Description

Gutes Exemplar; Einband stw. leicht nachgedunkelt; R�ckdeckel m. kl. Preisschild. - Englisch. - Der Motorola 68000 ist ein 1979 eingef�hrter CISC-Prozessor aus der 68000er-Familie von Motorola (sp�r Freescale, heute NXP). Er besitzt intern 32-Bit-Register, einen mit 32 Bit adressierten linearen Adressraum, davon 24 Bit extern verf�gbar, acht 32-Bit-Datenregister, neun 32-Bit-Adressregister, ein 16-Bit-Statusregister sowie einen 16-Bit-Datenbus. . (wiki) // Take your next step in personal Computing. Lionel Fleetwood writes in a pleasant, easy-to-understand way, even with a topic as complex as the 68000 processor. The 68000, and its derivatives, is fast-becoming a popul�device used in the Sinclair QL and Apple Macintosh Computers. It has a 32-bit address bus, 32-bit data and address registers and a dock that runs at speeds of up to 12.5 MHz. With that kind of specification, demand for 68000 programmers is set for explosive growth-so now is the time to learn as much as you can, as quickly as you can, about this processor. If you have some knowledge of a high level language, such as BASIC, you'll soon settle down with this expertly-written book. It gives you a firm grounding in assembly language programming and shows you how to apply your knowledge to real-world projects. � (Verlagstext) // INHALT : .
