Beilai Technology ARMxy Series Industrial ARM Computers cover these commonly used quad-core ARM Cortex-A53 processor models. The BL350 adopts the TI AM6254, the BL360 series uses the i.MX8M Mini processor, and the BL370 is equipped with the RK3562J processor. Below is a detailed comparison of these three classic quad-core Cortex-A53 processors—TI AM6254, NXP i.MX8M Mini, and Rockchip RK3562J—covering key aspects such as architecture, performance, interfaces, and application scenarios.
| Feature | TI AM6254 | NXP i.MX8M Mini | Rockchip RK3562J |
|---|---|---|---|
| CPU Architecture | 4x Cortex-A53 (1.4GHz) + Cortex-M4F (400MHz) | 4x Cortex-A53 (1.8GHz) + Cortex-M4 (400MHz) | 4x Cortex-A53 (1.8GHz) + Cortex-M0 (200MHz) |
| GPU | GCN GPU (OpenGL ES 3.1) | Vivante GC3200 (OpenGL ES 2.0) | Mali-G52 MP2 (OpenGL ES 3.2) |
| NPU | None | None | 1 TOPS (lightweight AI support) |
| Video Codec | 1080p60 H.265/H.264 | 1080p60 H.265/H.264 | 4K30 H.265/H.264 |
| Industrial I/O | CAN-FD + PRU-ICSS | CAN-FD | CAN 2.0B + TSN Ethernet |
| Real-Time Core | M4F (high real-time performance) | M4 (medium real-time) | M0 (basic real-time) |
| Typical Power | <3W | 2–4W | 2–4W |
4x Cortex-A53 + Cortex-M0, where the M0 core provides basic real-time capabilities (weaker than M4/M4F), suitable for simple real-time tasks (e.g., sensor polling).
Limitations of M0 core:
No Floating-Point Unit (FPU), making real-time computation weaker than M4F.
Relies on software optimization for low-latency control.
TI AM6254 (M4F+PRU) > i.MX8M Mini (M4) > RK3562J (M0)
PRU-ICSS (TI-exclusive) supports nanosecond-level response, ideal for demanding scenarios like motor control.
RK3562J’s M0 core is only suitable for non-critical real-time tasks (e.g., data acquisition).
| Scenario | Recommended Processor | Reason |
|---|---|---|
| High Real-Time Industrial Control | TI AM6254 | M4F+PRU-ICSS enables microsecond-level response (e.g., PLCs, servo drives). |
| Medium Real-Time HMI + Multimedia | i.MX8M Mini | M4 core handles UI response, while A53 runs Linux/Android. |
| Lightweight Real-Time + AI Edge Computing | RK3562J | M0 core processes sensor data, while 1 TOPS NPU runs algorithms like face detection. |
| Ultra-Low-Power Gateways | TI AM6254 | <3W power consumption + hardware-level efficiency optimization. |
TI AM6254:
Best for industrial real-time performance, but lacks AI and 4K video capabilities.
i.MX8M Mini:
Balances multimedia and real-time, ideal for automotive and interactive terminals.
RK3562J:
Cost-effective + lightweight AI, but M0 core is only suitable for non-demanding real-time scenarios (note its performance limits).
Selection Recommendations:
Strict real-time control → TI AM6254
Multimedia + medium real-time → i.MX8M Mini
Low-cost AI edge devices → RK3562J (avoid complex real-time tasks)
This structured comparison helps in selecting the right processor based on real-time requirements, multimedia needs, and AI capabilities.
