such as the Allwinner T113 series and Rockchip RK series have become mainstream. They offer stronger performance, lower cost and secure, controllable supply chains, meeting China-made substitution requirements.
Future: China-made processors will further expand their product lines, covering everything from entry-level to flagship application scenarios.
