A memory system for a digital processor device having a 16-bit bidirectional bus with multiplexed addresses and data employs separate memory devices for the high order and low order data bytes. When less than 64 K words of memory are used, there are unused address lines in the bus. A ...
The remaining three address line outputs from the microprocessor could be left unconnected. However, in this case, to ensure that a particular location in the memory can only be accessed by a unique address, a system ofabsolute decodingis employed. Address linesA18,A19andA20are connected to an...

In subject area:Engineering Memory arrays, as the name implies, are simply solid-state memory devices that have been packaged in a format that allows an image to be placed on the area that is the usual memory array. From:Reference Data for Engineers (Ninth Edition),2002 ...
A microprocessor (100) having a selectable byte-wide PROM interface (104) is disclosed. Instructions can be executed from byte-wide or word-wide (multi-byte-wide) devices, without external glue logic. A selectable byte-gathering feature is provided. Access times for each byte (or word) are ...
It does basic calculator like things—adding, subtracting, multiplying, and dividing values stored in the computer’s memory. Computer programs tell the microprocessor what to do, which is how everything works inside a PC. Other terms for the microprocessor include the processor, the central ...
While ROM itself isn’t typically upgraded like RAM, some devices allow for firmware updates which effectively update the data stored in ROM. This process is usually managed by the device’s operating system or manufacturer-provided tools. In some cases, such as with some embedded systems, the...
memory devices are highly pipelined. Attributes of the memory hierarchy described above are all structured to try to ensure that the application does not directly experience the latency of a DRAM transaction. To that end, in addition to thecache structure, some platforms have pre-fetchers. A pre...

Computer peripherals are devices used to input information and instructions into a computer for storage or processing and to output the processed data. In addition, devices that enable the transmission and reception of data between computers are often classified as peripherals. Input devices A plethora...
