Architecture Summary

Processor: $32-$bit RISC, optimized for embedded systems.

Memory: $64$KB RAM, $32$KB ROM, with a configurable cache for mapping algorithm comparison.

Interfaces: UART for keyboard data input; Ethernet and Wi$-$Fi for network storage.

Key Instructions

READ$\_$SENSOR: Inputs data into registers, simulating environmental data collection.

MAX$\_$CALC: Finds the maximum value among data entries for analysis.

Program and Cache Mapping Comparison

Data Collection: Simulate sensor data entry $14$ times into registers R$1-$R$14.$

Data Storage: Store data in one peripheral location and two network storage units.

Maximum Calculation: Use MAX$\_$CALC to determine the highest value, stored in R$15.$

Cache Evaluation: Compare direct$-$mapped, fully associative, and set$-$associative cache mappings by observing performance metrics like cache hit$/$miss rates.

Justification

The $32-$bit RISC processor is chosen for its balance of simplicity and efficiency, crucial for real$-$time processing in embedded systems.
