GoMotion
Video Decoder
The Ligos GoMotion Video Decoder is available in four versions, the first
a pure C implementation, the second an Intel Pentium(R) II MMX optimized
version, the third a Pentium III SSE optimized version and the fourth a
version optimized for SSE2 on the Intel Pentium 4 processor. The version
used for the processor in use is determined by querying the compatibility
with feature sets for MMX, SSE or SSE2. Failing compatability with any of
those, the tool defaults to the C implementation.
The Ligos GoMotion Video Decoder provides
a fast, flexible, easy-to-use infrastructure to support emerging applications
built on top of MPEG. The application returns timing information indicating
both decompression performance and total decoding plus rendering time. This
particular player requires graphics cards based nVidia's GeForce or GeForce2
chipset and at least DirectDraw 6.0. The performance metric is the frames/second
used to display the video.
eJay
MP3 Plus 1.3
Canon eJay MP3 Plus 1.3 is an application that lets a user work with audio files.
A user can listen to audio files, create personal playlists, extract audio files
from CDs, and convert music files between WAV and MP3 formats. The Canon eJay
MP3 Plus 1.3 application is used in this context strictly as a tool to convert
WAV format audio files to MP3 format audio files. To simulate the typical user
experience of creating entire CDs of music, a large continuous WAV file workload
was created from multiple audio tracks.
The performance tool takes the WAV file and, via eJay MP3 Plus
Encoder, converts it to MP3 format using the normal method of encoding. The
WAV file is encoded at a rate of 128 Kbits per second. The time, in seconds,
it takes to actually encode the WAV file to MP3 format is used as the performance
metric. The eJay MP3 Encoder has been optimized for the use of SSE instructions.
Summation
I’m happy to say that
1700MHz is already enough to beat the 1000MHz Pentium III Processor that was
performing better than the 1500MHz Pentium 4 in specific Home/Office tasks.
Other good news is that the Pentium 4 Processors became much more affordable
as of today. The 1.7GHz unit as confirmed by Intel is starting at an interesting
price of 352$ USD in Quantities of 1000, quite an improvement don’t you
think? The Pentium 4 will be available in OEM and Retail versions (No RDRAM
/ 128MB RDRAM and 256MB RDRAM). The price drops on the Pentium 4 and Pentium
III processors are without doubts great news for people planning to go INTEL.
Unfortunately the high priced RDRAM memory and 850 Mainboards that cost alot
will still limit the P4 to people that have the extra money in their pockets.
What we need now is an alternative platform to the 850 Chipset that supports
SDRAM/DDR memory and the Pentium 4 might be in business! Luckily this is not
a dream, Intel and third party corporations are already in the works for such
solutions. 2001 is going to be an interesting year!
