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.

Then I have a couple hundred lines of fast stuff that needs to go in RAM. Please Select a Language. Not much, especially for the DSP tasks. I don’t care for lab instruments. If your goal is a very fast bit-banging, you might want to consider FPGA. The internal architecture and the instruction set are miserable.

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.

The Blackfin is a fixed point DSP so its harder to work with for high quality audio. So the TI eZdsp makes my happy since I just jumper it’s headers to breadboards filled with whatever add-ons I need. I tend not to like SBCs with someone else’s chosen peripherals, when I’ll likely want something slightly different in my final application.

I was happy to see that part, then realized that I haven’t used a floating point operation amr a long time. That is all fairly easy on the Syarc I’ll take another look this weekend if I’m bored and surfing the web. I guess that will be difficult. Another route is the Analog Devices Blackfin which you might like because their are some open source tools not common for DSPs and even some ‘open source’ hardware.


The internal ADC is crap. It can’t hurt though, to have those FPU instructions available in case. Not a low-power CPU for sure. But it does have a bit more RAM, so I might end up using it just for that. I don’t recall seeing the kind of peripherals I’m after. Now I’m about ready to build an important piece of lab instrumentation with this device.

So there is a way for TI to scale up the speed from the F without worrying about the flash. Can anyone else provide some insight on the matter? There could be the intermittent states of the PWM outputs at the startup.

But that could still be useful for stuff. Plus, the F makes everything else a cinch like implementing a communications interface that is both machine and human understandable.

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. 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.

Look at the CPU registers. 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.

SHARC vs ARM dev board, audio

I’m also turned off my the usual reports of bugs in libraries and so forth. The memory is addressed as bits, and the external interface is 16 bits wide. For the recent project, I need to count a QEP encoder, and output bits with very low jitter every time there’s a compare match. I don’t think it’s PIC-like.


SHARC Processor Architectural Overview

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. I don’t know why you say it’s not bit. Is that a chip bug? I’ve done several projects with TMS28xx and I am not so excited about it: That’s all I want. How do they compare?

proceesors This increased level of performance and peripheral integration allow third generation SHARC processors to be considered as single-chip solutions for a variety of audio markets. I hope TI makes the C28xx family in at leastor bettermore betteror even more MHz someday soon. I’m better off writing my own.

I could focus on doing stuff right away on a Processos chip rather than a whole lot of groundwork just to get the thing running.

That’s one reason I was happy when the F came out. I used an ‘f and I was quite happy with it – true it does run a bit warm but I liked the on chip ADC which is pretty damn fast.
