mem_read()

uint8_t mem_read	(	v_memory *	mem,
		uint16_t	offset
	)

Lowest level memory read access abstraction. Typecasts the offset to void* + base to get the actual pointer. Return the value.

Parameters

offset	from the base ptr in bytes
mem	cpu's memeory context under exec

Returns

uint8_t, byte read from the memory

mem_ref()

void* mem_ref	(	v_memory *	mem,
		uint16_t	offset
	)

plain reference to the memory location

Parameters

offset	from the base ptr in bytes
mem	cpu's memeory context under exec

Returns

void*, memory reference to the target location

mem_write()

void mem_write	(	v_memory *	mem,
		uint16_t	offset,
		uint8_t	val
	)

Lowest level memory write access abstraction. Typecasts the offset to void* + base to get the actual pointer. Populates from val into the memory.

Parameters

offset	from the base ptr in bytes
val	to write onto memory
mem	cpu's memeory context under exec

short_mem_read()

uint16_t short_mem_read	(	v_memory *	mem,
		uint16_t	offset
	)

Wrapper over memory access primitives to read a byte off the base offset void* + base. Returns the value.

Parameters

offset	from the base ptr in bytes
mem	cpu's memeory context under exec

Returns

uint16_t, short read from the memory

short_mem_write()

void short_mem_write	(	v_memory *	mem,
		uint16_t	offset,
		uint16_t	val
	)

Wrapper over memory access primitives to read a byte off the base offset void* + base. Populates from val into the memory.

Parameters

offset	from the base ptr in bytes
val	to write onto memory
mem	cpu's memeory context under exec
