x4 High Performance 8-bit RISC Microcontroller
The DRPIC1655X is a low-cost, high-performance, 8-bit, fully static soft IP Core, intended to operate with fast, 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 core market. DCD’s IP Core is software-compatible with 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 instruction fetch and memory transfers can be overlapped by a 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 DRPIC1655X architecture is 4 times faster compared to the standard architecture. Most instructions are executed within 1 system clock period, except the instructions which operate directly on a PC (GOTO, CALL, RETURN) program counter. This situation requires the pipeline to be cleared and subsequently refilled. This operation takes an additional one clock cycle. The DRPIC1655X 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 crucial. The DRPIC165X is delivered with a fully automated test bench and a complete set of tests, allowing easy package validation at each stage of the SoC design flow. Each of DCD’s PIC Cores has built-in support for a proprietary Hardware Debug System called DoCD™. It is a real-time hardware debugger that provides debugging capability of a whole System-on-Chip (SoC). Unlike other on-chip debuggers, the DoCD™ allows non-intrusive debugging of a running application. It can halt, run, step into or skip an instruction, and read/write any contents of the microcontroller, including all registers, and SFRs, including user-defined peripherals, data, and program memories.

Power of Innovation is our primary target. That’s why our R&D focuses on every IP Core detail. As a result of that concern, some unique solutions were born. One of them is the PIC on-Chip Debugger (DoCD™) which is a complete debugging system, dedicated for DCD’s DFPIC16XXX/DRPIC16XXX Microcontroller Cores.Read more
