Types ¶
type Mapper ¶
type Mapper struct {
// Zero value for unmapped areas.
Zero uint8
// contains filtered or unexported fields
}
Mapper for bank switched memory access.
func NewMapper ¶
func NewMapper() *Mapper
NewMapper creates a new mapper with 0xff as the zero value.
type Masked ¶
type Masked struct {
Memory
// Mask is the memory mask. To limit memory access to 1k for example, use
// a mask of 2^10-1 (0x3ff).
Mask uint16
}
Masked memory access allows one to restrict and/or translate 16-bit memory to a smaller range.
type Memory ¶
type Memory interface {
// Fetch a byte
Fetch(addr uint16) (value uint8)
// Store a byte
Store(addr uint16, value uint8)
}
Memory implements a 16-bit address bus.
type RAM ¶
type RAM []uint8
RAM is Rendom Access Memory.
