56 Ver Function Description Port Control GPIO Ports 는 GPxODIR 레지스터를통해각 Port 별로 Output mode 로설정되고또한 GPxIDIR 레지스터에의해각 Port 별로 Input mode 로설정된다. 각 Port 의설정상태는 GPxDIR 레지스터를통해확인할수있다. GPxODIR 레지스터와 GPxIDIR 레지스터설정시 1 인비트만해당동작으로설정되고, 인비트는어떠한영향을미치지못한다. GPIO Ports 의출력레벨은 Output mode 로설정된상태에서 GPxOHIGH 레지스터를통해 High Level 로설정되고, GPxOLOW 레지스터를통해 Low Level 로설정된다. Output level 의설정상태는 GPxOLEV 레지스터를통해확인할수있다. GPIO Ports 의입력레벨은 GPxILEV 레지스터를통해확인할수있다. 각 Port 에연결된 Pull-up 저항은외부입력이존재하거나출력인경우에는 Pull-up 을제거하면, 신호레벨이 Low 일때누설전류를줄일수있다.

80 Ver Function Description DMA Operation - Transfer Hierarchy DMA 전송은그림 2 와같은 3 단계의계층구조를갖는다. 최상위단계의전송을 DMA Transfer 라정의한다. DMA Transfer 전송은 DMA 가전송하는전체데이터의양을의미하며 Control 레지스터에있는 Transfer Size 로전송량을결정하게된다. 차상위단계전송을 Burst Transaction 으로정의한다. Burst Transaction 에서전송하는데이터의양은 Control 레지스터에있는 Burst Size 로설정하게되며보통 Peripheral 들의 FIFO 크기에맞추어설정한다. 일반적인 Peripheral 들은메모리처럼필요한모든데이터를한번에전송하지못하므로 Peripheral 내부의 FIFO 단위로쪼개서전송하게된다. 한가지주의할사항은여기서설정하는 Burst size 가 AMBA Burst transfer 의 burst size 가아니라는점이다. 최하위단계전송은 AMBA Burst Transfer 이다. Burst Transaction 은 AMBA Burst Transfer 단위로나뉘어진다. 이단계의전송에서사용자가설정하는부분은없으며하드웨어적으로관리된다. 사용자는 Burst Size 보다적은 Transfer Size 값을설정하는것이가능하다. 이러한경우 Burst Transaction 은설정된 Transfer size 양만전송되며 DMA 전송이종료된다. Transfer Size 로전송량조정 DMA Transfer Burst Size 로전송량조정 Burst Transaction Burst Transaction Burst Transaction Single Transaction AMBA Burst Transfer AMBA Burst Transfer AMBA Burst Transfer AMBA Single Transfer Figure 9-2 DMA Transfer hierarchy - Transfer type 사용자는 DMA 설정에서데이터전송의종류 (Transfer type) 를지정해야한다. Transfer Type 은아래의 4 가지중에하나가된다. 1. Memory to Memory 2. Memory to Peripheral 3. Peripheral to Memory 4. Source Peripheral to Destination Peripheral 8 CONFIDENTIAL Advanced Digital Chips, Inc

81 Ver Memory to Memory 의의미는 Source Address 가 Memory 이고 Destination Address 도 Memory 로지정한경우를말한다. Memory to Peripheral 의의미는 Source Address 는 Memory 이고 Destination Address 는 Peripheral 로지정한경우이다. 즉메모리에있는데이터를 Peripheral 의버퍼등으로옮기는것을뜻한다. 이렇게사용자가 Transfer Type 을지정하는이유는 handshake 과정이필요한지아닌지를 DMA 에게알려주기위함이다. DMA 는메모리가아닌 Peripheral 과의데이터전송을수행할때에는 Handshake 방식으로진행한다. 메모리가아닌 Peripheral 들은데이터전송을위한준비과정과시간이필요하며데이터전송량도한정되어있다. Handshake 방식은 Peripheral 이데이터가준비되었을때만 DMAC 가데이터를전송하도록유도하므로필요한방식이다. 하지만 Peripheral 이메모리인경우는언제든 Access 가가능하므로이러한 handshake 과정은필요하지않다. 따라서사용자는 Transfer type 을지정하여 Peripheral 과의데이터전송에서 handshake 방식이필요한지아닌지를알려주어야한다. - Flow Controller Flow controller 란 DMA 전송량을결정하는모듈을말한다. Flow Controller 는 DMAC 또는 Peripheral 중에하나로정해진다. 만약 DMAC 가 Flow controller 가되면 DMA 전송량은 Transfer Size 에설정된값으로결정된다. 또한 Peripheral 이 Flow Controller 역할을할수있다. 이러한경우 DMAC 는 Peripheral 의 Request 신호에맞추어데이터를전송하게하게되며 Transfer size 에설정된값들은무시된다. DMA 전송을종료하기위해서는마지막데이터를요구할때 Last Request 신호를보내면된다. DMAC 가 Last Request 신호를받게되면마지막요청에대한데이터전송을수행한후에 DMA 전송이종료된다 Linked List Operation - LLI LLI(Linked List Item) 는 DMA 전송을위해필요한기본적인정보들을담고있는배열이다. LLI 가담고있는내용은 Source Address, Destination Address, Next LLI Address, Control 정보이렇게 4 가지이다. Linked List Operation 은 DMAC 가첫번째 LLI 를읽어서내부레지스터들을갱신한후 DMA 전송을수행하고종료되면 Next LLI 주소를통해다음번 LLI 를읽어들이는방식으로동작한다. 아래의그림은 LLI 의구조를설명하는그림이다. Advanced Digital Chips, Inc. CONFIDENTIAL 81

