Vampire 600: FPGA A600 Accelerator Preorder

[Mrs Beanbag]

If there are any plans to make an A1200 version I would put money down for that.

[Mrs Beanbag]

Majsta is it possible for the user to update the FPGA code? We do actually have an A600 that we don't use much, if it were possible, I could use it to try developing a faster CPU softcore, which I would like to try.

[Mrs Beanbag]

I don't have any VHDL or Verilog knowledge, yet...

[Mrs Beanbag]

I gather there are still plenty of spare LUTs on the FPGA, room for a lot of enhancements.

[Mrs Beanbag]

Perhaps one could simply set a pointer to the chunky buffer in fast ram, then set it off to automatically copy and covert the buffer to chipram as planar data

Or simply a command to shuffle the bits around in the data registers, so you can read 32 chunky pixels into D0-D7 and write out 32 planar pixels, or vice versa. That would be very easy to do since it could simply be hardwired into the register file bit by bit.

But I would first of all concentrate on making the CPU core as efficient as possible before adding extra features that no current software will use.
