The Advanced eXtensible Interface (AXI) is an on-chip communication bus protocol and is part of the Advanced Microcontroller Bus Architecture specification (AMBA). [ 1 ] [ 2 ] AXI had been introduced in 2003 with the AMBA3 specification.
In its second version, AMBA 2 in 1999, Arm added AMBA High-performance Bus (AHB) that is a single clock-edge protocol. In 2003, Arm introduced the third generation, AMBA 3, including Advanced eXtensible Interface (AXI) to reach even higher performance interconnect and the Advanced Trace Bus (ATB) as part of the CoreSight on-chip debug and trace ...
The algorithmic state machine (ASM) is a method for designing finite-state machines (FSMs) originally developed by Thomas E. Osborne at the University of California, Berkeley (UCB) since 1960, [1] introduced to and implemented at Hewlett-Packard in 1968, formalized and expanded since 1967 and written about by Christopher R. Clare since 1970.
An often cited example is the control of the thickness of cheese slices after an AXI determined the distribution and position of 'holes' inside the cheese block. (to ensure consistent total package weight). Recently, automated methods have been developed for X-ray inspection of food passing by on a conveyor belt. [5] [6] [7]
A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1] They are heavily used in engineering in hardware design , electronic design , software design , and process flow diagrams .
Apple M1 system on a chip A system on a chip from Broadcom in a Raspberry Pi. A system on a chip or system-on-chip (SoC / ˌ ˈ ɛ s oʊ s iː /; pl. SoCs / ˌ ˈ ɛ s oʊ s iː z /) is an integrated circuit that integrates most or all components of a computer or electronic system.
When a processor writes on a shared cache block, all the shared copies of the other caches are updated through bus snooping. This method broadcasts a write data to all caches throughout a bus. It incurs larger bus traffic than write-invalidate protocol. That is why this method is uncommon. Dragon and firefly protocols belong to this category ...
The Block Diagram Editor is the primary graphical user interface and is supported with customizable library blocks of hardware, software, and communication resources. Graphical viewers can be placed in the model for real-time viewing or for saving offline analysis. VisualSim has taken SystemC modeling to a higher level of abstraction.
