Processor Local Bus Functional Model Toolkit User's Manual

6.3.11 Compare () Command
The compare command enables the user to compare two values and store the results in the condition
register. Each compare instruction executes in one PLB clock cycle.
• SRC (two are required)
This parameter specifies the internal register value to be used as a source of the compare
instruction. Each compare instruction requires two SRC parameters. Valid values are SR,R0-31.
• DST
This parameter specifies the condition register destination of the compare instruction. Valid values
are CR0-7.
Example: compare(R0,R1,CR1)
6.3.12 Add () Command
The add command updates an internal master register with the result of an addition between an
internal register and an immediate value. Each add command executes in one PLB clock cycle.
• DST, [hex value up to 4 bytes]
These two parameters specify the 32-bit internal destination register to be updated and the
immediate hexadecimal value to be added to the destination register. The DST must be R0-31, SR,
or CR.
Example: add(R0,01)
6.3.13 Sub () Command
The sub command updates an internal master register with the result of a subtraction between an
internal register and an immediate value. Each sub command executes in one PLB clock cycle.
• DST, [hex value up to 4 bytes]
These two parameters specify the 32-bit internal destination register to be updated and the
immediate hexadecimal value to be subtracted from the destination register. The DST must be R0-
31, SR, or CR.
Example: sub(R0,01)
6.3.14 AND () Command
The AND command updates an internal master register with the result of a bit-wise AND operation
between an internal register and an immediate value. Each AND command executes in one PLB
clock cycle.
• DST, [hex value up to 4 bytes]
These two parameters specify the 32-bit internal destination register to be updated and the
immediate hexadecimal value to be AND'd with the destination register. The DST must be R0- 31,
SR, or CR.
Example: and(R0,FFFFFFF0)
