6 srec_fastload - LSI Logic Fast Load file format
7
9 The FastLoad Format uses a compressed ASCII format that permits files
10 to be downloaded in less than half the time taken for Motorola S‐
11 records.
12
13 The base‐64 encoding used is "A‐Za‐z0−9,.". The data is encoded in
14 groups of 4 characters (3 bytes, 24 bits).
15
16 The character '/' is used to introduce a special function. Special
17 functions are:
18
19 Annnnnn Defines an address.
20
21 Bnn Define a single byte.
22
23 Cnnnn Compare the checksums. The checksum is a simple positive
24 16‐bit sum, of the data bytes only.
25
26 EAA Define the program's entry point. The address will be the cur‐
27 rent address as defined by the A command. (The AA number in
28 this command is ignored.) This must be the last entry in the
29 file.
30
31 KAA Clear the checksum. (The AA number in this command is
32 ignored.)
33
34 Sname,X Define a symbol. The address of the symbol will be the current
35 address as defined by the A command.
36
37 Znn Clear a number of bytes.
38
39 Size Multiplier
40 In general, binary data will expand in sized by approximately 1.4 times
41 when represented with this format.
42
44 Here is an example LSI Logic Fast Load format file. It contains the
45 data “Hello, World[rq] to be loaded at address 0.
