DCD's HDLC/SDLC controller aims telecommunication

Bytom -- December 2nd, 2013 -- Digital Core Design, an IP Core provider and a System-on-Chip design house, has introduced its latest soft IP Core, the DHDLC. It’s been designed to control HDLC/SDLC transmission frame and optimized for great variety of 8, 16 and 32-bit MCUs. Same as all other DCD’s IP Cores, the DHDLC is a technology independent design, therefore can be implemented in both, ASIC and FPGA.

The DHDLC IP core is used for controlling HDLC/SDLC transmission frame, no matter if it’s 8-, 16- or 32-bit microcontroller. The greatest advantage of this IP Core is the possibility to save MCU time wasted for handling HDLC/SDLC features, like bit stuffing, address recognition and CRC computation. To enable even more productivity, the DHDLC has an implemented FIFO buffer, for both receiver and transmitter. – We’ve designed the DHDLC IP Core, because… our customers asked us to do it so many times – explains Jacek Hanke, DCD’s CEO. Configurable core parameters and adjustable CPU interface are a must be in this project.

The DHDLC IP Core is fully synchronous with one clock domain design. All parameters are configurable by CPU, but there is also an another option. One can set all the parameters by modification constants in a source file. Thanks to it, there’s no need to waste silicon resources for unused features and constant settings.

DHLC’s Key Features:

Two separate receiver and transmitter interfaces.
Two separate, configurable FIFO buffers for receiver and transmitter
Bit stuffing and unstuffing
Address recognition for receiver and address insertion for transmitter
Two or one byte address field
RC-16 and CRC-32 computation and checking
Collision detect
Byte alignment error detection
Programmable number of bits for idle detection
NRZI coding support
Shared flags, shared zeros support
Pad fill with flags option
Transmitter clock generation
8-bit, 16-bit, 32-bit CPU interface
Interrupt output for handling control flags and FIFOs’ filling
Configurable core parameters
