s55 bus

An in-depth understanding of I2C bus clock synchronization and bus arbitration Each IIC bus device has the same circuit structure of the SDA and SCL pins, and the output drive of the pins is connected with the input buffer. The output is a field effect tube with an open drain path, and the input buffer is a high-input impedance phase generator [1]. This type of c

The AHB is primarily used for connections between high-performance modules such as CPUs, DMA, and DSP, and acts as an on-chip system bus for the SOC, which includes the following features: Single clock edge operation, non-tri-state Implementation mode;Support burst transmission, support segmented transmission, support multiple host controllers, configurable 32-bit ~128-bit bus width, support byte, half-byte

Introduction"Everything is flowing, nothing lasts." Everything melts, nothing is fixed "-Heraclitus (Heracleitus)In about 2003 years, the concept of SOA gradually entered the field of vision, and at one time people happily published their own views of SOA. SOA has become a hot topic for practitioners in the IT industry, especially in the fields of software development and system integration. Many authorities are also predicting the wonderful prospects of SOA, for example, Gartner predicts that b

On-Chip Bus Wishbone Learning (6) bus cycle operation initiation A bus cycle consists of at least one bus operation. The operation is always initiated by the master device. The operation initiated by the master device can be a single read/write, block read/write, or rmw operation. When the master device sets cyc_o to

Now we have many identities on the Internet. For example, I have three or four MSN accounts, QQ, GTalk, and web-based blogs and vblogs, in short, there are many. For small-sized mobile phones and MID-sized handheld devices, we cannot open N clients and N webpages like desktop. In fact, we don't care about the software we are using, we only want to find the contact. D-Bus provides the basis for IPC communication. Many mechanisms are built on D-

Android event bus and android Bus In Android, communication between Activity, Service, and Fragment is troublesome. The main methods are as follows: (1) When broadcast is used, the sender sends a broadcast, and the receiver receives the broadcast for processing; (2) Use Handler and Message. For example, after the download thread completes the download task, it sends a Message to the UI. After the UI receive
