Built-in 8085 Intelligence

Accelerate your microprocessors coursework with opcode synthesis, cycle-by-cycle register explanations, and instant loop detection.

Natural Language Assembly Generator

Type desired logic in English (e.g. "Add contents of HL to BC and store at 2000H") to generate clean 8085 assembly instructions.

// Prompt: "BCD Addition of two numbers"
MVI A, 45H
ADI 38H
DAA

Real-time Cycle & Flag Explainer

Step through assembly code with live explanations of T-states, bus signals, and flag bit mutations (S, Z, AC, P, CY).

// Flag Insight:
Carry [CY] set due to 8-bit overflow (0xFF + 0x01). Accumulator resets to 0x00.

Smart Bug & Loop Fixer

Detects missing `RET` statements, uninitialized stack pointers, and infinite `JMP` recursion before execution stalls.

// AI Warning [Line 14]:
Notice: JNZ LOOP creates infinite recursion because D register is never decremented (`DCR D` missing).

Opcode T-State Optimizer

Optimizes machine cycles by recommending faster opcodes (e.g. replacing `MVI A, 00H` (7 T-states) with `XRA A` (4 T-states)).

// Optimization Tip:
Replaced MVI A, 00H (7 T) with XRA A (4 T). Saves 42% execution cycles!

8085

Zero-lag WebAssembly architecture emulation tailored for microprocessors instruction understanding.

Inspect register pairs (BC, DE, HL), track stack pointer pushes/pops, and test I/O devices with microsecond timing fidelity.
