c# - How can I access a Dictionary through a key hashcode? -

i have dictionary that: dictionary<mycompositekey, int> clearly mycompositekey class designed implements iequalitycomparer , has gethashcode method. as far know, dictionary uses key's hash access value, here's question: while can access value via dict.trygetvalue(new mycompositekey(params)) , wanted rid off new overhead on each access. for reason wondering if there's way access value directly key's hash (which can compute lower overhead). there no way that. note hash collisions may occur, there many keys in dictionary<,> matching given hash. need equals find out (if any) correct. you talk new overhead. sure significant in case? if is, consider making mycompositekey immutable struct instead of class . might faster in cases, eliminating need garbage collector remove "loose" keys memory. if mycompositekey struct , expression new mycompositekey(params) loads params onto call stack (or cpu registers or whatev...

signal processing - DFT phase and amplitude by using vhdl core in FPGA -

how find out phase , amplitude of analogue waveform ? receiving 1 analogue signal 1 sensor, using analogue waveform want find out dft (phase, amplitude) fundamental frequency , second harmonic. converted analogue signal through adc applied fpga. in fpga want use ip dft 4.0 core, dft core output imaginary , real values. using how can determine phase , amplitude of fundamental , harmonics? for each complex (re, im) output can calculate magnitude , phase this: magnitude = sqrt(re*re + im*im); phase = atan2(im, re); if know frequency of fundamental (and harmonics) can calculate appropriate fft output bin index using formula: i = n * f / fs where n fft size, f frequency of interest , fs sample rate.

Why are mutable values allowed in Python Enums? -

this of follow on why mutable values in python enums same object? . if values of enum mutable (e.g. list s, etc.), values can changed @ time. think poses of issue if enum members retrieved value, if inadvertently changes value of enum looks up: >>> enum import enum >>> class color(enum): black = [1,2] blue = [1,2,3] >>> val_1 = [1,2] >>> val_2 = [1,2,3] >>> color(val_1) <color.black: [1, 2]> >>> color(val_2) <color.blue: [1, 2, 3]> >>> my_color = color(val_1) >>> my_color.value.append(3) >>> color(val_2) <color.black: [1, 2, 3]> >>> color(val_1) traceback (most recent call last): ... valueerror: [1, 2] not valid color i think given normal python idioms okay , implication being users can use mutables enum values, understand can of worms might opening. however brings second issue - since can enum memeber value, , value can mutable, must doing lo...

c++ - One definition rule warning -

i have been bitten nasty "one definition rule" violation. afraid of having lots of subtle bugs in projects. for example, following program result in null pointer dereference visual studio 2015: source1.cpp: ---------- struct s { double d = 0; }; void foo() { s s; } source2.cpp: ----------- struct s { int = 0; }; int main() { int value = 5; int& valueref = value; s s; // valueref erased due s::d initialization source1.cpp valueref++; // crash } this compiles no warnings. it's nasty because source2.cpp doesn't use source1.cpp . if remove source1.cpp project, still compiles, , there no problem anymore. in large projects, seems hard ensure no cpp file "locally" define struct or class defined name. i have classes such point , serie , state , item , ... though ok in small cpp files, realize it's not safe. is there compiler warning catch such bugs ? if not, best practices avoid odr violation...

caching - Solving for hit ratio in Effective Access Time given cache access -

i given following question: consider memory system cache access time of 10 nano sec (nsec) , memory access time of 200 nano sec (nsec). if effective access time 10% more cache access time, hit ratio? my intuition tells me set using eat equation know: [h(memory access + tlb access) + (1-h)(2*memory access + tlb access)] , solve there. however, solution sets 1.1*10 = 10*h + (1-h)(210) solving there ratio 189/190. where equation use come from? have been taught 1 gave means solve problems hit ratios , access times.
