A field programmable gate array (FPGA) utilizes an array of logic blocks, which can be configured by the user. The term “field programmable” implies that the device is programmable outside the factory where it is produced.
The internal architecture of … Read More
The architecture of a programmable read only memory (PROM) allows the user to use the hardware in implementing an arbitrary combinational function of a given number of inputs. When utilized as a memory device, n inputs of the ROM (called … Read More
Since digital data is usually stored in the form bits, digital memory devices such as the computer random access memory (RAM) requires a way for storing and switching between the two binary states. A flip-flop is a sequential logic device … Read More
Parallel processing, in which applications are partitioned into multiple tasks that are executed concurrently by multiple processors is used for high-throughput needs where even the single fastest computer cannot be good enough.
Multiple processor system architectures differ widely in … Read More
The Pentium processors have a 64-bit data bus which is a major advancement in personal computer CPU design. In actual fact, the Pentium family of processors has its origins in the Intel 486 processor, and has similar instruction set with … Read More
A computer system uses memory elements for storing program instructions, data, and other information. From the perspective of the instruction set, a memory is an array of words, each identified by a unique address that indicates its location within the … Read More
Microprocessors perform various basic operations that include data transfer instructions, arithmetic instructions, logic instructions, control transfer instructions and machine control operations. This set of commands (instructions set) used to control the functions of a microprocessor is specific to a given … Read More
Processor architecture can be classified as one of the following four architectures:
In the accumulator-based processor architecture, illustrated above, instructions … Read More
The microprocessor is typically referred to as the central processing unit (CPU). It is the part of the processor system which processes the data, fetching instructions from memory, decoding them and executing them. The internal structure (architecture) – depends on … Read More
There are two basic primary architectures used for mapping special function registers into memory space. In the first type of arrangement, I/O space and memory space are separated as illustrated in Figure 1.0. The I/O devices have a separate address … Read More
