Abstract(in English) | We have previously proposed Linear Array Pipeline Processor (LAPP) which can map an inner loop of conventional VLIW codes onto Function Unit (FU) array and use minimum required FUs to exploit performance per watt. However, by this structure, LAPP has a constraint that the maximum codes to be mapped define the number of FUs. Though a large number of FUs can be predetermined, it will consequently prevent the power, area and performance balance. To solve this problem, we propose a fine-grained time sharing mechanism to extend the FU array of LAPP, to remove from the physical constraint due to the limited size of FU array. We evaluate the perfor-mance, power consumption and area of the extended LAPP. The results indicate that the extended LAPP executes about 6-fold faster than the baseline LAPP. The performance per area is increased by 16 % and the performance per watt is reduced by 20 % accordingly. |
