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 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 2010, a new revision of AMBA, AMBA4, defined the AXI4, AXI4-Lite and AXI4-Stream protocols.
AMBA AXI, AHB and APB bus interfaces. Memory mapped I/O. 5-stage pipeline. Hardware JTAG debug. While there are many different 16 or 32-bit Soft microprocessor IP cores available, eSi-RISC is the only architecture licensed as an IP core that has both 16 and 32-bit implementations.
AMBA defines two kinds of AHB components: master and slave. A slave interface is similar to programmed I/O through which the software (running on embedded CPU, e.g. ARM ) can write/read I/O registers or (less commonly) local memory blocks inside the device.
Slower peripheral cores connect to the OPB, which reduces traffic on the PLB. CoreConnect has bridging capabilities to the competing AMBA bus architecture, allowing reuse of existing SoC-components. IBM makes the CoreConnect bus available as a no-fee, no-royalty architecture to tool-vendors, core IP-companies, and chip-development companies.
Now APB means advanced peripheral bus,as its name suggest it is a special design bus for to interface peripheral, but it is not as advanced compare with the AHB ,in the bandwidth and all, it is generally used for the like 32 bit interface and component like PCI, SDRAM etc.The AMBA APB is for low-power peripherals. AMBA APB is optimized for ...
SCSI controller (Adaptec AHA-1740) Fast SCSI RAID controller (DPT PM2022) ELSA Winner 1000 Video card for ISA and EISA EISA Network card The Extended Industry Standard Architecture (frequently known by the acronym EISA and pronounced "eee-suh") is a bus standard for IBM PC compatible computers.
Four PCI Express bus card slots (from top to second from bottom: ×4, ×16, ×1 and ×16), compared to a 32-bit conventional PCI bus card slot (very bottom). In computer architecture, a bus (historically also called a data highway [1] or databus) is a communication system that transfers data between components inside a computer or between computers. [2]
