Protected through year of 2015, these patents protect techniques used in designing microprocessors, Digital Signal Processor (DSPs), embedded processors and System-on-Chip (SoC) implementations. The three most widely recognized patents in the portfolio are described below:
- US'336: Clocking CPU and I/O Separately
The MMP Portfolio is
not limited to "high speed" microprocessors. In fact, during the past
year of intense study of hundreds of various microprocessor designs, no
correlation at all has been found between the speed of a microprocessor
and the application of US'336. Use of US'336 is prevalent across most
microprocessors from low speed microcontrollers to sophisticated
systems on chips. Advertised advantages include: cost reduction,
instant-on execution, failsafe operation, EMI reduction, and power
savings. It is a modern requirement from a design for test ("DFT")
perspective.
- US'584: Multiple Instruction Fetch
Multiple Instruction
Fetch architectures are the norm in environments where limiting power
consumption is critical; e.g. portable products. Various techniques can
be employed to achieve the Multiple Instruction Fetch, and marketing
terminology includes "VLIW," "SIMD," "MIMD", "Superscalar," etc.
- US'148: On-Chip Oscillator and Embedded Memory
Shares the on-chip
oscillator feature with US'336, in addition to memory covering more
than majority of chip. Also includes claims pertaining to multiple CPU,
array or cell implementations. The vast majority of the SoC and flash
microcontroller products are affected.
