From left to right do higher priority (when H/L=1)encoding or from right to left do lower priority (when H/L=0) encoding (i.e. seek the first bit with the value of 1,and the relative bit number of this point will be stored into the low byte (B0~B7) of encoded resultant registerD, and the high byte of D will be filled with 0.(bN L−1) (b H) (b L) (b 0)← Relative bit numberBN S+N L−1BN S↓ B15 ↓ B1 B0← …Direction of extension… 0 0 0 0 0 0 1 0 0 0 1 0 0 0 1 0 0 0 0 0 0 1SHigh Total N L discrete points LowHigh priority search direction Low priority search directionD 00000000 H or L●As shown in the diagram above, for high priority encoding, the bit first to find is b H (with a value of 12), and forlow priority encoding, the bit first to find b L (with a value of 4). Among the N L discrete points there must be atleast one bit with value of 1. If all bits are 0, will not to carry out this instruction, and the all zero flag "D=0" willset to 1.●Because S is a 16-bit register, Ns can be 0~15, and is used to assign a point of B0~B15 within S as theencoding start point (b0). The value of N L can be 2~256, and it is used to identify the encoding end point, i.e. itassigns N L successive single points starting from the start point (b0) towards the left (high position direction)as the encoding zone (i.e. b0~bN L−1). If the value of Ns or NL exceeds the above value, then do not carry outthis instruction, and set the range-error flag "ERR" as 1.7-35
Advanced Function <strong>Instruction</strong>FUN 58 PENCODENCODEFUN 58 PENCOD●If the encoding end point (bN L−1) beyond the B15 of S, then continue extending towards S+1, S+2, but it mustnot exceed the range of specific type of operand. If it goes beyond this, then this instruction can only take thediscrete points between b0 and the highest limit into account for encoding.• The instruction at left is a high priority encode example.X058P.ENCODEN S :Ns :R90H/L NL : 36D : WY 0D=0ERRWhen X0 goes from 0 to 1, will take out toward left 36successive bits starting from B9 (b0) specified by Nswithin S, and perform high priority encoding (becauseH/L = 1). That is, starting from b35 (encoding end point),move right to find the first bit with the value of 1. Theresultant value of this example is b26, so the value of Dis 001AH=26, as shown in the diagram below.SD(b0)B15 B9 B0R0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Y15 Y0X0=R1 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 WY0 0 0 0 0 0 0 0 0 0 0 0 1 1 0 1 0R2 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 0B47 B44↑ B32 High byte always=26(b35)(b26)fill with "0"(encode value)The first bit with the value of 1for high priority encoding7-36
