registers → 10 × 8 = 80 bytes per register? Too high.

# Understanding Registers, Memory Efficiency, and Am Pogging at 10×8 = 80 Bytes Per Register When working with computer architecture, memory optimization is critical—especially in systems constrained by limited resources. One common question arises around data representation in CPU registers: “Is storing 10 × 8-bit values occupying 80 bytes per register too inefficient?” This article explores register usage, memory allocation, and why the 80-byte figure is often misleading—while actual memory usage per register can be far smaller. ## What Are Registers and Why Do They Matter? Registers are small, high-speed storage locations inside the CPU that hold data temporarily during instruction execution. They enable fast processing by keeping frequently accessed values right next to the execution unit. Common registers include accumulators, program counters, index registers, and status flags.
