148 Abstract

A microprocessor integrated circuit including a (microprocessor CPU chip) processing unit disposed upon an integrated circuit substrate is disclosed herein. The processing unit is designed to operate in accordance with a predefined sequence of program instructions stored within an instruction register. A memory, capable of storing information provided by the processing unit and occupying a larger area of the integrated circuit substrate than the processing unit, is also provided within the microprocessor integrated circuit. The memory may be implemented using, for example dynamic or static random-access memory. A variable output frequency system clock, such as generated by a ring oscillator, is also disposed on the integrated circuit substrate.

336 Abstract

A high performance, low cost microprocessor system having a variable speed system clock is disclosed herein. The microprocessor system includes an integrated circuit having a central processing unit and a preferred ring oscillator variable speed system clock for clocking the microprocessor. The central processing unit and ring oscillator variable speed system clock each include a plurality of electronic devices of like type, which allows the central processing unit to operate at a variable processing frequency dependent upon a variable speed of the ring oscillator variable speed system clock. The microprocessor system may also include an input/output interface connected to exchange coupling control signals, address and data with the central processing unit. The input/output interface is independently clocked by a second clock (clocking device) connected thereto (with its own separate external circuit such as ram drive, hard drive etc etc etc).

890 Abstract

A high performance, low cost Microprocessor

The 890 is kind of a wrap up of all or at least most of the MMP patents and how they work together to form a high performance microprocessor, Reduced Instruction Set Computer (RISC)

The MMP patents apply to all microprocessor chips with a variable speed clocking device regardless of whether it is a ring oscillator such as the one preferred in the 148 patent or some other method.

The 890 examiner is going over the some of the same territory that was re-examined in the 336 and maybe the 148. He added a few new names and some old ones, but is still saying it was obvious based on a KSR type combination. If that is the case, it could mean trouble for our other patents.

Just my layman opinion.
