Title: Memory management unit for digital signal processor
IPC: G06F9/34
Filed: 1987-03-02
Abstract: A memory management unit suitable fo use in a digital signal processor having internal and eternal memories is described. The unit is especially designed to facilitate numeric algorithms such as fast fourier transforms, auto-correlation and digital filtering by relieving the programmer from the need to monitor memory accesses. Automatic post-updating of memory addresses is provided after indirect memory references. Also, memory boundary-checking is performed according to a user-specified modulus value, and a memory reference is automatically adjusted to fall within the user-specified address range. A dual-access register file stores initial memory addresses and their associated modulus values and in a dual-bus embodiment a pair of address generation units provides post-updates of the addresses stored in the register files. Direct addressing of memory is also supported by the memory management unit and a page register internal to the unit allows the user to specify memory page information during a direct address operation.. A modulo-adjust portion of the address generation unit implements any user-specified modulii in the range 0 to 64, as well as modulii of 128, 256 and 512. A method of operating a memory management unit to provide the features obtained by the instant invention is also described.

Patent EP-0388843-A3 (EP)
IPC: G07B17/00
Filed: 1990-03-19
Abstract: A technique for reconfiguring in the field 
external devices in communication with postage meters, 
the external devices having an external device feature 
set that may be selectively enabled or disabled by 
software. The technique provides security so that any 
changes to the feature set is authorized. The meter (10) is 
capable of being put into an I/O configuration mode by 
suitable entries from the keyboard (14), in which mode it is 
inhibited from printing postage. The meter (10) has a 
storage register (26) for a current or old I/O configuration 
number (IOCN), and can receive a desired new IOCN via 
keyboard (14) entry. The meter (10) calculates an encrypted I/O 
configuration request code that depends on the new 
IOCN. The I/O configuration request code, when 
communicated to a data center computer (25) along with other 
validating identification information, is checked by 
the data center computer (25) which computes the I/O 
configuration request code using the same algorithm.  
If the two values agree, the data center ccmputer (25) 
calculates an encrypted I/O configuration enable code 
that depends on the meter serial number. This is 
communicated to the meter (10), which receives the I/O 
configuration enable code and also calculates a I/O 
configuration enable code using the same algorithm as 
the data center computer (25). If the I/O configuration 
enable codes agree, the meter (10) overwrites the old IOCN 
with the new IOCN, thereby reconfiguring the meter (10) and 
the external devices.
