摘要： An I-fetch control system for a computer includes a control store (30) for storing end op, 1-1, I-2 and return words. A microinstruction decode and control unit (170) responds to end op words to initialize and personalize computer components to facilitate subsequent execution of a high level instruction. The control unit (170), in conjunction with a next address logic (162), selects the next micro-instruction to be executed in response to a high level instruction. The control unit (170) and logic (162) are responsive to 1-1 words to personalize the computer and to select a microinstruction to begin E-phase of a high level instruction. In response to 1-2 control words, the control unit (170) and logic (162) select an operand fetch routine in the control store (30), and write a first E-phase address into a local store (138). The return word gates the first E-phase address from the local store (138) to select a microinstruction in the control store (30) to being E-phase.

摘要： A system and method is provided for testing a computer system main memory during system startup. An initial block of memory (20) is tested and marked as valid or invalid during a startup sequence, with the remaining system memory initially marked as bad. An operating system and applications can be loaded into the initial block and operate normally, and a concurrent process is invoked to test the remaining system memory. This allows the remaining system memory to be tested and marked as valid during normal system operation.

摘要： In a multitasking restricted access data processing system a common compact mechanism is provided for resolving access conflicts automatically irrespective of the category of restriction (read access, modify access or destroy access the type of restriction (shared or exclusive) or the origin of the restriction (user specified or instruction implied). The mechanism operates by testing codewords (34) totally defining the access restriction in relation to a newly required access and currently in force access restrictions in relation to the inhabitants of a chained list (24) associated by a hashed object address form (18) access being denied, held pending until released or a time-out exception occurs or granted, the list appropriate to the transaction being updated accordingly and also updated as restrictions are released.
