Contact Provider Request Datasheet

Overview

The D8259 is a soft Core of Programmable Interrupt Controller. It is fully compatible with the 82C59A device. Our efficient IP core can manage up to 8-vectored priority interrupts for the processor. Moreover, you can also program it to cascade and gain up to 64 vectored interrupts. And if it's not enough, you can always get more than 64 vectored interrupts. Just program our IP Core to the Poll Command Mode. The D8259 can operate in all 82C59A modes and it supports all 82C59A features.
 
The D8259 Package includes fully automated testbench. Thanks to complete set of tests, you can easily validate the whole package at each stage of SoC design flow. Same as all DCD's IP Cores, this one's got also a technology independent design, that can be implemented in a variety of process technologies.

Easy migration from Arm to RISC-V: an L110 case study

Last June, we launched the Codasip L110 RISC-V core, introducing the best-in-class solution for power-efficient applications. The L110 is highly competitive in terms of power efficiency and code density. Additionally, it is the first RISC-V core to support easy and risk-free customization while minimizing the verification effort required to bring these customizations to silicon.

A formal-based approach for efficient RISC-V processor verification

In this article, we go through a formal-based, easy-to-deploy RISC-V processor verification application. We show how, together with a RISC-V ISA golden model and RISC-V compliance automatically generated checks, we can efficiently target bugs that would be out of reach for simulation.

SOC Stability in a Small Package

There are some IPs in SOC which are of general use and malfunction on them impacts a entire SOC. We Identified these IPs and analyze impact on SOC due to their malfunction.
