|Data Width||16 bit||Op-codes are 8 bits wide
Whilst the internal data paths are all 16 bit, the external data bus is 8 bits wide.
|Address Width||16 bit|
|Number of Registers||7||R0, R1, R2, R3 : General Purpose
PC : Program Counter
SP : Stack Pointer
PS : Processor Status
|Clock Speed||DC to something||Currently looks like about 20kHz.
As well as free running it will be possible to single step cycle by cycle to watch the logic operating.
|RAM||256 Bytes||Still can't believe I managed to finish it !|
|PROM||256 Bytes ?||Depends how much soldering endurance I have left.|
|Power||~500W||This is dominated by the power needed to drive all the
LEDs. The logic itself doesn't take very much.
|Weight||~½ ton||Bit of a guess at the moment|
|Number of Transistors||15,300
|For the processor. Note that a fair proportion of these
are used to drive the LEDs (pretty much one for one).
For the RAM.
|Number of LEDs||8,500
|For the processor.
For the RAM
|Area (core)||~15 m2||It's quite thin, 10cm, so volume is "only" ~2 m3
|Area (memory)||~3 m2||One bit of RAM takes one square inch. I expect PROM will be about half that (yet to design).|
By way of comparison Wikipedia gives these transistor count/area numbers for other processors:
