Talk:Freescale DragonBall

Untitled
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.

If 68000 is 32-bit, then Z80 and 6809 are both 16-bit conserning the same reasoning you posted.

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).

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.

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)

Clock speed of the EZ and AlphaSmart
There was also a 20MHz variant of the EZ variant, as used in the Palm IIIc and the Vx. Using the Dana/Dana Wireless as an example for AlphaSmarts using the DragonBall isn't the best idea because it is essentially a Palm handheld with a keyboard stuck on. The 3000, and most likely the 2000 use the DragonBall EZ CPU, and the Neo uses the VZ chip. Anyway, great article though! Kasm279 (talk) 20:04, 18 December 2010 (UTC)

MX-1 image
It is confusing to place the image of the MX-1 on the subject page, while it apparently belongs to the i.MX series which is not described on the subject page. Tomdo08 (talk) 23:58, 21 January 2018 (UTC)


 * I moved the image over to i.MX. Regarding correct identification: Check the codename MC9328MX1 in image and e.g http://phonedb.net/index.php?m=processor&id=52&c=freescale_i.mx1__mc9328mx1 Tomdo08 (talk) 00:24, 22 January 2018 (UTC)
