Details
OverviewThe MPC106 provides an integrated high-bandwidth, high-performance, TTL-compatible interface between a 60x processor, a secondary (L2) cache or additional (up to four total) 60x processors, the PCI bus, and main memory. This section provides a block diagram showing the major functional units of the 106 and describes briefly how those units interact.Figure 1 shows the major functional units within the 106. Note that this is a conceptual block diagram intended to show the basic features rather than how these features are physically implemented on the device.FeaturesThis section summarizes the major features of the 106, as follows:• 60x processor interface — Supports up to four 60x processors — Supports various operating frequencies and bus divider ratios — 32-bit address bus, 64-bit data bus — Supports full memory coherency — Supports optional 60x local bus slave — Decoupled address and data buses for pipelining of 60x accesses — Store gathering on 60x-to-PCI writes• Secondary (L2) cache control — Configurable for write-through or write-back operation — Supports cache sizes of 256 Kbytes, 512 Kbytes, and 1 Mbyte — Up to 4 Gbytes of cacheable space — Direct-mapped — Supports byte parity — Supports partial update with external byte decode for write enables — Programmable interface timing — Supports pipelined burst, synchronous burst, or asynchronous SRAMs — Alternately supports an external L2 cache controller or integrated L2 cache module• Memory interface — 1 Gbyte of RAM space, 16 Mbytes of ROM space — Supports parity or error checking and correction (ECC) — High-bandwidth, 64-bit data bus (72 bits including parity or ECC) — Supports fast page mode DRAMs, extended data out (EDO) DRAMs, and synchronous DRAMs (SDRAMs) — Supports 1 to 8 banks of DRAM/EDO/SDRAM with sizes ranging from 2 Mbyte to 128 Mbytes per bank — ROM space may be split between the PCI bus and the 60x/memory bus (8 Mbytes each) — Supports 8-bit asynchronous ROM or 64-bit burst-mode ROM — Supports writing to Flash ROM — Configurable external buffer control logic — Programmable interface timing• PCI interface — Compliant with PCI Local Bus Specification, Revision 2.1 — Supports PCI interlocked accesses to memory using LOCK signal and protocol — Supports accesses to all PCI address spaces — Selectable big- or little-endian operation — Store gathering on PCI writes to memory — Selectable memory prefetching of PCI read accesses — Only one external load presented by the MPC106 to the PCI bus — Interface operates at 20–33 MHz — Word parity supported — 3.3 V/5.0 V-compatible• Support for concurrent transactions on 60x and PCI buses• Power management — Fully-static 3.3-V CMOS design — Supports 60x nap, doze, and sleep power management modes and suspend mode• IEEE 1149.1-compliant, JTAG boundary-scan interface• 304-pin ceramic ball grid array (CBGA) package
