Talk:Freescale DragonBall
From Wikipedia, the free encyclopedia
The picture shows the name on the processor itself with a capital B: DragonBall. Shouldn’t the article do the same? —Frungi 22:48, 28 September 2005 (UTC)
- Indeed it would. Freescale declares the processor as DragonBall, so I did the rename. --Arny 09:13, 23 October 2005 (UTC)
Someone put this note on the main page:
[Quick reader note: The Motorola 68k was 16-bit so the Dragonball -- which is fully 68k-compatible -- should also be 16-bit. I wish I could find clarification of this. The ARM CPU range is however 32-bit.]
You were right, I've corrected that and included the actual specifications from Freescale. --Arny 09:13, 23 October 2005 (UTC)
The DragonBall is 32-bit:
- It's listed as 32-bit on Freescale's website.
- The Motorola 68k is not 16-bit. The first implementation of the 68k architecture (the 68000) was implemented with a 16-bit databus and a 16-bit ALU (IIRC), but this was hidden from the programmer, and the architecture has always been 32-bit, including 32-bit registers and instructions that operates on 32-bit datatypes. Later implementations of the 68k-core was implemented with a 32-bit ALU, and a complete 32-bit data and addressbus.
[edit] VZ speed?
Was it really 37 Mhz? The one in my Palm m515 runs default at 33 Mhz.
- I think you're right: Freescale website says 33 MHz, 5.4 MIPS. Letdorf 10:37, 9 November 2006 (UTC).
[edit] Name Origin
Did the name DragonBall Have anything to do with the DragonBall manga series. I noticed that three of the models have 'Z' in the name.
[edit] External Address Bus
It is a 16-bit processor with 32-bit internal and external address bus (24-bit external address bus for EZ and VZ variants).
Found supporting documentation for EZ at http://www.freescale.com/files/32bit/doc/prod_brief/MC68EZ328.pdf?fsrch=1. Can anyone verify VZ? - MSTCrow 22:37, 12 January 2007 (UTC)
