INSTRUKTIONSSTYRSYSTEM FOR INMATNING AV ADRESSNYCKLAR I ETT ADRESSNYCKELREGISTER |
摘要 |
The disclosure describes instruction operated controls for loading or storing address key values into or from one or more address key register sections in a key-register-controlled addressing system. The controls load or store one or all key register sections of an address key register (AKR) in a processor from or to a word in either a main memory or a general purpose register (GPR). Both the load or store controls are operated by the same instruction format, in which one field indicates whether the operation is to be a load or store of the designated AKR section(s). Another field designates one AKR section, or all AKR sections, which are to be loaded or stored. A still further field designates whether the operation is to be from or to main memory or a GPR. The disclosure provides circuits which operate with microcode to perform these operations. |
