CHEVRON SHAPED DECKING

Use a sliding mitre saw.

It won't work for the first half because the boards have to be cut to fit halfway across a joist - unless you have a double thickness joist.

If the edges of the deck abut to a building or wall then both ends have to be cut at an angle prior to fixing, if not you could lop them off afterwards.

Cheap mitre saw with enough capacity would help a lot.

Get the 'centre' board sorted first and calculate from there.

If the angles are all cut at 45 degrees, then they'll match up fine at 90 degrees. It's measuring the correct length to include the angles that's the bugger.

You fit all the boards for the first half and then simply run the circular saw across them along the line of the middle of the joist, setting the depth so it doesn't cut into the joist. Where's the requirement for a double thick joist?

A lot better to measure and cut each board accurately though.

Or, lay the second half temporarily in place ontop of the first half then run the saw through them both as you say to the depth where it doesn't cut the joist. Then unscrew second half remove waste below paint cut ends re-screw in and you should have consistent gap of the width of the saw blade over all the joins. Use a straight edge as a jig and you will have a perfect job!
