Security
S-GOLDradio has the following security features:
TM
• Secure Boot and Flash Update
• SHA1 HW acceleration
• Secure Debug
• 128-bit customer defined efuse key
• Anti-intrusion logic.
Audio
Besides the telephony voice CODECs supplied by the Firmware running on the TEAKLite® DSP core, the
ARM926 core enables running high-quality audio CODECs such as MPEG-1/2 Layer-3 Decode (MP3),
AAC+ or AAC++. Audio streaming is supported according to the 3GPP PSS Release 4 standard.
The output of audio and voice codecs can be mixed and routed to the integrated Hi-Fi Stereo voiceband
supporting CD-Quality. Alternatively, the audio can also be sinked to a mono loudspeaker using the
integrated hands-free amplifier.
Video and Imaging
S-GOLDradio allows connecting an external camera module over an ITU-R BT656 compliant interface
TM
and a display module over a microcontroller-like parallel or serial interface. Furthermore, ARM's MOVE
coprocessor is integrated to accelerate video encoding algorithms (for example, H.263 or MPEG-4). This
fulfills basic multimedia requirements and allows connecting commodity cameras and displays without the
need of an additional multimedia IC. The computational power for encoding and decoding still pictures
(JPEG) and video sequences (H.263 or MPEG-4) is provided by the integrated ARM926 core. Over-the-air
interface JPEG pictures and H.263 or MPEG-4 videos can be sent or received as MMS by means of
(E)GPRS.
