Accumulator (A): An 8-bit register that is part of every ALU operation.
is widely considered the gold standard for introductory material on 8-bit architecture, mirroring the comprehensive depth of his classic textbook, microprocessor 8085 ppt by gaonkar
The microprocessor 8085 is an 8-bit processor developed by Intel Corporation in 1977. It is one of the most popular microprocessors of its time and is still widely used in many embedded systems. The 8085 microprocessor is a part of the 8080 family of processors and is known for its simplicity, ease of use, and low cost.
From the Intel 4004 to the 8085. This section sets the context, contrasting the microprocessor with a microcontroller and establishing why the 8-bit 8085 was a watershed moment in the late 1970s. Gaonkar’s emphasis on the "three-bus architecture" (Address, Data, Control) is visually reinforced here. The 8085 microprocessor is a part of the
The ALU performs all numerical and logical operations. These include addition, subtraction, AND, OR, and XOR. It uses data from the Accumulator and temporary registers to generate results.
Addressing modes define how the microprocessor accesses the operand data. Vectored: 0024H) │ RST 7.5 (Maskable
[Highest Priority] TRAP (Non-Maskable, Vectored: 0024H) │ RST 7.5 (Maskable, Vectored: 003CH, Edge-Triggered) │ RST 6.5 (Maskable, Vectored: 0034H, Level-Triggered) │ RST 5.5 (Maskable, Vectored: 002CH, Level-Triggered) │ [Lowest Priority] INTR (Maskable, Non-Vectored)
The time needed to complete one basic access operation with memory or an I/O device (e.g., Opcode Fetch, Memory Read, Memory Write). An instruction cycle consists of 1 to 5 machine cycles.
