I was the pilot flying the MASHH RNAV arrival into MEM. Approaching MASHH Intersection I realized the automation was not sufficiently slowing the aircraft for the published speed of 230 KTS at FASOP Intersection. I believe I may have overridden my speeds at the fixes with an earlier tactical speed adjustment. I deselected profile mode and extended the speed brake and slowed the descent to reduce the speed. In doing so I also reduced my rate of descent and was approximately 300 feet high crossing FASOP and about 18 knots fast. I kept the speed brake extended and met both speed and altitude constraints approximately 1.5 to two miles past FASOP.There was no loss of separation vertically or horizontally with any other traffic that we were aware of. These were the circumstances to the best of my knowledge and recall. My primary focus was getting the aircraft on altitude and speed not focusing on the distances once I saw the need to make a correction. Earlier intervention with the automation [might have helped]. Also; I could have adjusted the altitudes and speeds more conservatively in the FMS to ensure the parameters of these new arrivals are met.
An A300 flight crew was unable to comply with the crossing speed and altitude restrictions at MASHH Intersection on the MASHH RNAV STAR at MEM.
