Swanium::Core::MemoryBus

Inherits Reference < Object

Platform-neutral, 20-bit V30 memory interface. The hardware map will replace FlatMemory without changing CPU code.

Instance methods

consume_wait_cycles

Some hardware I/O operations synchronously stall the V30. A bus accumulates those costs while handling an instruction, and the CPU consumes them before reporting that instruction's total cycle count.

Source

read_io(port : UInt8) : UInt8

Default open-bus I/O behavior keeps FlatMemory suitable for CPU specs.
