I think "LPC cortex M3" is on the way. ;) M. Paul Curtis wrote:

Very interesting although the datasheet links aren't working yet. I can't see any advantage to using it over the LPC2101 even though it would be more I/O efficient with the Cortex, it still only runs at 20MHz. But I guess with the Cortex core it would be far more suitable for low-power designs. Mouser lists the LM3S102-CRN20 in stock for around the $2 mark. They also have more information about the chip than the manufacturer (at present). It seems a bit incredible that they claim up to 4x better code density than 8051's. I think I'd better read-up on the Cortex core a bit more. Thoughts anyone? *Peter* Paul Curtis wrote:

I like the form factor; t will be much easier to hand solder. Sure, it has less pins and therefore less IO, but it could be a useful part. I do have a hangup with the predatory pricing of the development board. It is interestiing to see how the various manufacturers deal with this. One example is Xilinx and their relationship with Digilent; a complete Spartan 3 board with a 1,000,000 gate FPGA with all the necessary software (not a demo version) for $149. Less if you want a smaller device. Microchip and Atmel stumble all over each other trying to underprice the other on development products. Richard

Motorola ran into that about 10 years ago when they released their MC68EZ328 EVB for $50, it was well below their cost to produce them and simply wanted to ensure that engineers could justify purchasing them. Companies then started to order the EVB in thousand lots... TomW -- Tom Walsh - WN3L - Embedded Systems Consultant http://openhardware.net, http://cyberiansoftware.com "Windows?

Very interesting in deed, some thoughts; - the 20 MHz might be artificial because I saw presentations from ARM talking about 100 MHz for the Cortex M3 - the core is VERY new, meaning this is the first implementation in silicon available, expect some debugging of the core and an Errata Sheet coming up soon!? - Once a year has gone, there are going to be more products using this core with the first problems debugged, so for now, watching it is just fine, using a proven ARM7 core is our better current option. - May be the biggest issue, it is not "ARM" compatible, only "Thumb" compatible. You need to touch any software you wrote for an ARM micro because this core does not support ARM mode and by definition of all previous devices any entry in exceptions (interrupts) are in ARM mode. Cortex is probably the core to go with in the future, the question remains when to start using it.

There are errata sheets. The core is from ARM, so it's well tested one assumes. > - Once a year has gone, there are going to be more products > using this core with the first problems debugged, so for now, > watching it is just fine, using a proven ARM7 core is our > better current option. Perhaps, but the Cortex-M3 is designed for low power, the core taking 1/3 the power of a comparable ARM7. And it's cheap and will probably get cheaper. > - May be the biggest issue, it is not "ARM" compatible, only "Thumb" > compatible.

Although not binary compatible, Thumb-2 is pretty much an ARM instruction set... It only affects you *if* you use assembly language. > Cortex is probably the core to go with in the future, the > question remains when to start using it. Want to be a Guinea pig ;-) One assumes that there will be other vendors offering Cortex. Note that the Stellaris has the single wire debug and single wire trace facilities which ARM cores do not have. The Stellaris family is nice, Cortex-M3 is a nice little core. -- Paul.

So finally writing a new Thumb-2 compiler eh?

Hello,
Has anyone looked at the CodeSourcery compiler for ARM??? They are
claiming support for the thumb-2 instructions. Any other gnu stuff
supporting Thumb 2???

Cortex-M3 is Thumb-2 yes, but more than that it's v7M. Thumb-2 has been around for a little in the GNU toolchain. Compilation is only half the story. v7M and ADIv5 are significantly different to ARMv6T2 and ARM7DI.
