Status bits in computer organization
http://www.ee.nmt.edu/~rison/ee308_spr02/supp/020123.pdf WebWe can determine the number of bits of offset as the problem states that: - Data is word addressable and words are 8 bits long - Each block holds 16 bytes As there are 8 bits / byte, each block holds 16 words, thus 4 bits of offset are needed. This means that there are 5 bits left for the index. Thus, there are 25 or 32 blocks in the cache.

http://www.ee.nmt.edu/~rison/ee308_spr02/supp/020123.pdf WebThe detection is done by the Arithmetic and Logic Unit (ALU) of the CPU. Upon detection corresponding flag is set to ON status. These flags have bit positions allotted in the …
Web• If the status bit is one of eight status bits, it is indicated by a 3-bit select number. • If the select status bit is 1, the output is 0; else it is 0. • A 1 generates the control signal for the branch; a 0 generates the signal to increment the CAR. • Unconditional branching occurs by fixing the status bit as always being 1. The status register is a hardware registerthat contains information about the state of the processor. Individual bits are implicitly or explicitly read and/or written by the machine codeinstructions executing on the processor. The status register lets an instruction take action contingent on the outcome of a previous … See more 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) … See more Status flags enable an instruction to act based on the result of a previous instruction.
