Introduction
i.MX 6DualPlus/6QuadPlus Automotive Applications Processors, Rev. 3, 11/2018
NXP Semiconductors 7
— Two Watchdog timers (WDOG)
— Audio MUX (AUDMUX)
— MLB (MediaLB) provides interface to MOST Networks (150 Mbps)
The i.MX 6DualPlus/6QuadPlus processors integrate advanced power management unit and controllers:
• Provide PMU, including LDO supplies, for on-chip resources
• Use Temperature Sensor for monitoring the die temperature
• Support DVFS techniques for low power modes
• Use Software State Retention and Power Gating for Arm and MPE
• Support various levels of system power modes
• Use flexible clock gating control scheme
The i.MX 6DualPlus/6QuadPlus processors use dedicated hardware accelerators to meet the targeted
multimedia performance. The use of hardware accelerators is a key factor in obtaining high performance
at low power consumption numbers, while having the CPU core relatively free for performing other tasks.
The i.MX 6DualPlus/6QuadPlus processors incorporate the following hardware accelerators:
• VPU—Video Processing Unit
• IPUv3H—Image Processing Unit version 3H (2 IPUs)
• GPU3Dv6—3D Graphics Processing Unit (OpenGL ES 3.0) version 6
• GPU2Dv3—2D Graphics Processing Unit (BitBlt) version 3
• GPUVG—OpenVG 1.1 Graphics Processing Unit
• 4 x PRE—Prefetch and Resolve Engine
• 2 x PRG—Prefetch and Resolve Gasket
• ASRC—Asynchronous Sample Rate Converter
Security functions are enabled and accelerated by the following hardware:
• Arm TrustZone including the TZ architecture (separation of interrupts, memory mapping, etc.)
• SJC—System JTAG Controller. Protecting JTAG from debug port attacks by regulating or blocking
the access to the system debug features.
• CAAM—Cryptographic Acceleration and Assurance Module, containing 16 KB secure RAM and
True and Pseudo Random Number Generator (NIST certified)
• SNVS—Secure Non-Volatile Storage, including Secure Real Time Clock
• CSU—Central Security Unit. Enhancement for the IC Identification Module (IIM). Will be
configured during boot and by eFUSEs and will determine the security level operation mode as
well as the TZ policy.
• A-HAB—Advanced High Assurance Boot—HABv4 with the new embedded enhancements:
SHA-256, 2048-bit RSA key, version control mechanism, warm boot, CSU, and TZ initialization.
