ESP32-P4 v3.x – Major Performance and Multimedia Enhancements
Espressif Systems has officially released ESP32-P4 chip version v3.x, introducing significant improvements in processing speed, image processing, power management, and security. This important upgrade is designed to further optimize high-performance HMI, edge computing, and smart IoT applications.
Sunrich Co., Ltd. recommends that customers currently developing or manufacturing products based on ESP32-P4 upgrade their firmware and update hardware designs as soon as possible to take full advantage of the new features and performance enhancements.
Why Upgrade to ESP32-P4 v3.x?
ESP32-P4 v3.x not only delivers substantial performance improvements but also resolves several known issues from earlier versions, including:
MSPI access errors during startup (Load Access Fault)
Secure Boot verification failures
DMA conflicts in specific scenarios
These enhancements enable developers to build systems requiring high-quality image processing, real-time responsiveness, and greater reliability.
Improved Processing Performance
ESP32-P4 features a high-performance dual-core RISC-V processor, with the maximum clock speed increased from 360 MHz to 400 MHz.
Support for Zb Bit Manipulation Extensions
Optimized PIE (Packed Instruction Extension) accelerator
Improved efficiency for complex algorithms and real-time data processing
Enhanced Multimedia Experience
Upgraded Image Signal Processor (ISP)
The ISP now includes several advanced image processing features:
BLC (Black Level Correction)
DPC (Dead Pixel Correction)
WBG (White Balance Gain)
CROP (Image Cropping)
These features help maintain excellent image quality under various lighting conditions.
Pixel Processing Accelerator (PPA)
The upgraded PPA now supports:
32 × 32 pixel block processing
YUV422 and YUV420 formats
Faster UI rendering and smoother video display
Professional Audio Support
ESP32-P4 v3.x adds a dedicated 160 MHz clock source for I2S, fully supporting high-quality audio applications.
