What exactly is a bus matrix? I came across the term in ARM cortex M3 specs but couldnt find any proper description. Can someone help?
Hi,
I trying to build the peripheral around Cortex-M0 IP core thorugh AHB-lite system. Right now I have to integrate Cortex-M0 with the DDR2 SRAM (1Gb) through AHB lite.
I searched on internet which shows interfacing only through core generator (MIG…
I see in the documentation site that ARM offers up some bus functional models to simulate both a 32 and a 64 bit AHB bus master in Verilog RTL.
Where do I find these models, and what is the cost?

Hi I was studying the memory system ... and I found three related concepts/topics but I couldn't grasphow these concepts are related to each other and to the AMBA Protocol ... these concepts are : - memory Type - memory Attributes - Monitors and semaphores…
AMBA spec states that 'Master can choose whether to terminate current burst or continue with burst in response to ERROR'.
What does Cortex-M3/M4 do in response to ERROR? Does it continue with burst in response to ERROR in some special cases?
For the SRAM with Cortex M0, does it need to support byte write?
What restrictions do I have with Cortex M0 if the SRAM only support 32-bit write?
Hello,
I try to implement the Cortex-M3 processor on an FPGA via Quartus Prime. I set up the SSE050 Subsystem and tried to connect several peripherals to the board. I want to test the functionality with a uVision project lighting some LEDs. To have access…
The next generation of ARM Cortex-M processors will be powered by a new architecture version called ARMv8-M architecture. This document provides a technical overview of various enhancements in the new architecture, as well as an introduction to the security…
The amount of data we generate is growing exponentially. Gartner has predicted that in 2015 the global mobile data traffic will be a total of 52 billion terabytes, an increase of 59 percent on 2014. It’s a staggering number that is driven not just by…
