This presentation is about ARM processor. It include it’s architecture,it’s ISA and pipelining structure. The programmer’s interface to the hardware. □ Two CPUs as example. ▫ ARM processor: ARM version 7. ▫ SHARK. □. Digital signal processor (DSP). Analog Devices recently introduced eight SHARC processors as part of a new, high-performance, power-efficient, real-time series that delivers peak.

I was happy to see that part, then realized that I haven’t used a floating point operation in a long time. It can’t hurt though, to have those FPU instructions available in case.

Not a low-power CPU for sure. Every time I look at Blackfin it seems so media-oriented. Second generation products contain dual multipliers, ALUs, shifters, and data register files – significantly increasing overall system performance in a variety of applications.

Makes me think that for relatively simple stuff RS, I2C, etc. The F has a straight address space, and multiple busses to allow it to do DSP thingys like load and store, plus incrementing pointers in one cycle. I can either spend my time writing and learning a whole lot, or pulling my hair trying to figure out how to get someone else’s stuff to work. Hardware buffers are required to block the outputs until the CPU will be fully initialized.

The internal architecture and the instruction set are miserable. This is still a ‘new’ project -jg Reply Start a New Thread. I guess that will be difficult. I’m also turned off my the usual reports of bugs in libraries and so forth. I hope TI makes the C28xx family in at leastor bettermore betteror even more MHz someday soon.

SHARC vs ARM dev board, audio

Look at the CPU registers. It is rare to see any 32 but uC FLASH over Mhz, and often real memory bandwidth is quite a way below that, when wait states and cache effects are added.

In addition to satisfying the demands of the most computationally intensive, real-time signal-processing applications, SHARC processors integrate large memory arrays and application-specific peripherals designed to simplify product development and reduce time to market.

Then I have a couple hundred lines of fast stuff that needs to go in RAM. I don’t care for lab instruments. Reply Start a New Thread. Slow external bus, no cache. So the TI eZdsp makes my happy since I just jumper it’s headers to breadboards filled with whatever add-ons I need. But I would agree that the procesosrs RAM supply is a bit skimpy and unfortunately not contiguous.

How do they compare? I’m better off writing my own.

Please Select a Region. If a grandma had the dick, she would be a grandpa. The CPU is 3.

I don’t know if the F instruction set is very “orthogonal” my brief flirtations with its assembly language suggests it’s not verybut it’s certainly nowhere near the PIC league of klunkers. Many of the 28xx family members do not have the MsBSP port.

Sign in Sign proceswors Remember me Forgot processprs or password? That’s all I want. That’s one reason I was happy when the F came out. Seems like an Ok arrangement. The other thing it does is makes time-domain pulse sequences of arbitrary on and off times with 1us resolution, and with up to N transitions per sequence with NO jitter, also using compare match hardware. But it does have a bit more RAM, so I might end up using it just for proxessors.


You can use the benefits of the high clock rate only if the code is executed from the internal RAM. These products also integrate a variety of ROM memory configurations and audio-centric peripherals design to decrease time to market and reduce the overall bill of materials costs. I don’t think it’s PIC-like. Irrespective of the specific product choice, all SHARC processors provide a common set of features and functionality useable across many signal processing markets and applications.

Have you worked with any others like the 56k parts for power stage driving? Plus, the F makes everything else a cinch like implementing a communications interface that is both machine and human understandable.

The internal ADC is crap. Yeah, that’s why you have to put the fast code in fast RAM. Good luck Michael Kellett www.
