• L1/L2 Memory Architecture
The dual-core DSP processors offer performance
up to 250MHz, each compliant with IEEE
754 single-precision floating-point operations
and single-instruction, multiple-data (SIMD)
multimedia capabilities into a single instruction-set
architecture. The hardware engine provides hardware
implementation of signal and image processing
algorithms like Rotation, Decimation, JPEG Encoder,
Image Histogram, CNN, Integral Image, etc. to
offload the dual-core DSP’s loading and accelerate
video processing.

The Sensor Interface provides an interface for image
capture from CMOS or CIS sensors. The HT82V82
can be connected to a CMOS sensor directly through
the sensor Interface. In conjunction with an Analog
Front End (AFE) IC such as the HT82V48, it can also
be connected to a CIS sensor, utilising the embedded
Timing Generator.
• Enhanced Direct Memory Access – EDMA
• Sensor Input interface
♦
Support two 8~20MHz 3~6ch CIS line sensor
modules
♦
Supports two CMOS area sensor modules
• Output interface
♦
Serial interface: High speed 4-wire SPI up to
40MHz.
Parallel interface: TFT LCD display
The device also includes rich peripherals for UART,
SPI, I2C, 16-ch ADC, SDIO, EPI (external parallel
interface) to enable simplified interfacing to existing
control systems. A high speed synchronous memory
interface is provided for the popular DDR2/DDR3
memory.
♦
• Supports peripheral interfaces like I2C, SPI, UART,
SPI, Timer and 16-ch 10-bit ADC
• Supports External Parallel Interfaces – EPI
• SDIO interface
By providing a robust security boot mechanism, the
HT82V82 provides users with protected proprietary
intellectual property measures and prevents external
entities from modifying the user-developed program code.
♦
Supports two different data bus modes: 1-bit
(default) and 4-bit
Supports two different speed modes: Normal
♦
speed (default) and High speed
SD clock frequency of up to (fHCLK/2)MHz
SPI mode and MMC stream mode not supported
HT82V82 is the best choice for next-generation
applications that require image processing and deep
learning in one integrated package. These applications
span a wide array of video markets, like high-speed
double-sided Currency Recognition, License Plate
Recognition, Automatic Optical Inspection and Facial
Recognition.
