Program-counter-based (PC-based) prediction techniques have been shown to be highly effective and are widely used in computer architecture design. In this paper, we explore the opportunity and viability of applying PC-based prediction to operating systems design, in particular, to optimize buffer ...
the initial value of the program counter depends on the specific architecture and design of the computer system. in most cases, the program counter is set to the memory address where the program's execution begins, but there are exceptions, such as interrupt handlers or operating system routines...
Theprogram counter(PC), commonly called theinstruction pointer(IP) inIntelx86andItaniummicroprocessors, and sometimes called theinstruction address register(IAR),[1]theinstruction counter,[2]or just part of the instruction sequencer,[3]is aprocessor registerthat indicates where acomputeris in itsprogr...
SAP computer之program counter Program counter The program is stored in memory with the first instruction at binary address 0000, the second instruction at address 0001, the third at address 0010 and so on. The program counter, which is part of the control unit, counts from 0000 to 1111. Its...
This invention relates to an improved program counter which is capable of both incrementing the program count as well as decrementing the program count. This functionality provides improved implementation of decisions trees in computer logic. The value of a bit is determined and compared to a ...

The address of the current instruction is kept in the 32-bit program counter (PC) register. To execute the code in Figure 6.29, the PC is initialized to address 0x00000830. The processor fetches the instruction at that memory address and executes the instruction, 0x01498933 (add s2, s3, ...
