How the 128k memory can segment into blocks with 16bit address lines?

A 128 KB memory can be segmented into blocks using 16-bit address lines by leveraging the addressable memory space defined by those lines. With 16 bits, you can address up to 2^16 (or 65,536) unique addresses, which corresponds to 64 KB of memory. To accommodate the full 128 KB, the memory can be divided into two segments of 64 KB each, allowing the system to reference the blocks efficiently. Thus, the memory can be organized into blocks, with each block containing 64 KB and addressed via the 16-bit lines, typically using techniques like paging or segmentation for management.

What is instruction pointer?

The instruction pointer (IP), also known as the program counter (PC) in some architectures, is a special register in a computer's CPU that tracks the address of the next instruction to be executed in a program. As the CPU processes instructions sequentially, the instruction pointer is updated to point to the subsequent instruction, allowing for the orderly execution of code. In the case of control flow changes, such as jumps or function calls, the instruction pointer can be modified to point to a different location in memory. This mechanism is essential for the sequential flow of program execution.

What is a property of an Address Bus?

An address bus is a vital component in a computer's architecture that carries addresses from the CPU to other components, such as memory and input/output devices. Its width, measured in bits, determines the maximum addressable memory capacity; for instance, a 32-bit address bus can address up to 4 GB of RAM. Additionally, the address bus is unidirectional, meaning it only transmits data from the CPU to other devices, not the other way around.

Why are there 12 bits for the memory address?

Having 12 bits for a memory address allows for addressing 2^12, or 4,096 unique memory locations. This is commonly sufficient for smaller systems, as it provides a total addressable memory space of 4 kilobytes (KB). The choice of 12 bits balances the need for a compact addressing scheme while still accommodating reasonable amounts of RAM for various applications. In larger systems, more bits may be used to increase the addressable memory capacity.

Where does the address operand of the instruction copied?

The address operand of an instruction is typically copied into the instruction register (IR) during the instruction fetch phase of the instruction cycle. From the IR, the operand can be accessed by the control unit or the arithmetic logic unit (ALU) for execution. In some architectures, the address operand may also be stored in specific registers, depending on the instruction type and the addressing mode used.

What is instruction format of cmp?

The instruction format of the CMP (compare) instruction varies by architecture, but generally, it follows a similar structure across different assembly languages. Typically, it includes an opcode followed by two operands, which can be registers, immediate values, or memory locations. The CMP instruction compares the values of the operands and sets the processor flags (such as Zero Flag, Sign Flag, and Carry Flag) based on the result, without modifying the actual values. This allows subsequent conditional instructions to determine the flow of control based on the comparison.

What are incrementer and decrementer latch in 8085?

In the 8085 microprocessor, incrementer and decrementer latches are used to manipulate the address bus. The incrementer latch increases the address in the program counter (PC) by one, allowing the CPU to fetch the next instruction. Conversely, the decrementer latch decreases the address, which can be useful for looping or managing stack operations. These latches facilitate efficient control over program execution flow during instruction fetching.
