Ultra Low-Power Graphics and Co-processor
Advanced graphics and display capabilities at high-quality and
high-resolution are becoming standard features on mobile and
small form factor stationary devices as access to digital multimedia
content anywhere becomes widespread. Silicon Motion continues
to expand its Mobile Graphics product line with the introduction
of the SM502, to perform graphics and video acceleration with
the incorporation of multiple I/O functions supporting the multimedia
requirements of users on a single chip. Its rich feature set
are perfect for high quality display applications such as high
resolution handhelds/PDAs, handheld POS, video phones, security
systems, and other applications requiring the need for low-power
multimedia performance. |
