Internal Architecture
The DMN-8600 can accomplish very compute-intensive signal
processing tasks because it integrates multiple high performance
processing modules on a single chip (see
):
•
Two SPARC processors, with integrated audio DSP, I-cache and
memory, host functions, and a 2D graphics engine with DVD
subpicture decode and a 32-bit RGBA OSD/GUI accelerator with
scaler and flicker filter
•
Video DSP
•
Motion estimation unit
•
High-performance memory controller (for audio, video and graphics
data), with a 32-bit data bus for support of 8 to 64 Mbytes of external
SDR or DDR SDRAM, SGRAM or FCRAM
The DMN-8600 supports multiple external interfaces:
•
One video input and one video output interface to external
ITU-R BT.656/601 video decoder and encoder chips
•
Dual-port IDS (inter-device serial) TDM (time-division multiplexed)
audio input, and quad-port IDS TDM audio output interfaces to
external audio decoder and encoder chips
•
IEC-958 S/PDIF audio-out interface
•
External generic host bus interface
•
Serial I/O interface controller for infrared port, general purpose serial
I/O, modem, etc.
•
Storage device interface controller for IDE/ATAPI devices or
non-ATAPI devices (low-cost optical loaders)
•
IEEE1394 link layer interface (with 5C encryption) to a required
external Physical Layer chip
