BLIIoT’s ARMxy series of industrial computers cover several mainstream Cortex-A53 processors. Among them:
BL350 adopts the TI AM6254,
BL360 series is built on the NXP i.MX8M Mini,
BL370 is powered by the Rockchip RK3562J.
Below is a detailed comparison of three classic quad-core Cortex-A53 processors—TI AM6254, NXP i.MX8M Mini, and Rockchip RK3562J—covering architecture, performance, interfaces, and application suitability.
| Feature | TI AM6254 | NXP i.MX8M Mini | Rockchip RK3562J |
|---|---|---|---|
| CPU | 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/F | CAN-FD + PRU-ICSS | CAN-FD | CAN 2.0B + TSN Ethernet |
| Real-Time Core | M4F (strong real-time) | M4 (medium real-time) | M0 (basic real-time) |
| Typical Power | <3W | 2–4W | 2–4W |
RK3562J Architecture:
No Floating Point Unit (FPU), real-time capability is lower than M4F.
Relies on software optimization for low-latency control.
4x Cortex-A53 + Cortex-M0: the M0 core only provides basic real-time handling (weaker than M4/M4F), suitable for simple real-time tasks such as sensor polling.
Real-Time Performance Ranking:
TI AM6254 (M4F + PRU) > i.MX8M Mini (M4) > RK3562J (M0)
PRU-ICSS (TI proprietary) enables nanosecond-level response, ideal for demanding scenarios such as 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 delivers microsecond-level response (PLC, servo drive). |
| Medium Real-Time HMI + Multimedia | i.MX8M Mini | M4 handles UI responsiveness while A53 runs Linux/Android. |
| Light Real-Time + Edge AI | RK3562J | M0 processes sensor data, 1 TOPS NPU runs AI inference such as face detection. |
| Ultra-Low Power Gateway | TI AM6254 | <3W power + hardware-level efficiency. |
TI AM6254:
Benchmark for industrial real-time performance but lacks AI and 4K video capability.
NXP i.MX8M Mini:
Balanced between multimedia and real-time, well-suited for automotive and interactive terminals.
Rockchip RK3562J:
Cost-effective + lightweight AI support; M0 core is limited to non-demanding real-time use (users should be aware of its performance boundaries).
Selection Guide:
For strict real-time control → TI AM6254
For multimedia + medium real-time → i.MX8M Mini
For low-cost AI edge devices → RK3562J (avoid complex real-time tasks)
