I ran a search on the very title of PTSC's patent 5,809,336 "High Performance Microprocessor Having Variable Speed System Clock."

Low and behold, among the returns were a couple of very old sites (1996 - one year after PTSC filled for patent 5,809,336) by ARM (Advanced RISC Machines Ltd) and Digital Semiconductor -- development collaborators of Intel (among many others). In the text it goes on to describe features and functions of this NEW Intel StrongARM SA-110 Microprocessor, the FIRST member of the StrongARM family of high performance, low power microprocessors, the very foundation in which most of their microprocessors are built today. (registered trademarked - NOT patented)

When I first read this information, after I had read PTSC's patent, I swear, it gave me goosebumps -- the best goosebumps I've ever had. There are many notable correlation's, one I particularly like is: excerpt from Intel StrongARM SA 110 Datasheet 1996 --"Clocks --The SA-110 receives 3.68-MHz clock from a crystal based clock generator. The SA-110 uses an internal phase-locked loop (PLL) to multiply the frequency by a veriable multiplier to produce a high speed clock. The high speed clock is then divided internally by a configureable ratio to provide a system clock for synchronous operation. The 3.68MHz oscillator and PLL run constantly in normal and idle mode." Note -- the header for "Clocks" is plural and the clock is "divided" to create a second clock for synchronous operation.

IMO.............ARM is dead in the water and IMO, TPL/PTSC WILL re-visit ARM when the time is right.

Hope this helps and GLTA.
