Hello People!!! ;-)

Can't remember whether I've ever mentioned it, the main project I'm working on at the moment is a new type of professional night-club /studio /theatre lighting control system. Basically I require a microcontroller that can process several thousand (probably no more than 4096) bytes of data upto 25 times a second. For each byte the processor will probably have to execute upto 50 instructions (80 cycles say). As you can imagine, this is quite a tall order! At the moment I am experimenting with an AT90S8515 (which is an AVR, not a 8052) as this can perform upto 8MIPS, which means it's nearly up to the task. Also, it has 3 16-bit data-pointers which is important in my application. I could live with two data-pointers such as in the DS80C320, but this chip is not fast enough. I've decided I would like the system to now work with 16-bit data, not 8-bit, so I think a 16-bit processor would be more suitable. Does anyone know of any FAST 16-bit 8052 devices? (I rather use a device that resembles an 8052 than some new device which will take me longer to learn about). The device needs to run from an external program memory, and access preferably more than 64KB (although that would do I suppose) of data space.

Cheers,

Matt.
