Geode™ CS1301/CS1311 Multimedia Companion:
Media Coprocessor
General Description
The National Semiconductor
CS1311 multimedia companions act as coprocessors to
decode multimedia in National’s Geode single chip proces-
sor-based systems (i.e., SC1200/SC1201, SC2200, and
SC3200, hereafter referred to as SCx200). They provide a
multimedia experience for an Information Appliance (IA)
user that cannot typically be achieved on a PC.
By implementing a dedicated coprocessor to perform multi-
media tasks, a high quality video viewing experience can
be achieved. This high quality is achieved by having a
coprocessor architecture that is ideally suited for decoding
digital media. In addition, since the decoding is not occur-
ring on the SCx200, system events cannot interrupt the

coprocessor’s task of decoding media and thereby causing
stuttering of sound or interruptions in the video.
Lower power consumption can also be achieved using the
SCx200/CS1301
CS1301/CS1311 has an architecture specifically designed
for decoding media. The architecture is such that while
decoding media, power is not consumed by portions of the
system that are not used to decode media. Since the
SCx200 is not decoding the media locally, it is able to go
into a lower power state. When the CS1301/CS1311 is not
decoding media, it uses almost no power.
Additionally, since the architecture is designed for decoding
media, fewer CS1301/CS1311 cycles are required.

... CS1311 EEPROM Revision 2.2 1.1 IMPORTANT DESIGN NOTE The CS1301/CS1311 was designed general pur- pose media data processor. As such, the CS1301/CS1311 is capable of far more than the current National CS1301/CS1311 solution. The solution that National is pro- viding is only one possible implementation of the CS1301/CS1311 and only this implementation is fully sup- ported by National Semiconductor. In order to maintain software compatibility with National’ ...
