A new home for my ZX Spectrum

My loved ZX Spectrum has been donated to the Internet Museum.

ZX Spectrum @ Internet Museem
Using this computer, I have written lots of programs using Basic and machine code. You can do a lot using 48k of memory. (This is more than the Commodore-64 which had only 40k of usable memory.) I have also made some music using the MIDI interface that was also donated. Some other gadgets I donated was a light-pen, two joysticks and lots of games.

The ZX Spectrum was a very useful computer. Now it has found a new home. You can visit it at the Internet Museum.

Automatic synthesis for high reliability

Synopsys Synplify® Premier can be used to synthesize high reliability designs for space and other applications where high energy particles can influence the functionality.

In Space, high reliability designs are needed. NASA image – Public Domain.

What Synplify Premier does is to insert redundant logic (TMR) that votes for the correct outcome of a function. It inserts ECC codes for memories. It implements FSMs in safe ways. It can also insert logic to report about errors.

What is good about this is that now you don’t have to insert and verify all of this yourself in RTL. Synplify Premier does that part for you.
