Hello Everyone, I like to know the meaning of TDMI-S. Anyone with any information?? I have searched ATM7TDMI-S Technical Reference Manual, but unable to find. Sudip Yahoo! India Matrimony: Find your life partneronline. [Non-text portions of this message have been removed]

T - Thumb mode support (16-bit instructions) D - On-chip Debug M - Multiplier I - ICE S - Synthesizable core, this means that when the chip is laid out the core does not have to be a single physical block, it can be scattered about the die. This also make die shrinks easier. Richard --- In lpc2000@yahoogroups.com, sudip nag <sudipnag1@y...> wrote: > > Hello Everyone, > > I like to know the meaning of TDMI-S.

The non-S cores are "pre-laid-out" for various process technologies by ARM. The S cores are provided as VHDL or whatever and the chip designers have far more flexibility in how they implement the chip. In essence this boils down to much the same as Richard has already stated. If you want really extensive documentation on the cores, check out: http://www.arm.com/documentation/ARMProcessor_Cores/index.html From a typical perspective (ie. people designing with the chips or writing software), I can't see any material difference between S and non-S parts.

AFAIK, the non-S types can run higher JTAG clocks (-S types only up to 1/4 of the core's clock, non-S even higher then the core-clock). But it could be, I am mixing infos :-) -- 42Bastian Schick

As I always tell my kids: The day you don't learn something is the day you die. Thanks for correcting my understanding of this. I always thought the there was a speed restriction for all devices of 1/6 the core speed. According to http://www.arm.com/support/faqdev/4168.html there is no maximum (apart from process issues) for hard cores (TDMI) and there is a 1/6 limit for soft (TDMI-S) cores for deglitching flip-flops.

If I didn't use the Flash Utility everyday I probably wouldn't be making this request. But as I do I am wondering whether Philips apps in Hamburg can make a few changes. ---- 1. Skip the splash screen 2. Assign shortcut keys to the buttons or at least default the upload button (I'm not a mouse man, I'm a keyboard man) 3. Display the filename in the title bar as the filename window is too short for long paths. 4. Add a filename MRU? 5. Just for me I know but user buttons that send a programmable coms string as I use control sequences to activate my ISP monitor chip. i.e. "<ctrl A>PGM0P" places unit 0 into program mode. The DTR/RTS signals assume that you have these lines available etc. Personally, I prefer simple 3-wire coms. ---- What I would really like is for my terminal program (Teraterm) to share the coms port and call these functions directly. I'm guessing that won't happen. Those Buffer operations would be useful but just seem to bomb out on my PC. Anyhow, I always have the option of writing my own Flash Utility. It's just that windows programming seems such a distraction when all I want to do is embedded code. TIA *Peter*

Try lpc21isp at http://guest.engelschall.com/~martin/lpc21xx/isp/ This has the benefit of being command line (ie easy to run from batch files or other tools). It is open source, meaning you can easily modify it to be used as a manufacturing jig etc. It works under multiple OSs. The last time I checked, the Philips application still was quite fussy about some start-up conditions. lpc21isp had similar problems but they were fixed very quickly.

So should I empty my back pocket and go out and buy a copy of Visual C? :( :( :( *Peter* Charles Manning wrote:

Yes, of course, as Frasier would say. The website said vc6/7 but I just had a look at the source code and it mentioned Cygwin. I'll try that. *Peter* embeddedjanitor wrote:

Bastian, on the LPC2000 family the JTAG clock is limited to CPU/6 Bob --- In lpc2000@yahoogroups.com, 42Bastian Schick <bastian42@m...> wrote:
