Also XScales from Intel max out at 800MHz. As others have said actual performance is more important. If the DSP instructions in blackfin help you then I would expect it to be faster almost regardless of clockspeed.
If not then -given similar cache- then normal ARMs and Blackfins should be fairly comparable since they're both pipelined, scalar RISC processors, with similar ISAs. The Cortex A8 Samuel mentions is superscalar and can perform 2 instructions per clock quite often. BTW Although most insns on both at single cycle, multiply is multiple cycle on both ARM and Blackfin, I think divide is too. Probably some of Blackfins DSP is also. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Samuel A.
