Syntax:

• MTQ Len C5

Description:

The MTQ (memory to queue) instruction performs data transfer from a specified memory location into a specified queue. The destination queue can be a local or a remote one. The burst length, memory address, and remote communication offsets are decoded from the last value stored by the LAL instruction. The inputs following the MTQ instruction are as follows:

• Len: The length is a temporization directive for the shaker. Since the MTQ is a delayable memory instruction, i.e., it does not cause a stretch to the micro-code, a burst length of 1 can be used for the different bursts.
• C5: When C5 = 1, exceptions are conditioned by the top of the stack (see below for the exceptions that are conditioned by C5).

Microcode Pattern:

Takes 1 cycles to execute.
    Example: MASM code see below.

Example :

AGU_D ZERO 0x0001000000000bb8 !! AGU output, with the encoding: 
                              !! burst=1, memory address=0xbb8, 
                              !! local communication
							  
LAL 0                         !! Loads the output of the AGU

MTQ 1 0                       !! Copies the data of memory address 
                              !! 0xbb8 to the local queue
