Allocate()

static void * SRL::VDP2::VRAM::Allocate ( uint32_t size, uint32_t boundary, VDP2::VramBank bank, uint8_t cycles = 0 )

inlinestatic

Linearly Allocates Vram in a bank and returns address to start of allocation. Allocation fails if there is not enough free space in the bank or if access requires too many cycles.

Parameters

size	Number of bytes to allocate
boundary	Byte Boundary that the allocation should be aligned to (must be multiple of 32 for all VDP2 Data types)
bank	The VRAM bank to allocate in
cycles	(Optional) Number of Bank Cycles this data will require to access during frame(0-8).

Returns

void* start of the Allocated region in VRAM (nullptr if allocation failed)

Note

Any VRAM padded to maintain alignment to a requested boundary is rendered inaccessible to further allocations until VRAM is cleared and reset.
