x4 - High Performance 8-bit RISC Microcontroller
The DRPIC166X is a low-cost, high performance, 8-bit, fully static soft IP Core, intended to operate with fast (typically on-chip), dual ported memory. The core has been designed with a special concern about low power consumption, assuring the best power use, price and performance combination available on the IP cores market.
The DRPIC166X soft core is software-compatible with the industry standard PIC 16XXX Microcontrollers. It implements an enhanced Harvard architecture (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 the 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. Most instructions are executed within 1 system clock period, except the instructions which directly operates on PC (GOTO, CALL, RETURN) program counter. This situation requires 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, makes this IP core perfect for applications, where the power consumption aspect is critical.
The DRPIC166X is delivered with fully automated testbench, complete set of tests and DoCD on-chip hardware debugger, allowing easy package validation, at each stage of SoC design flow.
Each of the DCD's PIC Core, has built-in support for the DCD Hardware Debug System, called DoCD . It is a real-time hardware debugger, which provides debugging capability of a whole System on Chip (SoC).
Unlike other on-chip debuggers, the DoCD provides a non-intrusive debugging of running application. It can halt, run, step into or skip an instruction, read/write any contents of microcontroller, including all registers, SFRs, including user defined peripherals and data and program memories.

The good old fashioned PIC microcontrollers are finding their way into new applica-tions like smartphones, gaming peripherals, audio devices and embedded solutions for eg innovative medical devices. Moreover, because the DRPIC166X has upward compatible architecture, it preserves investment in code development. And if it's not enough, let's just mention that DCD's IP Core offers 1.3GHz virtual clock frequency and consumes just 37uW/MHz.
