I remember discussions a while back about an async MCU which I don't think was an ARM. Here is a clockless ARM CPU core that seems to be ready for use. Anyone know if there are chips out there with this design? http://www.handshakesolutions.com/products_services/ARM996HS/Index.html Personally, I don't get the advantages of clockless processing. If you are doing embedded, real time wor...

Hi there, I have been using 8/16 micros for a number of years and am finding the need to step up to 32 bit processing. I am tempted to jump into the use of microchips 32bit processors, but based on extremely the poor technical support I have received in the past I am thinking about moving over to an ARM product. Another for moving to ARM is that I will also likely start using the Actel lower p...

Hi, [Trying not to hijack the "Best dev kits for ARM Cortex" thread] I'd appreciate comments re: vendor offerings for ARM *simulators* (i.e., forget the "device/vendor-specific I/O's) and their (presumably) code generating counterparts. I do most of my development and testing *without* target hardware so appreciate tools that let me exercise my code without being tethered to a physica...

Hi All, Not sure if this is the right forum. Pls. point me appropriately if not. My question: Does anyone know if gcc generates dsp instructions when available for ARM processors such as ARM926EJ-S? If so, what flags must one enable? Even better, can anyone point to sample dsp code for ARM? Thanks.

Someone I know is about to start a new hardware development effort with the ST10. Seems to me that the ARM would be a better choice from the standpoint of unit cost and development tools. Either processor will do the job. What do you think of the ST10 vrs Phillips or Atmel ARM?


Soft ARM in an FPGA

I'm trying to understand what the advantage of putting a soft implementation of an ARM in an FPGA (Altera or Xilinx) is. The reason I ask is both of them have entirely adequate 32-bit soft processors of their own. Each has a nice development environment with lots of IP, growing ecosystems, and will run easily 3x to 4x the clock speed of the soft ARM. I suspect it has something to do with "indus...

On their website (http://www.arm.com/products/CPUs/) ARM distinguishes application, embedded and secure cores but the distinction between application and embedded cores seems somewhat arbitrary and not explained very well. I'm probably missing something so I'm wondering if someone could explain what these categories really mean. I can see how the different cores have different features ...

Hi everyone! Can someone tell me where to get hints on getting started with Rowley's Crossworks for ARM. What I'm looking for is a bunch of examples and project samples in order to clarify my learning process. I've already worked with IAR and Keil, but I'm facing problems with Crossworks for ARM 1.7 that the documentation available at Rowley's site did not resolve.

Hi, Has anyone successfully programmed an LPC2103 using Rowley Associates CrossWorks for ARM and the ARM USB CrossConnect? It does explicitly support LPC2104, but it doesn't say anything about 2103. I know the LPC2103 is newer, but it also has less memory, and I don't know if that makes it impossible to support it. Any experience? Thanks in advance,

Most of the ARM microcontrollers seem to require 3.0-3.6V supply, though many have an internal regulator for 1.8V for the core. Are there any ARM microcontrollers that can run directly on a lithium cell (e.g., 2.0 to 3.2V supply), avoiding the need for a boost regulator or charge pump? There are a lot of 8-bit microcontrollers that will do that, so I'm somewhat surprised not to find a su...

I'm working to cross compiling (for arm, with arm-elf-* tools) some pieces of code and I have to pay really attention to the compiled size.

And If not, I hope someone can tell me were I'm wrong. This are t...
