hi all,
I am newbie to LPC 2106? what is th machine cycle time for LPC 2106?
How much time ir will take to Execute one instruction..

Hi,

In the ARM7DTMI-S processor (used in the LPC2106) the
CPU Cycle is equal to the Clock Cycle.

The Clock Cycle is defined by your XTAL frequency and
your PLL settings.

For example, the "subs" instruction takes one cpu-cycle,
so if the XTAL * PLL frequency is 60 MHz, the instruction
takes 16.6 nS.

Branch instructions takes more cpu-cycles, for example
"bne goto_label" takes 3 cycles to jump.

For the LPC2xxx family you have to add MAMTIM cycles
to branch intructions cpu-cycles if your are using the MAM.

Refer to ARM7DTMI-S processor datasheet (www.arm.com)
for instruction CPU Cycles and read the MAM section
in the LPC2106 user manual.

Download the delay.zip example from the group
files section for additional information.

Regards,
Boris Estudiez.-

Dear Boris,

I am using Lpc 2106 processor with 10 MHZ crystal, Multiplier value would be
5.

so ,one instruction will take 0.00002 ns ,Is it correct?

Please reply me...

With 10 MHz crystal, and PLL multiplier of 5 , the frequency will be 50 MHz,
or 20 ns.
So a machine cycle will be 20 ns. Many of the ARM instructions need more
than one machine cycle.

Depending on your value of 'many', IMO most require 3 cycles to
complete, but with the 3 stage pipeline that means 1 instruction
completing each machine cycle.

But that's when memory delivers an instruction in 1 cycle: RAM will, but
FLASH won't. It can approach it with the flash speedup thingy enabled
(MAM?).

That would be 20ns

(10*5 = 50MHz) so you get 1/50000000 = 0,00000002 seconds = 20ns

Why not use one of the LPC timers to measure how long it takes? Just setup a
timer and start it right before you enter the loop, then stop it again right
after you exit the loop.

Then check the counter register value and multiply it with 20ns (assuming
you run it at 0 prescaler).

if i use one for loop means how much time it will take. in LPC 2106 Keil 3
MDK..

I dont have Digital Oscilloscope.So i am not able to measure..
