The DHDLC IP Core provides versatile support for a widely used HDLC transmission protocol. It manages the bit stuffing process, both address appending and detection. And if it’s not enough, let’s just mention that DCD’s IP Core supports CRC16 and CRC32 computation. Increased system performance and reduced CPU overload is a must be, thanks to the presence of separate receiver and transmitter FIFO buffers, maskable interrupt and DMA interface request. The DHDLC is a fully scalable IP Core, which makes it a perfect solution for both hi-end and deeply embedded projects.
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;
CRC-16 and CRC-32 computation and checking; Collision detection; Byte alignment error detection;
Programmable number of bits for idle detection; NRZI coding support; Shared flags, shared zeroes support;
Pad fill with flags option; Transmitter clock generation; 8-bit, 16-bit, 32-bit CPU interface.
