AMBA High-performance Bus
The Arm Advanced Microcontroller Bus Architecture (AMBA) is an open-standard, on-chip interconnect specification for the connection and management of functional blocks in system-on-a-chip (SoC) designs. It facilitates development of multi-processor designs with large numbers of controllers and components with a bus architecture. Since its inception, the scope of AMBA has, despite its name, gone far beyond microcontroller devices. Today, AMBA is widely used on a range of ASIC and SoC parts including applications processors used in modern portable mobile devices like smartphones. AMBA is a registered trademark of Arm Ltd. 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. In 2003, Arm introduced the third generation, AMBA 3, including Advanced eXtensible Interface (AXI) to reach even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Functional Unit
In computer engineering, an execution unit (E-unit or EU) is a part of a processing unit that performs the operations and calculations forwarded from the instruction unit. It may have its own internal control sequence unit (not to be confused with a CPU's main control unit), some registers, and other internal units such as an arithmetic logic unit, address generation unit, floating-point unit, load–store unit, branch execution unit or other smaller and more specific components, and can be tailored to support a certain datatype, such as integers or floating-points. It is common for modern processing units to have multiple parallel functional units within its execution units, which is referred to as superscalar A superscalar processor (or multiple-issue processor) is a CPU that implements a form of parallelism called instruction-level parallelism within a single processor. In contrast to a scalar processor, which can execute at most one single in ... design. The si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SDRAM
Synchronous dynamic random-access memory (synchronous dynamic RAM or SDRAM) is any DRAM where the operation of its external pin interface is coordinated by an externally supplied clock signal. DRAM integrated circuits (ICs) produced from the early 1970s to the early 1990s used an ''asynchronous'' interface, in which input control signals have a direct effect on internal functions delayed only by the trip across its semiconductor pathways. SDRAM has a ''synchronous'' interface, whereby changes on control inputs are recognised after a rising edge of its clock input. In SDRAM families standardized by JEDEC, the clock signal controls the stepping of an internal finite-state machine that responds to incoming commands. These commands can be pipelined to improve performance, with previously started operations completing while new commands are received. The memory is divided into several equally sized but independent sections called ''banks'', allowing the device to operate on a memor ...

System On A Chip
A system on a chip (SoC) is an integrated circuit that combines most or all key components of a computer or Electronics, electronic system onto a single microchip. Typically, an SoC includes a central processing unit (CPU) with computer memory, memory, input/output, and computer data storage#Secondary storage, data storage control functions, along with optional features like a graphics processing unit (GPU), Wi-Fi connectivity, and radio frequency processing. This high level of integration minimizes the need for separate, discrete components, thereby enhancing Performance per watt, power efficiency and simplifying device design. High-performance SoCs are often paired with dedicated memory, such as LPDDR, and flash storage chips, such as Universal Flash Storage, eUFS or eMMC, which may be stacked directly on top of the SoC in a Package on a package, package-on-package (PoP) configuration or placed nearby on the motherboard. Some SoCs also operate alongside specialized chips, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CoreConnect
CoreConnect is a microprocessor Bus (computing), 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 Multi-core (computing), cores within standard and custom SoC designs. As a standard SoC design point, it serves as the foundation of IBM or non-IBM devices. Elements of this architecture include the processor local bus (PLB), the on-chip peripheral bus (OPB), a bus bridge, and a device control register (DCR) bus. High-performance peripherals connect to the high-Bit rate, bandwidth, low-Latency (engineering), latency PLB. Slower peripheral cores connect to the OPB, which reduces traffic on the PLB. CoreConnect has bridging capabilities to the competing Advanced Microcontroller Bus Architecture, 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-developme ...

OpenCores
OpenCores is a community developing digital open-source hardware through electronic design automation (EDA), with a similar ethos to the free software movement. OpenCores hopes to eliminate redundant design work and significantly reduce development costs. A number of companies have been reported as adopting OpenCores IP in chips,Andrew Orlowski, "Flextronics demos open source chips", ''The Register'', 12 December 2003/ref> or as adjuncts to EDA tools. OpenCores is also sometimes cited as an example of open source in the electronics hardware community. OpenCores has always been a commercially owned organization. In 2015, its core active users established the independent Free and Open Source Silicon Foundation (FOSSi Foundation), and created another directory on the librecores.org website as the basis for all future development, independent of commercial control. It has been shut down to redirect to a post on the FOSSi Foundation website seven years later in favor of a simple web ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wishbone (computer Bus)
The Wishbone Bus is an open source hardware computer bus intended to let the parts of an integrated circuit communicate with each other. The aim is to allow the connection of differing cores to each other inside of a chip. The Wishbone Bus is used by many designs in the OpenCores project. Wishbone is intended as a "logic bus". It does not specify electrical information or the bus topology. Instead, the specification is written in terms of "signals", clock cycles, and high and low levels. This ambiguity is intentional. Wishbone is made to let designers combine several designs written in Verilog, VHDL or some other logic-description language for electronic design automation (EDA). Wishbone provides a standard way for designers to combine these hardware logic designs (called "cores"). Wishbone is defined to have 8, 16, 32, and 64-bit buses. All signals are synchronous to a single clock but some slave responses must be generated combinatorially for maximum performance. Wishbon ...
