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.

Moving to AMBA® 5? Your AMBA® 4 IP Can Still Come With You

As SoC architectures adopt AMBA® 5 fabrics and components, many proven IP blocks still rely on AMBA® 4 or earlier interfaces. That creates a common integration problem: how do designers connect newer AMBA® 5 system components to existing IP without redesigning the IP or replacing verified blocks?
