[ CX6 is Popular Bring on the Boards ] Hey, PigBoy.
I saw your Bro tonite on SNL. I just love GoatBoy. But they had to use that cattle prod on him again. Is that how you acted at ISPCON ??
I knew you were a RaDiCAL dUdE. :-))
But hey, Who wouldn't be if they were being teased by High Speed Bandwidth. I really like that new song that's out, " I can't get no DMT Connection" It's a really catchy Tune.
Pat mentioned yesterday that the Ameritech Trial went so well that Paul Simon wrote a song about it. "Ma Bell don't take my xDSL away". I heard it might be a real big hit. He may even do a followup called "DMT and ADSL down by the School Yard"
Thanks for sharing with us.
What have they got planned for the other line anyway ??
Ray
You mentioned MPEG cards. I found this tonite.

DSP Boards -- Loughborough utilizes TI's C6201 -- U.K. concern grabs for PCI
By Ashok Bindra
Lexington, Mass. - To tap the capabilities of Texas Instruments Inc.'s 320C620 general-purpose digital signal processor, U.K.-based DSP board maker Loughborough Sound Images Inc. has unveiled a new development board for embedded and telecom applications. The PCI/C6200 is tailored for the high-speed PCI bus and comes with extensive software for code development and debugging.
In fact, the PCI/C6200 supports an integrated design environment using tools from Texas Instruments, Go DSP Corp. and White Mountain. Consequently, the board enables development of a variety of applications in voice processing, modems and speech recognition, as well as other general DSP development, said Kevin Parslow, president of Loughborough. The company recently opened its first U.S. sales office here.
The PCI/C6200's integrated development environment includes an optimized C compiler for code development in a high-level language familiar to programmers, Parslow said. He claimed that the fixed-point C compiler makes it easy to write code in C, so developers can sidestep the time-consuming assembly language.
According to Parslow, the compiler makes maximum use of the C6X's parallel execution capabilities, allowing up to eight instructions to be performed simultaneously.

Processors -- Matsushita provides single-chip solution -- Multiprocessor takes aim at real-time multimedia
By Yoshiko Hara
Osaka, Japan - Matsushita Electric Industrial Co. Ltd. has developed what the company calls a media core processor, integrating on one chip a DSP for serial processing and a very long-instruction-word (VLIW) processor for parallel processing. Its multiprocessing architecture targets consumer electronics products that process graphics, video or audio signals in real-time.
Among the applications for Matsushita's media processor is MPEG-2 decoding. MPEG stream analysis calls for serial processing while discrete cosine transform (DCT)/Inverse DCT requires parallel processing, operations allocated, respectively, to the DSP and VLIW processor, according to the company. The architecture enables real-time processing at a relatively low-frequency clock, the company said.
Among the design considerations was low power consumption. "We reduced the clock frequency as low as possible because the higher the frequency, the higher the power consumption," said Teiji Nishizawa, project leader of the processor-development project at Matsushita. The processor's internal clock is 54 MHz.
"The power consumption is about half that of conventional media processors," Nishizawa said. "The two types of processors consume less than 1 W. Together with the peripherals, the total power consumption of the silicon is still less than 2 W."
He said the processor can decode 60 fields/second for NTSC or 50 fields for PAL without losing fields, even if video images require a heavy processing load.
Low clock frequencies generate less heat, so inexpensive plastic packages can be used. "Generally speaking," said Nishizawa, "the price of processors used in consumer products is about one-tenth that of equivalent-performance processors used in computers. We believe we can lower the price of media core processors for consumer products."
