While this may change in the future, it is one of those hard and strict rules that is here today(ie. This isn't like ordering pizza over an autopatch).

It sounds rudimentary so far but I am sure that over time the capabilities (new software development) will proceed and its capabilities will be enhanced and it will make a very interesting tool for amateur radio communications, experimentation, and learning DSP. There will be alternatives as you will now be told. In other messages, John Alberts has told us of the lack of capabilities of the Sound Blaster 16 with ASP. He is WRONG. I received my Sound Blaster developers kit via UPS yesterday at last. It is easy to see how John could have made the mistake he made. The manuals received in the kit describe two distinct pieces of processing hardware. One is called the DSP and the other is the ASP. The DSP has all the limitations mentioned by John in his statements concerning the capabilities of the Sound Blaster card (or lack thereof). It is a proprietary gate array surrounding masks from other chip developers to do stuff like DMA blocks of samples in and out, to convert PCM to u-LAW, 2 or 4 bit ADPCM, CVSD, etc. It directs the flow of MIDI commands, etc. It is a pretty neat thing in and of itself but it is NOT what we want. We want a full blown DSP chip, with a modified Harvard architecture and at least 16 by 16 bit -> 32 multiply, accumulate, read new coefficient and data in one instruction time. THE ASP is a real DSP chip and has all this. It is 512 words of off chip program memory, 512 words of off chip data ram, 192 words of X RAM on chip,128 words of Y ram on chip. X ram is program and sample data, Y RAM would be used for filter coefficients. THIS IS A FULL BLOWN DSP CHIP. It does NOT have the limitations John has told us the hamblaster overcomes. Indeed, on the A/D, D/A front, it is quite clear that the under $300 SB16-ASP is quite a bit MORE CAPABLE than hamblaster. It has two channels (16 bits each), D/A, and A/D. The sample rate is completely controllable by uploading a divisor to the control register. The lowest available rate is 5 Khz and the highest is 44.1 Khz. The processor runs at 12 MIPS so filters would execute at around 25 MIPS. This is because it has the typical DSP feature of multiply two numbers, read the next two, and accumulate the last result while shifting the pointers in two instruction times. That is plenty fast. I will be able to do dual channel modems for this card. Since the thing does not also have a UART, or SIO, we will have to the HDLC and UART functions on the chip when required. Other DSP developers have done this all on chip (Finland DSP development group on the Motorola DSP56001). We will be able to do a lot. John should be more careful when he makes flat statements about commercially available products. If he were a `real competitor' of Creative Labs, he could get into a bit of a hassle. I am following the philosophy of my dear friend, Phil Karn, in attributing to ignorance when possible, that which could be attributed to malice (in this case, competition). I told John in a reply to his mail that I doubted the accuracy of his statements on the Sound Blaster16 with ASP. I was correct. The Sound Blaster 16 with ASP is available from many places for under $300. The developers kit is $99, available only from Creative Labs. In addition to this, you must have a dsp assembler. The developer's kit provides COMPLETE tools for uploading and downloading programs to the ASP chip. I will be writing programs for the ASP and giving them away on your favorite ftp sites and through the ARRL download request service. These programs will be the basis of articles for QEX describing the algorithms and the operation of the sound blaster card in amateur radio applications. Phil Karn has devised a new link layer for packet, with FEC, etc. and I will be providing modems that use the ASP. I believe I can provide what the latest hamblaster announcements state and more in short order after I get the assembler for the ASP. I will do this as quickly as possible. I am a bit miffed that I stopped developing the Windows and DOS front ends and display stuff for the SB16 ASP after John's note because I thought the SB16 was too limited. Now it is full steam ahead.

Any referances to the ASP version was based on information from the "Ultimate Soundblaster Book" that I purchased from a local book store.

You'll never get rich selling to Hams. RWM I told John in a reply to his mail that I doubted the accuracy of his statements on the Sound Blaster16 with ASP. I was correct. JWA Not really.
