Logical Versus Physical Memory Addresses
Computers use logical and physical addresses to access memory locatiuons. The CPU generates logical addresses. At run-time the Memory Management Unit (MMU) maps logical addresses to physical addresses. More ...
Network on a Chip (NoC)
NoC (Network on a Chip) is a method of placing a much larger number of processors on a multi-core chip. Much like a regular network, NoC has multiple point-to-point data links that are interconnected by routing switches. More ...
Expanding the Resources of Microcontrollers
In some cases it is possible that the internal resources of a microcontroller are insufficient. The solution to these situations is to add external components by creating an expanded microcontroller structure. More ...
The Android Operating System
Android os is similar to Apple ios in that it is a layered stack of software that provides a rich set of frameworks for developing mobile applications. At the bottom of this software stack is the Linux kernal. More ...
Processor Interrupts
An interrupt is a signal to the processor indicating an event has occurred that needs immediate attention. When an interrupt occurs, the processors normal path of execution is interrupted in order to run a routine to service the interrupt requester. More ...
Using the Microcontroller Timers
Timing is an essential function for generating signals with precisely determined duration, or for counting external events. For this reason, a timer subsystem is present in all microcontroller implementations. More ...
Intel's Core i7 Processors
Core i7 is a family of Intel quad core processors, that is, they have four processors on a single silicon chip. All four processor cores and all memory caches, including a 64K L1 cache, a 256K L2 cache, and a shared L3 cache are located on one chip. The memory is also located on the same chip. More ...
The AMD Athlon 64 Processor
AMD's Athlon 64 processor, released in September 2003, was their first 64-bit processor targeted for the workstation market to compete with Intel's Pentium 4. AMD's first 64-bit processor was the Opteron, released earlier in April that same year, targeted for the server market to compete with Intel's Xeon processor. More ...
The Microcontroller Memory Map
a microcontroller is a set of resources. Each resource is identified by one or more addresses in an address space. The memory map is a graphic representation of how the resources are associated with addresses. More ...
Operating System Memory Paging
Paging is a memory management scheme that permits a process's physical address space to be noncontiguous. More ...
Intel's Dual-Core Core i3 Processor
Core i3 is an entry-level 2-core processor using the 32nm Westmere micro-architecture. With a Thermal Design Power (TDP) of 73 watts, the i3-530 is a cool-running chip that doesn't gobble loads of electricity, so those looking for a power-efficient, quiet machine will be happy with it. More ...
Priority CPU Scheduling Algorithm
CPU Scheduling deals with the problem of deciding which of the processes in the ready queue is to be alocated the CPU. There are many different CPU scheduling algorithms. In this article we describe priority CPU scheduling. More ...
