(5) Coding Data Format
The Stripe Data Entity (SDE) (= Stripe coded data with byte stuffing (PSCD) + end marker (SDNORM /
SDRST)) Coding/decoding of one stripe portion as performed. In case of the multi-striped (construct the
multi stripes) stripes are activated one at a time.
(6) Marker Code
The SDE end marker is supported. (SDNORM = 02h, SDRST = 03h, ABORT = 04h)
(During coding the marker code previously set in the register is outputted. During decoding, the marker code
detected by requesting an interrupt to MPU when the marker is detected is read out of register.)
(7) Rough Estimate of Coding and Decoding Time
(T1: M65761FP as a Whole, T2: Processing Time of the Arithmetic Coding Section Alone)
The total number of clocks needed for coding and decoding 1 page (stripe) is calculates roughly using the
following equations.
T1
≈ (p Lp) + (9/8 C) + ( Lp)
p:
Number of pixels/line
: about 0.3
–S ((1 – ) p Ltp – Lp) [clock]
Lp:
Number of lines/page
T2
≈ (p Lp) + (9/8 C)
Ltp:
Number of TP line/page
–S ((p Ltp) – Lp)) [clock]
C:
Number of coded data bits/page
S = 1: TP exists
0: No TP
: about 10
