In this state, the address of the data from external ROM is fetched first for which "ale" is asserted to latch lower order address bus
The two least significant bits of address bus
(LSB) are entries for one block of Cache RAM, this block is called LSB Control, aspect presented in fig.
Using microcontrollers with large address bus
and higher resolution.
Figure 1 shows a program that triggers when the duration between the INTERRUPT line going low and an Address bus
match exceeds a given time, which could be used to determine if interrupt handling latency exceeds a specified time.
Concurrent read and write operation -- Unidirectional read and write interfaces -- Single address bus
-- 18 pin DDR data output path transfers 32 bits + 4 bits of even byte parity per read -- 18 pin DDR data input path transfers 32 bits + 4 bits of even byte parity per write
Defined with minimal overhead, the Atlantic interface utilizes approximately 10 control signals in addition to a variable width data bus, and an optional address bus

MIPS instruction set -- 36-bit address bus
(64-bit virtual address), 64-bit data bus -- 8KB instruction cache, 8KB data cache with 8-bit error detection & correction -- 25MHz pipeline frequency -- 50MHz external clock (a selectable feature for the bus clock rate) -- 64-bit general-purpose registers, integer unit, floating point registers, and floating point unit -- Operating voltage of 3.
6 Gigabyte-per-second address bus
for massive scalability; support for a large 8 Megabyte Error Checking and Correcting (ECC)-protected external cache; and a new error isolation and correction "Uptime Bus" for high-system reliability.
3DSP's new bus controller can support up to 15 simultaneous data transfers with zero overhead arbitration and has a single data bus and an address bus
shared among peripherals.
