Jumps with Relative Addresses

Name:

Specification:

@ ← RA with
RA ← @+4*XYZ for a jump forward,
RA ← @+4*(XYZ-2²⁴) for a jump backward.

Timing:

1υ

Description:

Executes an unconditional jump. Usually, a label is used to specify the jump target. The assembler will automatically determine whether it is a jump forward or backward and selects the appropriate instruction.

JMP: A JMP command treats bytes X, Y, and Z as an unsigned 24-bit integer XYZ. It allows a program to transfer control from location λ to any location between λ - 67,108,864 and λ + 67,108,860 inclusive, using relative addressing as in the B and PB commands.
