"In a DMA while the data is transferred between the memory and the device, if it is stopped or interrupted by any other device like CPU, it would result into a Data loss, since DMA doesnt have a program counter unlike CPU which stores it current position. In CPU if it is interrupted, it suspends it s operation without any data loss. Hence DMA has a higher priority than CPU."

My point is really that in the summary title line TPL used the phrasing is "DMA CPU" whereas in the text they wrote "circuit". The Judge sided with T3's construction which used "CPU" not circuit.

That seems to me to mean that his construction specifically requires a CPU. If control is by circuitry other than a CPU then I infer that there is no infringement.

Time will tell, and perhaps this specific claim and its contruction is not critical in the overall scheme of things.
