LPC21xx not fast at all?

2005-11-17 by rggmns

Hello,

Can sombody explain to me, how it possible that the LPC21xx with MAM
hardware only delivers approx 20 MIPS with a 60 MHz clock, and an
ANALOG DEVICES ADuC7xxx (with the same core?) is quoted to deliver 40
MIPS with a 40 MHz clock?

If the core needs several clock pulses to execute an instruction, why
bother using the MAM hardware. The flash delivers 128 bits (4
instructio ns) at 20 MHz (Did I misread the manual?)

Please explain.

Thanks
