GPU(Graphic Processing Unix)
->AI Deep Learning에 사용 -> 많은 연산
Accelerator : 특정기능을 빠르게 하는 초고속 Processing 회로.
-많은 연산에 특화된 전용 System.
-FPGA : 새로운 기능을 Update가 가능하며, Programming이 가능한 Digital Chip. Accelerator 전용 Chip
-ASIC : Accelerator 전용 칩.
Analog Signal(continuous)

Digital Signal(Discontinuous)

Digital Discipline:
-두가지 이산값만 취급.
-“0” or “1”, “TRUE” or “FALSE”
-Bit(Binary digit)
Number System:
-Decimal numbers(10) : 5374_10=5*10^3+3*10^2+7*10^1+4*10^0
-Binary numbers(2) : 1101_2=1*2^3+1*2^2+0*2^1+1*2^0=1310
Hexadecimal Numbers(16): 4AF_16=4*16^2+A(10)*16^1+F(15)&16^0=010010101111_2=1199_10
Binary values and Range:
-Decimal numbers: N-digit, 10N개, Range=>[0,10^(N-1)]
-Binary numbers: N-bit, 2N개, Range=>[0,2^(N-1)]
