Processor Functions
The NPE is a hardware-multi-threaded processor engine that is used to accelerate
functions that are difficult to achieve high performance in a standard RISC processor.
Each NPE is a 133.32 MHz (which is 4 * OSC_IN input pin) processor core that has self-
contained instruction memory and self-contained data memory that operate in parallel.
In addition to having separate instruction/data memory and local-code store, the NPE
supports hardware multi-threading with support for multiple contexts. The support of
hardware multi-threading creates an efficient processor engine with minimal processor
stalls due to the ability of the processor to switch contexts in a single clock cycle, based
on a prioritized/preemptive basis. The prioritized/preemptive nature of the context
switching allows time-critical applications to be implemented in a low-latency fashion —
which is required when processing multi-media applications.
The NPE also connects several hardware-based coprocessors that are used to
implement functions that are difficult for a processor to implement. These functions
include:
These coprocessors are implemented in hardware, enabling the coprocessors and the
NPE processor core to operate in parallel.
The combined forces of the hardware multi-threading, local-code store, independent
instruction memory, independent data memory, and parallel processing allows the Intel
