MIPS Technologies (Nasdaq: MIPS) was supposed to present a full fourth-quarter earnings release this week. Instead, we had to settle for a preliminary report with revenue of $38.4 million -- and the rest to be presented Aug. 15.

The semiconductor technology researcher blamed the delay on the finalization of "certain expense accruals." Given that the report covers a period ending on June 30, the company already had ample time to calculate whatever accounting artifacts it needed to. I'll be very interested to hear more about these as-yet-undisclosed accruals, and why they demanded such extraordinary measures.

The two companies are locked in mortal combat over key markets such as mobile computing and chips destined for set-top boxes. ARM is crushing the mobile market so far and powers just about every smartphone and tablet on the market, save a couple of obscure MIPS-based models from China.

Mighty Intel (Nasdaq: INTC) also wants a toehold in tablet computing, but its Atom processors won't really matter in this segment until Microsoft (Nasdaq: MSFT) releases its much-vaunted Windows 8 software this fall. And even then, Mr. Softy made the Windows tablet platform compatible with ARM chips as well.

MIPS didn't provide any detail whatsoever to shine a light on this epic struggle. For what it's worth, analysts were looking for sales of $40.4 million yielding adjusted earnings of $0.34 per share. Even the somewhat disappointing revenue figure is far stronger than the year-ago period's $17.6 million, and MIPS only managed earnings of $0.04 per share that time. So the company is moving in the right direction, but the delay and revenue miss still tell us that something went wrong here.
