Visualize
Full-page explorers you drive yourself. Change the parameters, step backwards through time, and share the exact state with a link.
Featured · Operating Systems
Type any virtual address and follow it through an AArch64 page table walk. Switch between 3 and 4 levels, map 2 MiB blocks, fill the TLB and trigger translation faults, step by step.
Implements: Virtual Memory & the MMU
Computer Architecture
Tune associativity and block size, replay access patterns, see every hit and miss.
Compilers
Type an expression and watch the tokens, the recursive-descent call stack and the AST.
Databases
Insert and delete keys, watch nodes split and merge, and follow a range scan along the leaves.
Computer Architecture
Flip the bits of an IEEE 754 float and see sign, exponent, fraction and rounding error update.
Computer Architecture
Store an integer and see its bytes land in memory: little- or big-endian, high or low word first.
