Reprogram the hardware to perform the required activity in the idle slot (task marked si on the diagram). This could either be a neighbor cell power measurement, which requires a 160 bit receive, a neighbor cell FCCH burst search, which requires a 1408-bit receive, or a neighbor cell SCH burst receive, which a requires a 176-bit receive starting at an arbitrary offset within a frame. This task is triggered either by the frame interrupt for the frame before the idle slot or by an extra interrupt at timer wraparound if the idle slot activity commences more than two timeslots into the idle frame Reprogram the hardware for normal TCH activity following the idle slot (task marked ei on the diagram). Triggered either by the start of an idle slot power measurement or SCH receive, or by the frame interrupt during an idle slot FCCH receive Process the samples received during the idle slot. This consists of either a simple power measurement, a frequency burst search or an SCH equalization and channel decode. This task is triggered by the end of the idle slot activity

As ever the deadline for task (i) is 59 s, and this task runs directly in the ISR. Task (ii) should complete before the next burst receive, so the deadline is seven timeslots, or 3.9 ms. Tasks (v), (vi) and the rst (vii) of each four form a group and their deadline is nine timeslots (5.1 ms) since the transmitted data must be available before the next transmit slot. Tasks (iii) and (iv) form a pair and their deadline is governed by the maximum allowed round trip delay time for GSM of 100 ms. After taking account of the fact that it takes eight frames to receive a speech block and eight frames to transmit one, we nd that a deadline of four frame periods (18 ms) is permissible for tasks (iii) and (iv). Tasks (viii) and (ix) only occur once every 104 frames. Their deadlines, in combination with the layer 2 and layer 3 processing of SACCH messages, are determined by the fact that a received SACCH message should have been processed in time for the next idle slot, and that an SACCH message for transmission must be assembled in the time between the previous idle slot and the rst SACCH transmit frame. Thus a deadline of 12 frames (55 ms) is acceptable for each direction of SACCH processing. The worst case for task (x) is an SCH receive starting immediately after the TX burst nishes (RX starts timeslot 5), which is two timeslots after the frame interrupt. Thus the deadline for task (x) is 1.1 ms. The worst case for task (xi) is an SCH receive starting just before timeslot 5 in the idle slot. The task must have completed by the start of timeslot 7 to set up for the next normal receive. Hence again the deadline is two timeslots, or 1.1 ms.

The result of task (xii) will not be needed before the next SACCH transmission, so this shares the deadline of 55 ms with other SACCH processing.

From my earlier discussion, you can see that the real time deadlines involved in GSM layer 1 fall into ve clusters. I list these in the following table: Deadline 59 s 1 ms Context FIQ L1 Thread Tasks Reading 16 sample pairs from baseband receive ADC into main memory. Main layer 1 state machine, idle slot setup and teardown during traf c mode, control channel encode. Receive equalization, control channel decode, traf c channel encode, speech encode. Speech decode, traf c channel decode. Idle slot data processing, SACCH channel encode and decode.
