Accurate Timer & Cadence Meter

Hi,

I'm considering undertaking a project which requires a timer accurate to
1/10sec. It should be capable of start, stop and reset only. PCB space is at
a premium, so I wondered if anyone could suggest an IC which does this,
using minimal additional components. I intend to interface to a series of
7-seg displays.

The second part of the project is a cadence meter, I'd like to have a
reading in Hz. My input signal consists of a series of pulses of slightly
varied length in the range of 10-40 Hz. Again, I would like to interface
this to a 7 seg display. I have several ideas on how i could construct this,
however I wondered what people's experience is on the matter. Most
importantly, I would like to generate the first reading within 5-10 seconds,
no more!

Many thanks in advance,

Tim
