Core Logic for Pentium /M1/M2/K5/K6 based Business and Multimedia PCs

ALADDiN 5 is the fifth generation 586 chipset from AcerLabs. It maintains the best system architecture (2-chip solution) to achieve the best system performance with the lowest system cost (TTL-free). ALADDiN 5 consists of two BGA chips to give the 586-class system a complete solution with most up-to-date features and architecture for the most engaging multimedia/ multithreading OS and software applications. It utilizes the modern BGA package to improve the AC characterization, resolves system bottleneck and makes the system manufacturing easier.

M1541 includes the higher CPU bus frequency (up to 100 MHz) interface for all Socket-7 compatible processors, PBSRAM and Memory Cache L2 controller to reduce cost and enhance performance, high performance FPM/EDO/SDRAM DRAM controller, PCI 2.1 compliant bus interface, smart deep buffer design for CPU-to-DRAM, CPU-to-PCI, and PCI-to-DRAM to achieve the best system performance. It also has the highly efficient PCI fair arbiter. M1541 also provides the most flexible 64-bit memory bus interface for the best DRAM upgrade-ability and ECC/Parity design to enhance the system reliability.

With the AGP interface design, the dedicated PCI_66 AGP interface can be concurrent with CPU and PCI interface. The deep buffer of the read and write buffer design makes the utilization of memory bandwidth more efficient. The interface supports AGP specification V1.0. The M1541 supports up to 128 entries table look aside buffer for Graphic Address Remapping Table (GART). The interface not only supports the AGP 66MHz PCI protocol, but also the AGP 1X and 2X sideband address function.

With the concurrent bus design, PCI-to-PCI access can run concurrently with CPU-to-L2 and CPU-to-DRAM access, PCI-to- DRAM access can run concurrently with CPU-to-L2 access. M1541 also supports the snoop ahead feature to achieve the PCI master full bandwidth access (133Mbytes). M1541 also provides the enhanced power management features including ACPI support, suspend DRAM refresh, and internal chip power control to support Microsoft's On Now technology OS.

ALADDiN 5 is designed to meet the requirements of all Socket 7 processors including business, multimedia Notebook PCs.
