• Programmable Data Length: 8, 10, 12, 14, 16, 18 or 24 bits per clock cycle
• PPI clock can be provided externally or internally
• External clock: 75 MHz TX/RX @ 16 bits, allowing connection to popular ADI high-speed
converters and HD video encoders/decoders
• Internal clock: up to 66 MHz TX/RX, for SCLK=133 MHz
• ITU-R BT.656 Internal Blanking, Preamble and Status Word Generation for TX modes
• Saves considerable DMA bandwidth by bypassing external memory
• Horizontal and Vertical Windowing of inbound/outbound data
• Programmable clipping of 8-bit output data
• Truncation of RGB888 values to RGB666 or RGB565 for flexible LCD connections
• Allows easy connection to 24 bit (8-8-8), 18-bit (6-6-6) or 16-bit (5-6-5) LCDs
• De-interleaving/Interleaving Modes for 4:2:2 YCbCr data, allowing efficient DMA transfer in
planar and interleaved buffer formats
• Optional sign-extension or zero-fill of received data

New Pixel Compositor Features
Why? Provides more MIPS for customer application
What is it? Hardware acceleration to perform overlays, color conversion, and alpha blending
• Significantly reduces processor core overhead associated with software RGB-YUV color
conversion and alpha blending
• Image/overlay from L1/L2/L3 memory
• Provides image data stream for either active-matrix TFT LCD panel or analog NTSC/PAL DAC
• Supports YUV 4:2:2 or RGB888 input/output data format
• Overlay content transparency ratio control (alpha)
• Support for transparent colors in the desired color space (RGB or YUV)
• Programmable color space conversion on either the main image, the overlay image, or the
blended output

Lockbox™ Secure Technology for Blackfin
Blackfin Lockbox technology is composed of a mix of hardware and software
mechanisms designed to prevent unauthorized access and allow only trusted code to
execute on the processor
• Safeguards as little as a single function, as much as a complete system,
or anything in between
• Ensures data integrity through authentication and safeguards confidentiality
via encryption of any or all of the system—from core IP/code security to data
integrity
• Performs digital signature authentication using Elliptic Curve Cryptography
and
SHA-1 (secure one-way hash)
• System designers can use ANY encryption algorithm they desire
to protect their code or other assets
• Non-volatile One-Time Programmable memory (OTP) provided
for secure key storage
15
• Platform for digital rights management support
Lockbox Secure Technology for Blackfin
Security Benefits
IP protection
• Ensure code has not been altered and comes from the appropriate source
through authentication
• Verify a code or data image against its embedded digital signature
Prevention of mass copying
• Support cryptographic encryption/decryption when confidentiality is required
• Utilize unique chip ID to “lock” processor to one specific boot source/device
Digital rights management
• Identify valid media content
