Memory integer

Because the Multiflow had multiple functional units, it would simultaneously perform both A = B + C and D = E + F storing both results in registers. If the result of the comparison turned out to be false, then it would not store the result D back into memory, and the calculation would be discarded. Because the two operations were done in parallel, this method took no extra time. The integer operation, 7 = 7 -H 1, as well as four other operations, could also be performed simultaneously. [Pg.94]

Instead of reading out two samples from the wavetable memory in the case of linear interpolation, W samples are read out. A Filter Counter is shown which performs this indexing. The base address in the wavetable where the signal vector is read out is provided by the integer part of the phase register, as in the case with linear interpolation. [Pg.180]

Rossum also proposed the use of a cache memory [Rossum, 1994b] as part of the memory lookup path in a sampler interpolator. Since in many cases, the phase increment is less than one, the cache will be hit on the integer part of the table address, consequently, the memory will be free to use for other voices. [Pg.413]

We can look at an equivalent hardware block diagram. Here we have a wavetable being addressed by what is essentially a counter whose rate is changed to vary the pitch. The term drop sample tuning refers to the fact that samples are either dropped (skipped) or repeated to change the frequency of the oscillator. The phase increment is added to the current value of the phase register every sample, and the integer part of the phase is used as an address to lookup a sample in waveform memory to output to aDAC. [Pg.462]

Figure 8.5 Drop Sample Tuning table lookup sampling playback oscillator. The phase Increment Register adds an increment to the current phase, which has a fractional part and an integer part. The integer part is used to address a wavetable memory, and the fractional part is used to maintain tuning accuracy. Figure 8.5 Drop Sample Tuning table lookup sampling playback oscillator.

Numerical tests with different data sets derived from real data collected at the industrial partner in the course of the pilot application reported in Chapter 5 were performed to establish the applicability of the proposed model to problem instances of realistic size. While the numerical performance of mixed-integer programs depends to a large extent on the data set used, some results are provided below. All tests were performed using ILOG OPL 4.2 and CPLEX 10 on a computer with an AMD Athlon XP 2600+ processor and 1 GB memory using a ten-year planning horizon. [Pg.123]

Unless you declare a variable s type, VBA will use the Variant type. You can save memory space if your procedure deals only with integers, for example, by declaring the variable type. [Pg.261]

We ve covered some of the limits which affect memory and the stack. Variables, too, have limits. They can lead to a variety of problems. You can employ three types of variables in a program string, floating-point, and integer. Certain restrictions apply to each of the three. [Pg.37]

Our standard cell benchmarks are from three sources Sun Micro s processor benchmark suite 10, UCLA Dragon benchmark suite 11and MCNC benchmarks 12. These benchmarks have very diverse functionalities and complexities. Sun Micro benchmarks listed in Table 6.1. A are typical CPU circuits such as integer unit, float-point unit, memory management unit, and large register file. They are delivered... [Pg.123]

The small number of coefficients needed can be pre-tabulated and held in memory, and we retain the computational simplicity of the Cartesian formulation along with the vital transformation properties of the spherical Gaus-sians. The coefficients [A, B p, P , i, j,k , i, j, kf ,s,t, ] are simple to construct, and the accumulation of sums like (208) can mostly be done in integer aritb-metic. The extensive cancellation which occurs for higher angular momentum spinors can therefore be done exactly without rounding error. The computational bottlenecks encountered in our preliminary work with the complex recurrence relations for direct constraction of Eg[A,B ,p,P ,n,l,m ,r, 1, m s,t,u] given by [107] are completely eliminated. The calculation of these coefficients and the spinor coefficients of the next section now constitutes a trivial part of the computational load. [Pg.174]

They used a neural network running on IBM s latest soda-can-sized supercomputer that learned to recognize the different brain patterns that occurred prior to each of Herman s memories. Thus they could predict, most of the time, whether a memory would be happy or sad before Herman actually had the recollection They were now able to localize events in time with greater precision using their joint discovery of fractal Fibonacci numbers, which allowed them to probe between the integers. [Pg.54]

Simple sequential assignment of memory can implement list structures. Three elementary data structures are illustrated as follows by list examples. A pile of papers on a desk is a stack. A group of cars in a one-lane traffic bottleneck is a queue. A collection of candies can be a bag. Actually, in computer terms the data objects (papers, cars, and candies) are stored in the named data structure, and all three are generally called linear lists. The data type (e.g., real, integer, complex) is another attribute that must be noted in planning the data structure. It can change the space needed by each node (complex values require more bits). [Pg.99]

Here is a distinct approach, promising some practical improvement. Suppose that we seek the product Ab of a 1000 X lOOOmatrix A by a vector b, both filled with zeros and ones and use a computer with 100 bit precision. Each entry of Ab is at most 1000 and occupies almost 10 bits, so that 10 entries of Ab can be easily computed and stored by using one arithmetic operation and a single word of memory, thus almost by 10 times improving the classical approach. The algorithm can be extended to matrices and vectors whose entries are bounded by integers [see Pan (1984) Bini and Pan (1994)]. [Pg.191]

Commercial workloads have been shown to have dramatically different behavior compared to scientific and engineering workloads (Barroso et al., 1998 Keeton et al., 1998). Due to the fraction of time spent in the memory system and lack of instruction-level paraUehsm, there is a relatively small gain from improving integer processor performance (also, there is no floating-point computation). Commercial applications also make frequent use of operating system services and I/O, making the performance of system software more important. [Pg.15]

Fractional derivatives provide an excellent instrument for the description of memory and hereditary properties of various materials and processes [37-50]. This is the main advantage of fractional derivatives when compared with the classical integer-order models, in which such effects are in fact neglected. The mathematical modeling and simulation of systems and processes, based on the description of their properties in terms of fractional derivatives, naturally leads to differential equations of fractional order and to the necessity for solving such equations. [Pg.383]
