System Architecture
DEFINITIONS
CPU: a collection of billions of electronic switches that processes data, execute and control the operations of a computer
-
-
Registers: small memory locations within the CPU that temporarily store data and can be accessed quickly
-
-
memory address register: stores the address of the location in memory for the data to be fetched or sent to
-
-
CPU CONFIGURATION
-
-
-
Cores each core can fetch and execute instructions independently so a multiple core processer can handle several instructions at the same time.
-
-
Cache: located between the main memory and the CPU. Use to hold data that needs to be accessed quickly. Accessing cache is faster than accessing main memory.
FIRMWARE
Hardware: the physical parts that make up a computer, such as a keyboard and mouse
-
-
e.g) operating systems, internet browsers
Embedded Systems
-
cheaper, smaller, reliable/less tasks, lower power consumption
