Abstract
Computing has always been faced with the choice of optimizing for time (computer power) or space (memory). Real-time computer graphics is most likely the subset of computing that must choose between space and time most effectively. This paper describes in detail the evolved techniques of software memory management used by the Zgrass system to allow a slow (1.7mhz) Z-80 to be the processor for a useful computer animation workstation with at least 300K and up to 1472K bytes of memory. Conclusions will be drawn as to the applicability of these techniques to the new 16-bit microprocessors with memory management.
