What is difference between spld cpld?
SPLD - Simple Programmable Logic DeviceAlso known as:PAL (Programmable Array Logic, Vantis)GAL (Generic Array Logic, Lattice)PLA (Programmable Logic Array)PLD (Programmable Logic Device)SPLDs are the smallest and consequently the least-expensive form of programmable logic. An SPLD is typically comprised of four to 22 macrocells and can typically replace a few 7400-series TTL devices. Each of the macrocells is typically fully connected to the others in the device. Most SPLDs use either fuses or non-volatile memory cells such as EPROM, EEPROM, or FLASH to define the functionality.CPLD - Complex Programmable Logic DeviceAlso known as:EPLD (Erasable Programmable Logic Device)PEELEEPLD (Electrically-Erasable Programmable Logic Device)MAX (Multiple Array matriX, Altera)CPLDs are similar to SPLDs except that they are significantly higher capacity. A typical CPLD is the equivalent of two to 64 SPLDs. A CPLD typically contains from tens to a few hundred macrocells. A group of eight to 16 macrocells is typically grouped together into a larger function block. The macrocells within a function block are usually fully connected. If a device contains multiple function blocks, then the function blocks are further interconnected. Not all CPLDs are fully connected between function blocks-this is vendor and family specific. Less that 100% connection between function blocks means that there is a chance that the device will not route or may have problems keeping the same pinout between design revisions.In concept, CPLDs consist of multiple PAL-like logic blocks interconnected together via a programmable switch matrix. Typically, each logic block contains 4 to 16 macrocells, depending on the architecture.

What are the advantage of displacement step diagram of pnumatic control system?
To illustrate the sequence of events in the movement of the actuators. The cylinder movements are classified 1s and 0s (on and off) and the change in state is the difference between the steps. This aids in the programming or wiring of the actuators to perform the required operations.The overall block diagram of a system can be easily drawn by connecting the blocks according to the signal flow. It is also possible to evaluate the contribution of each of the components towards the overall performance of the control system.Block diagram helps in understanding the functional operation of the system more readily than examination of the actual control system physically. It may be noted that a block diagram drawn for a system is not unique, that is, there may be alternative ways of representation of a system in block diagram form.
What is the difference between plc and fpga?
fpga and plc are two completely different things. FPGA( field programmable gate arrays) are building blocks of electronic sysytem where as plc are systems. Comparing these two is like comparing engine with car.
What is fpga?
FPGA - Field Programmable Gate ArrayA field-programmable gate array is a semiconductor device containing programmable logic components called "logic blocks", and programmable interconnects.
What does fpga stand for?
FPGA - Field-programmable gate array is a semiconductor device containing programmable logic components called "logic blocks", and programmable interconnects.

cells is the structural and functional unit of any organism
What is a diagram that shows trophic levels on blocks?

What is the difference between an FPGA and CPLD - they're both programmable logic right?
FPGAs and CPLDs are both programmable logic. However the main difference lies in the architecture of the chips. CPLDs have several programmable PLDs which are interconnected via a programmable connections at the global interconnection matrix. FPGAs on the other hand have individual logic blocks - each block can be programmed to implement a logic function such as AND, OR, NOT etc. These blocks are then connected via programmable switches to implement complete logic functions. Compare the FPGA way of programming individualAND, OR, NOT logic functions and then putting them together to implement a complete logic function, to the CPLD way of programming several complete logic functions at once on inividual PLDs and then bringing these PLDs together via programmable connections. Useful web resources (as visited on 15-09-2008) 1) http://www.xess.com/fpgatut.htm: Good explanation + diagram of chip architectures 2)http://www.edaboard.com/ftopic61996.html: 4th paragraph - good technical explanation of the difference. 2)

What are the capabilities of digital communication systems?
A digital communication system consists of six basic blocks. The functional blocks at the transmitter are responsible for processing the input message, encoding, modulating, and transmitting over the communication channel.
