A status register, flag register, or condition code register (CCR) is a collection of status flag bits for a processor.Examples of such registers include FLAGS register in the x86 architecture, flags in the program status word (PSW) register in the IBM System/360 architecture through z/Architecture, and the application program status register (APSR) in the ARM Cortex-A architecture.
Personal support worker (PSW) is the title for a similar type of health worker in Canada. Personal support work is unique among health care professions in that the scope of a PSW's duties does not extend beyond what the client could do him/herself if the client were physically and cognitively able.

Bellmac 32 has sixteen 32-bit registers. Three of these (ISP, PCBP, PSW) are privileged, used to support the operating system and can be written only when the microprocessor is in kernel mode. There are three other registers (SP, AP, FP) that are used by some instructions as stack pointers.
Level 2 – PSW with product samples and limited supporting data. Level 3 – PSW with product samples and complete supporting data. Level 4 – PSW and other requirements as defined by the customer. Level 5 – PSW with product samples and complete supporting data available for review at the supplier's manufacturing location. Complete ...
This is often known as "shift-left" or "pre-silicon support" in the hardware development field. A full system simulator or virtual platform for the future hardware typically includes one or more instruction set simulators. To simulate the machine code of another hardware device or entire computer for upward compatibility.
It continues today as PSW Science. Since 1887, the Society has met regularly in the assembly hall of the Cosmos Club. In the Club's present location since 1951, the assembly hall is now called the John Wesley Powell auditorium. Meetings are roughly every other Friday, except in the summer. Meetings are free and open to the public.
