ARM is Embedded Computing

ARM defines "Embedded Computing" as equipment that performs computing functionality, yet is provided as a "black box"; preloaded applications, limited/no capability to expand hardware functionality and in some cases no screen.
Unlike PCs, system cost, power and form factor constraints often demand the use of Real-Time Operating Systems or Linux, to enable the platform to operate with less system memory.


Modern embedded designs have multiple processors, multiple caches, multiple threads handling graphics and files... and single-threaded file systems that have to handle all that data.
Using flash media, using a multi-threaded file system will eliminate this bottleneck and can give a solid performance improvement by allowing parallel access to files.
My next post will be a short post on the overall savings of the ARM instruction set, which ic based on High Proformanc and the useage of Low Power.
