srec_fastload - LSI Logic Fast Load file format
The FastLoad Format uses a compressed ASCII format that permits files
to be downloaded in less than half the time taken for Motorola
The base‐64 encoding used is "A‐Za‐z0−9,.". The data is encoded in
groups of 4 characters (3 bytes, 24 bits).
The character ’/’ is used to introduce a special function. Special
Annnnnn Defines an address.
Bnn Define a single byte.
Cnnnn Compare the checksums. The checksum is a simple positive
16‐bit sum, of the data bytes only.
EAA Define the program’s entry point. The address will be the
current address as defined by the A command. (The AA number in
this command is ignored.) This must be the last entry in the
KAA Clear the checksum. (The AA number in this command is
Sname,X Define a symbol. The address of the symbol will be the current
address as defined by the A command.
Znn Clear a number of bytes.
In general, binary data will expand in sized by approximately 1.4 times
when represented with this format.
Here is an example LSI Logic Fast Load format file. It contains the
data “Hello, World[rq] to be loaded at address 0.
