The type of memory to be used and the method of interfacing with the microprocessor must be chosen during the early design stages. This article describes a number of memory interface examples using the Signetics 2650 microprocessor. Detailed information about these memory systems can be found in ...
In the grand scheme of things, remember we have this thing here called the system controller, and actually, the system controller, it interfaces with the cache as well.The processor ideally does its interfacing with cache, and when it needs a command, it first looks in cache and if cache ...
appear to have been executed in the order specified, with all out-of-order execution hidden to the programmer – however in multi-threaded environments (or when interfacing with other hardware via memory buses) this can lead to problems. To avoid problems,memory barrierscan be used in these ...
(CLBs). Each LE can be configured to perform combinational or sequential functions.Figure 5.59shows a generalblock diagramof an FPGA. The LEs are surrounded byinput/output elements(IOEs) for interfacing with the outside world. The IOEs connect LE inputs and outputs to pins on the chip ...

Microprocessor EPROM application ROM Timing Memories and functions ROMs are actually combinational devices, not sequential ones! You can store arbitrary data into a ROM, so the same address will always contain the same data. You can think of a ROM as a combinational circuit that takes an address...
In contrast, the DS5001FP provides a non-multiplexed, 15-bit bytewide address bus (pins BA0-BA14), four chip enables, and an 8-bit bytewide data bus (pins BD0-BD7) for interfacing to bytewide memories. Consequently, application software can address up to 64K×8 of program memory and...
A serial pipeline processing system of the present invention comprises a single two-wire bus used for carrying unique and specialized interactive interfacing tokens, in the form of control tokens and data tokens, to a plurality of adaptive decompression circuits and the like positioned as a reconfigu...
PURPOSE: To provide a security memory card containing a microprocessor on one semiconductor chip and one or more nonvolatile addressable memory chips. ;CONSTITUTION: Both a microprocessor chip and a nonvolatile memory chip are connected to an internal card bus and addresses, data, and control infor...
I/O interface 1040 may include one or more interface components through which a user interacts with system 1000 (e.g., video, audio, and/or alphanumeric interfacing). Network interface 1050 provides system 1000 the ability to communicate with remote devices (e.g., servers, other computing ...
