Short summary: can anyone suggest what might be used these days instead of an AMD 2910 sequencer ? Long summary: As I was working on my latest hardware design, it became clear that it fit perfectly into a classic microprogrammed architecture, with the difference being that the execution unit is something weird (non-arithmetic). Having used the 2901 stuff years ago, I called AMD and found out that this is basically obsolete, and that "everyone's going to RISC". Well, that may be swell, but I still need a microprogrammed sequencer. And I don't mean the PAL versions, since I need something with a writable control store. I'm getting some documentation from AMD on CMOS versions of the old 2900 series, but in the meantime I'm soliciting info from the net as to what people are using these days. I'm looking for something like the 2910 which supports at least a 4K microprogram memory, with a clock speed of at least 100 ns, preferably 50ns. Sorry, I can't reveal the application, but it requires being able to generate lots of digital signals every 100 ns in a programmable way. Obviously one alternative will be to use the 2910, but there must be something niftier around by now. Thanks. -- Rainer Malzbender Real programmers build hardware.
