For 1 Bpp and [FX] < 8:
f
where
A = [TC/R] - [C/R]
B = RNDDN([C/R] x [FX] ÷ 4)
C = 16 x RNDUP(B ÷ 16)
D = C - B
E = (B x 8 ÷ [FX] + D) ÷ 2
F = A + E
For 2 Bpp:
f
where
A = [TC/R] - [C/R] + 1
B = RNDDN([C/R] x [FX] ÷ 8)
C = 16 x RNDUP(B ÷ 16)
For 4 Bpp:
f
where
A = [TC/R] - [C/R] + 2
B = RNDDN([C/R] x [FX] ÷ 16)
C = 16 x RNDUP(B ÷ 16)
For all cases above where:
