| 31. | Some architectures include other stages such as memory access.
|
| 32. | This requires a lot of complex circuitry to generate the memory accesses and coordinate them.
|
| 33. | The Display List and the display data are written into direct memory access ( DMA ).
|
| 34. | I / O operations can slow memory access if the address and data buses are shared.
|
| 35. | On FreeBSD, it is also possible to debug using Firewire direct memory access ( DMA ).
|
| 36. | ;Rematerialization : Rematerialization recalculates a value instead of loading it from memory, preventing a memory access.
|
| 37. | This ensures that high code density is achieved, while minimizing memory accesses to help conserve power.
|
| 38. | Thus any straightforward virtual memory scheme would have the effect of doubling the memory access time.
|
| 39. | However, there is a high memory access latency.
|
| 40. | Scheduling memory accesses requires explicit, spare registers.
