AMBA was introduced by Arm in 1996. The first AMBA buses were the Advanced System Bus (ASB) and the Advanced Peripheral Bus (APB). In its second version, AMBA 2 in 1999, Arm added AMBA High-performance Bus (AHB) that is a single clock-edge protocol.
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.
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.
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.
CoreConnect is a microprocessor bus-architecture from IBM for system-on-a-chip (SoC) designs. It was designed to ease the integration and reuse of processor, system, and peripheral cores within standard and custom SoC designs.
This new bus was named the Extended (or Enhanced) Industry Standard Architecture, or "EISA", while the older AT bus had already been renamed Industry Standard Architecture, or "ISA". [8] This provided virtually all of the technical advantages of MCA, while remaining compatible with existing 8-bit and 16-bit cards, and (most enticing to system ...
Particularly, the advent of the 80386 processor in 1985 and its capacity for 32-bit transfers (although great improvements in the efficiency of address calculation and block memory moves in Intel CPUs after the 80186 meant that PIO transfers even by the 16-bit-bus 286 and 386SX could still easily outstrip the 8237), as well as the development ...
QSPI bus controller supports up to 16 MB of external flash memory; DMA controller, 12 channel, 2 IRQ; AHB crossbar, fully-connected; On-chip programmable low-dropout regulator (LDO) to generate core voltage; Two on-chip PLLs to generate USB and core clocks; 30 GPIO pins, of which four can optionally be used as analog inputs; Peripherals:
