Visualize the contents of main memory.

memories

memories is a program to visualize the contents of main memory. Memory addresses are rendered as cubes in an isometric projection, with the color and opacity of a cube determined by the value storied at its corresponding virtual memory address.

Compiling and Running

memories relies on architecture-dependent functionality and expects an x86-like GNU/Linux environment.

$ make

Controls

• q: Quit.

• j/k: Scroll viewport by one cube in the z-direction.

• b/f: Scroll viewport by one chunk in the z-direction.

• +/-: Increase/decrease chunk side length by one cube in all dimensions.

• 0-9: Toggle visibility of z-planes (only supports indices 0 through 9).

• h/l: Zoom in/out.

• t: Move viewport to text segment.

• d: Move viewport to data segment.

• e: Move viewport to end segment.

• a: Move to base address of data array.

• s: Save a snapshot of the viewport as ./memories_<TIME>_<ADDR>.png.

Examples

1. Random values: Iterate over data, assigning random values to each element every second.

2. Neural network: Perform a stochastic gradient descent with a two-input, two-hidden-node, one-output neural network, training once every second.
