Host Computer: An array processor may be attached to a host computer by the control unit. The reason of the host computer is to broadcast a sequence of vector instructions by CU to the PEs. Therefore, the host computer is a general-purpose machine that acts as a manager of the full system.
Array processors are special purpose computers which have been adopted for the following:
SIMD array processor on the big scale has been developed by NASA for earth resources satellite image processing. This computer has been named extremely parallel processor (MPP) because it haves 16,384 processors that do work in parallel. MPP gives real- time time varying scene analysis.
Though, array processors are not commercially popular and are not usually used. The reasons are that array processors are complex to program compared to pipelining and there is difficulty in vectorization.
The demand placed on a system is explained by a lognormally distributed random variable with mean 50 and standard deviation of 10. The capacity of the system is modeled by a Weibul
Network Properties There are many properties are associated with interconnection networks:- 1) Topology: It signify how the nodes a network are organised. A variety of top
Propositional model: Hence a propositional model was simply an assignments of truth values to propositions. In distinguish, a first-order model is a pair (Δ, Θ) where
Q. Sequential Execution of Instructions in RISC? Let's describe pipelining in RISC with an illustration program execution sample. Take the given program (R denotes register).
What is meant by opening a data file A data file is a file that can be read from or written to. Data files are particularly useful when large amounts of data are involved. Each
What is the necessity of an interface? Any device that has to be linked to a CPU requires an interface. This takes care of the mismatch in speed, data and electrical character
Signalling transfer point (STP) exist in (A) Strowger exchange (B) SS7 (C) Local area network (D) PABX Ans: STP that is stand f
What is virtual memory? Virtual memory is a method used in some large computer systems that allow the user to construct program as by a large memory space were available, equal
What is importance of RAS and CAS in SDRAM? SDRAM acquires its address command into two address words. This uses a multiplex scheme to save input pins. The initial address word
Q.What is Canonical and Standard Forms? An algebraic expression can express in two forms: i) Sum of Products (SOP) for example (A . B¯) + (A¯ . B¯) ii) Produ
