This is designed for microcontrollers, using on-chip flash memory for program storage and running without an MMU ( memory management unit ).
12.
Early models of PIC had read-only memory ( ROM ) or field-programmable EPROM for program storage, some with provision for erasing memory.
13.
However, limited program address space and lack of easy program storage made calculator gaming a rarity even as programmables became cheap and relatively easy to obtain.
14.
The 6502 offered the right combinations of features, performance and price that made a console using ROM cartridges for program storage practical for the first time.
15.
The F3851 is the program storage unit containing 1K ROM . It is programmed in manufacturing using a mask that could be specified by the customer of Fairchild.
16.
The RAM adapter contains 32 kilobytes ( KB ) of RAM for temporary program storage, 8 KB of RAM for tile and batteries or the supplied AC adapter.
17.
This memory served for both for I / O buffering and program storage, but the execution units were shared by 10 PPs, in a configuration called the Barrel and slot.
18.
The BASIC interpreter also acted as a primitive operating system, providing file handling capabilities for program storage using RAM, cards, or cassettes / diskettes ( via HP-IL ).
19.
This technique may be more difficult to implement in multitasking systems using shared program storage ( the interrupt may occur on a different thread, requiring resurrection of the original instruction for that thread ).
20.
Early motor program theories did not adequately account for evidence illustrating the influence of feedback for the modification of ongoing movement while providing a suitable explanation of motor programs storage or application in novel movement.
