This is configured in the startup.s. You can read the current peripheral
clock in the debugger (simulation or JTAG) under Peripherals->System Control
Block->VPB Divider.

The crystal speed and pll setting are also involved. You can take a look
at the newlib-lpc support library ( http://www.aeolusdevelopment.com ) for
some examples that show the various values interact and give a resulting
clock. It's not Keil but it is fairly straightforward C.

The PLL calculator app in the files section may help.
