Used for controlling HDLC/SDLC transmission protocols

The DHDLC IP Core provides versatile support for a widely used HDLC transmission protocol.

Overview

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 this 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. It’s tailored to your project needs and can be provided with: small 8-bit SRAM-like interface, 32-bit full AXI4 slave interface with burst support, AXI4Lite interface, AHB and APB slave interfaces. The optional Frame Status Buffer stores information about frames size and error conditions. Moreover, the size of the receiver and transmitter FIFO buffers is configurable. You can also easily remove unused features before the synthesis process. All that and much more make the DHDLC an ideal solution for very popular higher level protocol implementations like e.g. PPP (Point-to-Point), X.25, V.42, LAB-B, SDLC, ISDN and many others.

Keep Legacy Systems Running with a DO-254 HDLC & SDLC Part Replacement IP Core

One not-so-glamorous but vitally important use for CAST digital IP cores is to replace obsolete parts. Many of our cores can provide the answer if you’re maintaining a legacy system and need to make your own FPGA for a discrete part that was discontinued years ago, or perhaps consolidating a working but ancient board design into a single new chip.

D32PRO, scalable & royalty free 32-bit CPU

D32PRO is one of the newest 32-bit CPUs available on the market. It’s been designed by Digital Core Design, IP Core provider and SoC design house from Poland, responsible e.g. for the world’s fastest or world’s smallest 8051 CPU. DCD launched more than 70 different architectures since 1999, which have been implemented in more than 300 000 000 electronic devices, that’s why one can be sure that quite considerable experience stands behind the D32PRO.