DMAC 는 Next LLI Address 가 x 임을확인하면현재읽은 LLI 가마지막임을알게된다. 그러므로 LLI 가실제주소 x 에놓이면수행되지않으므로주의해야한다. - Multi Block Transfer LLI 로기술되어있는데이터를전송하는경우를 Multi Block Transfer 라고부르기도한다. 즉하나의 LLI 가전송하는데이터를 Block 이라고정의하며 LLI 의개수는 Block 의개수가된다. 또한 Block 사이즈는각각의 LLI 에포함된 Control 레지스터의 Transfer Size 로정의된다. 아래의그림은 Multi Block Transfer 에대한계층구조를보여주고있다.

84 Ver Auto Reload Operation Auto Reload Operation 의기본동작은 DMA 전송이완료되었을때 Control 레지스터를다시 Reload 하여 DMA 전송을반복하는것이다. 반복회수는 Auto Reload count 레지스터값으로정하게된다. Auto Reload 가 1 회발생할때 Auto Reload Count 값이 1 씩감소하며 이되면 Auto Reload 는발생하지않는다. Auto Reload Operation 은별도의모드설정이없으며 DMA 전송이완료되었을때 Auto Reload Count 레지스터가 이아니면 Auto Reload 를수행하는방식이다. - Transfer Hierarchy Auto Reload Operation 은 Linked List Operation 처럼 Multi Block Transfer 로분류된다.

148 Ver Address Generation Address Generation 블록은 Screen Refresh 를위한 Memory Read Request Address 를생성한다. User 에의해셋팅된 LCD Base Address 에내부적으로해당모드에따른 offset address 가더해져서생성된다. - FIFO / Request Control FIFO Control 블록은내부 FIFO 의 Read Request 및 Write, Read Pointer 를제어한다. Read Request 및 Write, Read Pointer 는 Horizontal Active 구간의끝나는시점에서 Reset 된다. FIFO Control 블록은두개의 Clock Domain 을갖는다. 프레임메모리로부터읽어온데이터를 FIFO 에 Write 하는 System Clock Domain 과 FIFO Data 를읽어 Screen 에디스플레이하기위한 Video(Dot) Clock Domain 으로되어있다. FIFO 의 Write/Read Data Bus 는 32 Bit 이며, Control 레지스터 [16] Bit 에의해 <16 or 24> Bit per Pixel(RGB) Color 모드를선택할수있으며, 초기값은 RGB 16 Bit(5:6:5 Format) Color 모드로되어있다. 만약 RGB 16 Bit(5:6:5 Format) Color 모드를선택한다면, 한번의 FIFO Write/Read 동작에 2 Pixel 을처리하게되며, 32 Bit 중하위 [15:] 16 Bit, 상위 [31:16] 16 Bit 순으로디스플레이된다. 1 Pixel 은 16 Bit 이며 R 값이 [15:11], G 값이 [1:5], B 값이 [4:] 순으로되어있다. Control 레지스터 [16] Bit 에 1 을셋팅하여 RGB 24 Bit(8:8:8 Format) Color 모드를선택한다면, 한번의 FIFO Write/Read 동작에 1 Pixel 을처리하게되며, 32 Bit 은 { Dummy 8 Bit[31:24], R[23:16], G[15:8], B[7:] } 로구성된다. LCD Control 레지스터 [18:17] Bit 에따라, 매라인 Horizontal Active 구간에서 FIFO 의 Read Pointer 를체크하여프레임메모리비디오데이터 Read 에대한 Request 신호가발생한다. 이 Bit 이, 11 일때는 FIFO 가절반비었을때, 1 일때는 4 분의 1 이비었을때, 1 일때는 8 분의 1 이비었을때 Request 신호가발생한다. 그리고, 매라인 Horizontal HSYNC 구간에서 FIFO 는, LCD Control Register [18:17] Bit 에따라,, 11 일때는 Full, 1 일때는절반, 1 일때는 4 분의 1 이채워진다. 내부 FIFO 는 256 x 32 로되어있다.
