Announces Broadband Communications IP Cores to speed up time to
market for Wired and Wireless Network ASIC/SOC manufacturers.
Initial IP Cores are optimized for 802.11
Audio/Video/Data Wireless Home and Corporate
Network System and Component Manufacturers.
Los Gatos, California, March 10, 2003: MetaVideo,
Inc., headquartered in Los Gatos, California, today announced the availability
of broadband communications IP Cores optimized for ASICs/SOCs incorporating
an 802.11-based wireless interface. The first set of cores supports
802.11a, g while the next set of cores will support all three standards,
namely, 802.a/b/g. With these cores, OEMs and IC manufacturers can
easily integrate an 802.11 wireless connection in their ASICs. The
target applications include: wireless corporate LANs, wireless TVs
and HDTVs and wireless audio/video/data distribution system in the
home.
“ Wireless manufacturers of 802.11-based components and systems will significantly
lower the cost and time-to-market of their products using MetaVideo IP cores,”
said Robert Stodieck, Director of Business Development for MetaVideo. “Moreover,
our IP Core building blocks have been partitioned to be used in a number of
Wired and Wireless Broadband Communications ASICs”, he added.
Wireless IP Core
Functional Blocks
The following IP cores are applicable to broadband Wired and Wireless Applications
and have been optimized for 802.11a and g standards:
Fast Fourier
Transform (FFT) and Inverse Fast Fourier Transform (IFFT)
The IFFT/FFT is a single configurable block is an optimized for performing
radix-4, 64-point IFFT (transmit) or FFT (receive). It completes one FFT in
192 cycles and can operate at 160 MHz.
Viterbi Decoder and
Viterbi Encoder
The Viterbi Decoder
is capable of performing soft decoding on convolutionaly encoded
data stream with convolution constant K=7. It can operate at 160 MHz.
Most the variables of the Viterbi decoder are parameterized and can
be
adjusted before synthesis and several others can be programmed
during operation. The
constraint length and the generating polynomials are also programmable.
The back tracing depth, which usually is chosen to be equal to
5xK can be varied
during operation. De-puncturing is also supported and the de-puncturing
algorithm pattern is also programmable. The high degree of programmability
of the decoder
renders it suitable to decode data which has been encoded using different
types of convolutional codes. The decoder is optimized for very
low latency.
Interleaver
/ De-Interleaver
The interleaver is a hardware dedicated block to perform the interleaving function
required by 802.11a, g. It operates on two bits at a time as they come out
of the convolutional coder. The de-interleaver implements the de-interleaving
function required by 802.11a. It operates on soft bits. The size of the soft
bits is defined by a parameter that can be specified before synthesis.
Mapper /
De-Mapper
The mapper implements all mapping functions specified by 802.11a, g. These
consist of BPSK, QPSK, QAM16, QAM64. The de-mapper performs the de-mapping
functions of 802.11a generating 4-bit wide soft bits. The 802.11a cores
are available immediately from Metavideo.
