  • Computer Bus Characteristics
    Upendra Sharma (upsharma.in) Computer Bus A bus, in computing, is a set of physical connections (cables, printed circuits, etc.) which can be shared by multiple hardware components in order to communicate with one another. The purpose of buses is to reduce the number of "pathways" needed for communication between the components, by carrying out all communications over a single data channel. This is why the metaphor of a "data highway" is sometimes used. If only two hardware components communicate over the line, it is called a hardware port (such as a serial port or parallel port). Characteristics A bus is characterised by the amount of information that can be transmitted at once. This amount, expressed in bits, corresponds to the number of physical lines over which data is sent simultaneously. A 32-wire ribbon cable can transmit 32 bits in parallel. The term "width" is used to refer to the number of bits that a bus can transmit at once. Additionally, the bus speed is also defined by its frequency (expressed in Hertz), the number of data packets sent or received per second. Each time that data is sent or received is called a cycle. This way, it is possible to find the maximum transfer speed of the bus, the amount of data which it can transport per unit of time, by multiplying its width by its frequency. A bus with a width of 16 bits and a frequency of 133 MHz, therefore, has a transfer speed equal to: Upendra Sharma (upsharma.in) Types of Buses In reality, each bus is generally constituted of 50 to 100 distinct physical lines, divided into three subassemblies: The address bus (sometimes called the memory bus) transports memory addresses which the processor wants to access in order to read or write data.

  • Model 225E MIDI Decoder / Preset Manager the 225E MIDI Decoder Translates Incoming MIDI Messages Into Analog Voltages and Pulses
    Description - model 225e MIDI Decoder / Preset Manager The 225e MIDI decoder translates incoming MIDI messages into analog voltages and pulses. These control signals appear on three kinds of "busses" for subsequent distribution to 200e series modules. Four busses are routed internally to 200e series modules that respond directly to MIDI messages. Four more handle only note messages, decoding them into front panel voltages that represent pitches, velocities and pulses with sustain information. An additional six busses handle controller and clock messages (two controllers each), which are translated into standard 0-10 volt control voltages. Busses: Note and Controller message assigments to Pulses and CVs. Note messages are applied to busses A,B,C,D,E,F,G, and H; Continuous Controller and Clock messages are handled by busses J, K, L, M, N, and P. Each bus responds to one selected MIDI channel. But more than one bus may be assigned to the same channel, allowing multiple controllers CVs and note messages to be derived from a single MIDI channel. First select a bus for assignment use "bus select" to illuminate the LED next to the desired bus. MIDI NoteOn and pitch translation: Busses A-H There are two sets of Note messages busses: A-D and E-H. Internal busses will be explained in more detail later. For these busses the following display will appear: Bus:A Ch:15 Poly Tr:24 Ft:75 Vl:/ With the cursor buttons, select a data type. Use the knob to the right of the cursor buttons to enter data for the following fields: Ch: MIDI Channel.

  • What Is a DMA Controller?
    Direct Memory Access (DMA) For the execution of a computer program, it requires the synchronous working of more than one component of a computer. For example, Processors – providing necessary control information, address etc. buses – to transfer information and data to and from memory to I/O device etc. The interesting factor of the system would be the way it handles the transfer of information among processor, memory and I/O devices. Usually, processors control all the process of transferring data, right from initiating the transfer to the storage of data at the destination. This adds load on the processor and most of the time it stays in the ideal state, thus decreasing the efficiency of the system. To speed up the transfer of data between I/O devices and memory, DMA controller acts as station master. DMA controller transfers data with minimal intervention of the processor. What is a DMA Controller? The term DMA stands for direct memory access. The hardware device used for direct memory access is called the DMA controller. DMA controller is a control unit, part of I/O device’s interface circuit, which can transfer blocks of data between I/O devices and main memory with minimal intervention from the processor. The DMA transfers the data in three modes which include the following. a) Burst Mode: In this mode DMA handover the buses to CPU only after completion of whole data transfer. Meanwhile, if the CPU requires the bus it has to stay ideal and wait for data transfer. b) Cycle Stealing Mode: In this mode, DMA gives control of buses to CPU after transfer of every byte.
