Hello. I am looking at some possible processor architectures for future products. Intel offers some Pentium III and Pentium M derivatives plus chipsets that include peripherals and graphics controllers with 2D acceleration. I have browsed through Freescale page looking at their several PPC families. There are some very interesting SOCs based on medium to high end CPUs (which I guess...

Hello, We are searching high and low for a set of header files (and C files?) for the powerpc 555. tpu_pta.h is what we know we need. I think there is also an associated C file (tpu_pta.c) but I'm not certain we need it. Anyone have a clue? Web searches are turning up very little. Briefly, I've got a group of students trying to use the timers to figure out how long a signal is high f...

I am new in 32bit embedded systems. Can you advise me what architecture I should choose for learning and future projects with embedded Linux? At the moment I am a bit confused because of the following information: 1. x86 has the "inherited inefficiency" - I do not really know what it means. 2. x86 has the higher overall cost - After looking for SBCs I can not confirm this rule. ...

Hi, I'm trying to write a graphics demo program on an ML-300 board with embedded PowerPC CPU and 128MB of RAM, no graphics acceleration chip. I got the linux kernel running, and have been advised that regular X11 will not run because it takes too much memory and I need to run some other memory-extensive tasks on the background. Does anyone know of a good widget toolkit that can solve...

I have tried to sort out the "unbdefined reference sbrk" message. First my system comfiguration, then my attempts. I have to build an executable (elf file) for powerpc with gnu-gcc 4.2.2. installed on windows XP.

At the risk of starting a flame war, which choice have people really made with regard to Little-Endian vs. Big-Endian for those processors where it's a design choice (ARM, PowerPC,...)? I'm asking in the context of using such processors in embedded applications where compatibility with anything in the outside world is not a factor.

I am getting the OOPS message that follows and have been having a very difficult time determining what is causing it. According to "PowerPC Microprocessor Family: The Programming Environments for 32-Bit Microprocessors", "When an exception occurs, bits 1-4 and 10-15 of SRR1 are loaded with exception specific information." SRR1 is 00089032, so bits 1-4 are 0000 and bits 10-15 are 001000. U...

Hi guys. I'm doing some investigation regarding TRACE32 Simulator. I'll be simulating a board with a PowerPC chip installed running in pSOS. When using the board, I simply connect it through RS232 to my PC. To test it, I use the Hyperterminal in Windows.
