A memory controller, also known as memory chip controller (MCC) or a memory controller unit (MCU), is a digital circuit that manages the flow of data going to and from a computer's main memory. [ 1 ] [ 2 ] When a memory controller is integrated into another chip, such as an integral part of a microprocessor , it is usually called an integrated ...
This is an enhanced southbridge for the remaining peripherals—as traditional northbridge duties, such as memory controller, expansion bus (PCIe) interface and even on-board video controller, are integrated into the CPU die itself (the chipset often contains secondary PCIe connections though).
An application-specific integrated circuit (ASIC / ˈ eɪ s ɪ k /) is an integrated circuit (IC) chip customized for a particular use, rather than intended for general-purpose use, such as a chip designed to run in a digital voice recorder or a high-efficiency video codec. [1]
The Platform Controller Hub (PCH) is a family of Intel's single-chip chipsets, first introduced in 2009. It is the successor to the Intel Hub Architecture , which used two chips–a northbridge and southbridge , and first appeared in the Intel 5 Series .
Thus, the northbridge became the Memory Controller Hub (MCH) or if it had integrated graphics (e.g., Intel 810), the Graphics and Memory Controller Hub (GMCH). Other ICH features include: PCI Rev 2.2 compliant with support for 33 MHz PCI operations. Advanced Configuration and Power Interface (ACPI) Support; Integrated IDE controller for Ultra ...
With microcontrollers (entire computer systems integrated onto single chips), the use of different memory technologies for instructions (e.g. flash memory) and data (typically read/write memory) in von Neumann machines is becoming popular. The true distinction of a Harvard machine is that instruction and data memory occupy different address ...
IHA is now considered obsolete and no longer used, being superseded by the Direct Media Interface architecture. The Platform Controller Hub (PCH) providing most of the features previously seen in ICH chips while moving memory, graphics and PCI Express controllers to the CPU, introduced with the Intel 5 Series chipsets in 2009.
A finite-state machine with data path (FSMD) is a mathematical abstraction which combines a finite-state machine, which controls the program flow, with a data path.It can be used to design digital logic or computer programs.
