Imagine a low-cost video processor for
small screens that requires little energy
and still packs a punch. Vivace Semiconductor's VSP100 offers all of these
qualities, providing QVGA (240 by 320
pixels) playback in real time at 30
frames per second (). And
since it's quite capable of handling
today's compute-intensive standards like H.264, MPEG-4, and WMV9, you can
design your next-generation consumer
device with confidence.
The VSP100 is designed for portable
media players, video cell phones, and
other devices where the screen is less
than 2.5 in. Powered by a custom tri-core
multimedia processor that includes a
dual-core DSP engine and a 150-MHz
RISC CPU, it offers deblocking, deringing, scaling, rotation, and other post-processing utilities. It also includes an
LCD/VGA controller with 32-bit precision
for programming the resolution and timing
to support several video standards.
With battery life in mind, the VSP100
operates at a low clock frequency. Its integrated power management supports
three power modes: active, sleep, and
power-down. The end result is a power
consumption of only 25 to 50 mW during
media playback, and it consumes virtually no power in the idle state. The chip
also includes an integrated "video
aware" DMA memory controller that is
fluent in DDR and SDRAM, so a complete low-power system may be designed
around it.
The fully programmable VSP100
includes a complete software development environment with integrated compilers, debuggers, assemblers, and profilers. The device can be purchased with
a development platform and reference
design that accelerates and eases development, debug, integration, and hardware/software testing.
The VSP100 will start sampling next
month with 10,000-piece pricing at
about $6.
