Overview

The multi-channel Stream Direct Memory Access (SDMA) controller IP core provides high bandwidth direct memory access between memory and any IP peripherals with an AXI4-Stream interface for up to 16 channels.

The SDMA IP utilities a dedicated Write and Read circular buffer structure for data and descriptor(s) for each DMA channel, which helps in offloading data movement tasks from the Central Processing Unit (CPU) in processor-based systems.

Configuration of status and management registers are accessed through an AXI4-Lite interface. Control and Status streaming interfaces are used for sending/receiving user application data. Interrupts are available to indicate error and completion events.

How Time Sensitive Networking powers the Software Defined Vehicle

Software-Defined Vehicles (SDVs) are turning cars into distributed real-time computing platforms. Instead of dozens of standalone ECUs connected by a tangle of legacy field buses, we now see zonal controllers aggregating local I/O, centralized compute platforms running safety, mission critical software, and a service-oriented middleware layer stretching across the vehicle.

Seize the Ethernet TSN Opportunity

The following sections will take a look at the major Ethernet performance issues and how the extensions address those shortcomings. This will be followed by an overview of the applications of TSN for 5G, industrial automation, automotive invehicle communications and avionics. The paper will conclude with a description of Ethernet TSN solutions offered by Comcores.

DMA IP Integration

There are many IP’s today . These IP’s can be simple IP’s like Timer to complex IP’s like Accelerators. In Most of the cases IP’s are Integrated in standard way. There are cases where you have the option of Integrating it differently. This goes un-noticed or unable to be implemented due to time constraints. One such IP that would be discussed in this paper is DMA . This paper tries to explain idea of Integrating Direct Memory access(DMA) and Interrupt Control Unit(ICU) differently but final implementation requires some changes in IP. There is a possibility that alternate design explained below may be already implemented.
