DRPIC166X
High Performance Configurable
8-bit RISC Microcontroller
ver 2.15
OVERVIEW
The DRPIC166X is a low-cost, high per-
formance, 8-bit, fully static soft IP Core,
dedicated for operation with
fast
(typically on-
chip) dual ported
memory.
The core has been
designed with a special concern about
low
power consumption.
DRPIC166X soft core is software-
compatible with the industry standard
PIC16C6X. It implements an
enhanced
Harvard
architecture
(i.e.
separate
instruction and data memories) with
independent address and data buses. The 14
bit program memory and 8-bit dual port data
memory allow instruction fetch and data
operations to occur simultaneously. The
advantage of this architecture is that
instruction fetch and memory transfers can be
overlapped by multi stage pipeline, so that the
next instruction can be fetched from program
memory while the current instruction is
executed with data from the data memory.
The DRPIC166X architecture is
4 times
faster
compared to standard architecture. So
most instructions are executed within
1
system clock period,
except the instructions
which directly operates on program counter
PC (GOTO, CALL, RETURN), this situation
require the pipeline to be cleared and
subsequently refilled. This operation takes
additional one clock cycle.
The DRPIC166X Microcontroller fits
perfectly in applications ranging from high-

speed automotive and appliance motor control
to low-power remote transmitters/receivers,
pointing devices and telecom processors.
Built-in power save mode make this IP perfect
for applications where power consumption is
critical.
DRPIC166X is delivered with
fully automated
testbench
and
complete set of tests
allowing easy package validation at each
stage of SoC design flow
